Coming in both flexible and rigid designs, different PVC fittings can be used for various home needs, making it a staple in any redesign. But why should you use it in your next project?

To help you better understand the PVC advantages, we are sharing all the perks of plumber PVC fitting, explaining just what is PVC pipe and what are fittings, and how you can use them in your next project. Let's dive right in!

1. PVC Is Energy Efficient

One of the top advantages of PVC pipes is that they are super energy efficient. The creation and formation of PVC pipes use less energy to manufacture than other pipe alternatives, like iron and concrete. Additionally, PVC pipes are lighter than other pipe options, further saving energy in the transportation process.

2. Better Water Quality

When opting for PVC fittings, you will also improve your water quality. How does this work exactly? Well, since PVC pipes are so smooth, it is more challenging for sediment to accumulate, ensuring the pipes remain smooth and strong. With this, contaminants won’t be able to bind to the walls of the pipes, creating better quality water while improving the sewage pipe networks. This is one of the primary advantages of polyvinyl chloride pipes that you can’t get from other materials.

3. PVC Provides Water Conservation

Water conservation is an important environmental topic, and something PVC pipes work to address. If you’re wondering “what is PVC pipe used for?”, conserving water is at the top of the list. This is because PVC pipes preserve and control water resources, which prevents pollution. Due to their smooth design, pump costs are lower and there are fewer leaks, avoiding any unnecessary water loss.

4. Low Costs

Another of the PVC advantages is that it helps reduce costs. With PVC pipes, you are not only able to get lower installation rates, but lower breakage rates, life cycle costs, and other expenses related to the installation of PVC pipes. Since these pipes are so durable, they cost less in the long run, requiring less maintenance for a more budget-friendly option.

5. Longevity

If you’re looking for a long-term solution, PVC pipes are the way to go. This material has a life expectancy of over 100 years. Yes, really! With that in mind, these pipes can last in your home through your entire lifespan, and then some. And coming at a lower cost, this is a wonderful lifetime investment.

6. PVC Is Chemical Resistant

There’s a reason there are so many uses of PVC pipe fittings in homes and other locations. Since PVC pipes are resistant to many chemical reagents, as well as disinfectant chemicals, they are great to use in infrastructure projects where chemicals are abundant. With PVC pipes, you will have a system that’s built to withstand strong acids, fluorides, brine, mineral oils, and more.

7. Corrosion Resistance

PVC safety is top-notch, especially in terms of its resistance to corrosion. As other pipes made from various different materials will deal with corrosion, PVC pipes are less susceptible to this effect. In fact, corrosion can even lead to bursting water mains, which can cause major damage, but PVC will be able to withstand this for more secure pipes. This is important as corrosion can have a big impact on the safety of your drinking water. And with PVC pipes having one of the lowest pipe break rates, there's a reason it’s a top choice over cast iron, concrete, and steel alternatives.

8. Less Blockage

Another perk of opting for plumber PVC fitting choices is that, due to their smooth design, there’s much less water flow resistance, helping to further prevent potential blockages and failures from occurring. With the use of PVC pipe fittings, water will flow seamlessly at maximum pressure, avoiding both blockages in the pipes, as well as buildup in sewage. It’s all part of their long-term performance promise.

9. PVC Is Easy to Install

On top of all the other perks, PVC pipes are one of the easiest to install. Actually, these pipes are said to be 30% faster to install than other options. This is wonderful for quickly getting a new set of pipes up and running with ease, all while ensuring long-term durability that’s fit to last through the years in your home.

10. PVC Is Lightweight

As Blackhawk Supply mentioned when it comes to energy-efficient PVC advantages, PVC pipes are much lighter than their counterparts. For this reason, they are easy to carry and even easier to install without lifting too heavy and cumbersome pipes. Additionally, their lighter weight helps ensure they won’t cause injury when installing, requiring less manpower to install.

11. Safety

We all want to ensure a safe and comfortable environment, so PVC safety is especially important. Thankfully, this non-toxic material is safe for some reasons. PVC pipes are flame-resistant and won’t react to chemicals. For this reason, plumber PVC fitting solutions are used across industries as a safe, sustainable choice.

Conclusion

When redoing a space, choosing a solution that is functional, cost-effective, and built to last is a must, and PVC pipes check everything on that list.

An HVAC unit stands for heating, ventilation, and air conditioning systems. These appliances allow you to warm or cool your homes and include components like furnaces, air conditioners, heat pumps, ductwork, evaporator coil, actuators, thermostats, and other comfort controls.

The Blackhawk Supply team is sure that an HVAC unit is crucial to ensuring that our homes are cooled and heated and that we enjoy good air quality. An HVAC unit will either move air inwards or outwards depending on whether it is heating or cooling the house. The heat pump and the furnace are responsible for either trapping the heat or releasing it using the blower and ductwork.

How HVAC Systems Work

HVAC systems, generally speaking, are made up of four major elements: your heating element, your cooling element, your ventilation element, and your controller element. Contained within each element are various components that help each element perform its role.

The furnace and the heat exchanger are both parts of the heating element; they are responsible for heating cold air in order to supply high temperatures. The evaporator coil, condensing unit, and refrigerant lines comprise the cooling element, which is responsible for supplying cold air.

Both the hot and cold air is supplied through various air vents and ductwork that are part of your ventilation system. However, the air that passes through the HVAC's ventilation system needs to be regulated. This is where actuators and dampers come in.

What Is an HVAC Damper?

A damper, also known as a zone damper, is a mechanical component of your HVAC system that is responsible for the regulation of airflow. More specifically, it is a valve or a movable plate that regulates central airflow as well as redirects the flow to various spaces within the home. This is an essential HVAC component that gives the system its ability for room temperature and climate control.

There are two types of dampers, which are categorized by type of control. Manually-controlled dampers are manual dampers that can be operated using a handle outside the duct. On the other hand, automatically-controlled dampers, also known as automated zone dampers, are those that are operated using electric or pneumatic motors, which are then controlled automatically using the thermostat.

Electrical automated zone dampers have two principal designs:

• The first design uses a small shaded-pole synchronous motor with a rotary switch to disconnect the motor when the damper opens and when the damper closes. When power is applied to the “open damper” terminal, the motor runs until the damper is open. In the same way, when power is applied to the “close damper” terminal, the motor runs until the damper is closed. This design doesn't close the damper fully, however, as simultaneous closure of all the dampers in your HVAC system might damage the furnace or your air handler. That is why this damper design only obstructs a portion of the air duct.

• The second electrically-powered damper design makes use of a spring-return mechanism and a shaded-pole synchronous motor instead of a rotary switch. This way, the damper is opened using the force of the spring while it is closed using the force exerted by the motor. In cases where electrical power is removed either through power failure or forceful removal, the damper opens to allow air to flow.

In both designs, damper actuators are used for automatic regulation of the amount of air that is produced by the HVAC systems.

What Is an HVAC Damper Actuator and How Does It Work?

By definition, an actuator is a device component that is capable of, or rather responsible for, moving and controlling certain components of a mechanism or system. This is done by sending a control signal to the actuator, which is then converted into mechanical motion, often a rotational movement, and acts upon its environment. This control system can range from relatively simple such as manual input or a fixed-mechanical input to relatively complex and very high precision, such as a piece of software.

An HVAC actuator, more specifically, is responsible for controlling the damper. These are powered devices that are used to adjust the flow of fresh air and smoke within an HVAC system. HVAC dampers are controlled by these devices using a low-voltage signal.

Though there are other actuator types, like hydraulic actuators, manual actuators, and valve actuators, there are two basic types of actuator dampers: electric actuators and pneumatic actuators. 

4 Main Types of Actuators

There are four common types of actuators that we will elaborate on such as:

• Spring Return On/Off
• Air Volume Modulating
• Chilled Water On/Off
• PIBCV Modulating

Spring Return On/Off Smoke Dampers

Spring return on/off actuators is used in HVAC units for activating the fire and smoke damper in the system. Motorized fire and smoke dampers have the capability of blocking fire and smoke from passing through the ductwork in an HVAC system. They must be fast-acting and fire-resistant, and they can be the on/off or modulating type.

They must also have a failsafe in case of an emergency. These fire and smoke damper actuators shouldn't be confused with a fire damper, which only blocks the flow of fire but does not block smoke moving through the ducts. These types of actuators will usually be found in pressurized air systems.

Variable Air Volume Modulating

An Air Volume Modulating actuator is a part of the VAV (variable air volume) box of an HVAC unit. The VAV box consists of a few parts, such as the Air Volume Modulating actuator, the damper, and a coil that can be used for heating or cooling by either using electric energy or a water pump.

The actuator's role is to modulate the damper to regulate airflow and air pressure in the HVAC system according to the different zones. VAV boxes are responsible for the air supply and air control of the HVAC units.

Chilled Water On/Off

Chilled Water On/Off actuators controls the flow of chilled water that is moved throughout the system by evaporator coils. The valves will then be activated depending on the supply of air or the temperature that the air-conditioned space requires.

The chilled water that is going through the evaporator coils is solely controlled by the desired temperature of a thermostat. These types of actuators are not as common today, they are basic and are mostly found in older HVAC units.

PIBCV Modulating

PIBCV (Pressure Independent Balancing and Control Valve) Modulating are pressure-independent, modernized alternatives to the traditional chilled water on/off actuators used in chilled water A/C units.

They are highly accurate and water-resistant, modulating with on/off options and low energy consumption while not being noisy. These PIBCV actuators also tend to be very small components. These actuators are not in contact with actual chilled water; rather, the coldness is transferred from the valve to the actuator.

The Importance of HVAC Dampers and Damper Actuators

Dampers are the final control element for regulating almost all airflow in HVAC systems. Actuator applications are numerous, as they serve as an interface between the mechanical system and the control system, which is paramount for accurate control. But providing the ability to control the HVAC dampers are the actuators.

Typically, about 80% of the digital signals transported to HVAC systems are received by the actuator. They are perhaps the most critical component of the entire system since all other portions of the air system suffer when they are positioned inaccurately. More often than not, the accuracy of the damper and damper actuator is not an important selection criterion. However, the controller will not be able to compensate for this inaccuracy. That is why it is important to select the correct type when selecting one for your HVAC system.

A current transformer, or CT, is a metering system that primarily functions to convert one current that is carried by a CT meter socket into a secondary current that is usually of smaller value, though it can be larger as well. This function exists for a few purposes, including protection and measurement.

CT cabinets, or current transformer cabinets, are basically enclosures, and their primary role is to protect operators from potential electric shocks. They are used in both indoor and outdoor applications, as well as for both residential and commercial applications. Basically, CT cabinets and sockets are crucial components of any and all electrical metering systems.

What Are the Main Parts of the Electrical CT Enclosure Box?

The main parts of the electrical CT enclosure box are the cover, metal box, and screws. The cover is the top piece that opens and screws onto the metal box. The metal box is the main part of the enclosure and contains the CTs. The screws hold the cover and the metal box together. Depending on the application, some CT cabinet models can also include a hinged door, mounting holes, factory-installed wiring buss, and look-through glass.

CT Cabinets ClassificationS by National Electrical Manufacturers Association (NEMA)

All CT cabinets must meet the standards of the National Electrical Manufacturers Association (NEMA) and/or the Underwriters Laboratories (UL). NEMA and UL classify the varying types of cabinets available.

NEMA ratings are used to specify where and in what types of environments electrical enclosures can be used. For example, they might be classified according to their ability to withstand rain, snow, sleet, and even windblown dust. Among the most popular types of current transformer cabinets are a UL Type 1 and a NEMA 3 enclosure. Below we've listed some of the other types of CT cabinets rated by NEMA.

• NEMA Type 1

• NEMA Type 2

• NEMA Type 3

• NEMA Type 3R

• NEMA Type 4

• NEMA Type 4x

Current Transformer Cabinets can be also classified based on their structural design and functional features:

• Bar-type CT Style Cabinets. These cabinets are designed to house bar-type current transformers which are primarily used for large current applications. They are robust and typically used in industrial settings where high current levels are involved. The cabinets help in protecting the CTs from external elements and ensure safety.

• Window-type CT Style with Bus Included. This type of cabinet contains window-type current transformers, which have an opening through which a primary conductor (bus) passes. The bus is included in the cabinet, making it a complete package for easy installation. They are suitable for applications where space is a constraint as they combine two components into one.

• CT Cabinet with PT (Potential Transformer) Cab. In this arrangement, the CT cabinet also includes a section for housing a potential transformer (PT). This is convenient for measuring both current and voltage levels in an electrical system. It’s widely used in utility and substation applications where both current and voltage monitoring are critical.

• Transocket CT Cabinet with CT Rated Socket Installed. This cabinet type combines a current transformer with a specially rated meter socket. It's designed to facilitate the connection of metering equipment directly to the current transformer. This is often used in commercial settings where metering accuracy and ease of installation are crucial.

• CT Cabinet with PT Rack Options. Similar to the CT cabinet with PT cab, this type also accommodates potential transformers but with more customizable rack options. The racks can be adjusted or customized according to the requirements, allowing for more flexibility in installation. It’s ideal for applications where customization and adaptation to various configurations are necessary.

Additionally, CT cabinets are not just classified by the environment they can be used in but also by their design. A few common ones are:

• Freestanding/Pedestal Mount CT cabinets.

• Pad-mounted CT cabinets.

• Wall-mounted CT cabinets.

• Double-door model CT cabinets.

When Would a Current Transformers Metering Socket be Needed?

Knowing when a current transformer metering socket is needed will help ensure worker safety and regulatory compliance.

A CT metering socket usually becomes necessary when a certain amperage or voltage is reached. According to the EUSERC (Electric Utility Service Equipment Requirements Committee), on the west coast, if an application is above 200 amps, then a CT will be required. In other places, the application needs to be greater than 400 amps to require a CT. For either, the voltage is at 480.

The primary reason for this requirement is safety. Any worker or operator who is responsible for servicing and replacing meters is at risk of serious injury. Also, it's important to note that the primary applications for an electric meter socket are commercial and industrial rather than residential, and requirements should be checked before installation. These requirements include the correct meter socket, internal wiring configurations, colors, meter form, etc.

As you know, a CT meter cabinet is usually used with a CT meter socket. Though usually mounted separately, in some instances, the socket is mounted directly on the CT cabinet itself. In some cases, and in certain areas like the Southwest, a transocket, which houses both the meter socket and CT, is sometimes used.

What Is the Main Difference Between CT and PT Electrical Metering?

The main difference between CT and PT Electrical Metering is that, while a CT meter measures the current through the load, a PT meter measures the potential difference (voltage) across the load. This is because a current transformer (CT) uses a magnetic field to create a current in its secondary winding proportional to the primary current, while a potential transformer (PT) uses a voltage to create a current in its secondary winding proportional to the primary voltage. In shorter terms, CT meters are used to measure current, while PT meters are used to measure voltage.

Additional Features of CT Metering Sockets

CT metering sockets can come with an array of added features that serve their own purposes. For example, one of the most popular electric meter socket types is a meter socket with a disconnect. This disconnect is a switch that can isolate all of the wirings in a commercial property or residence from the power source (commonly, this source is the utility power source).

In general, bypass options are varied; there's auto or plunger bypass, which allows the CT to be automatically shunted when the meter is pulled out of the socket.

A few other features can include a provision for a VT, voltage transformer, pack or PTs, and potential transformers. Potential and voltage transformers serve to decrease the voltage that runs through a meter socket to ensure safety for operators.

Another example is a Square D meter socket, which comes with a variety of helpful features, including the option of being ringless.

Blackhawk Supply CT Cabinet Selection

In summation, every piece of equipment that makes up an electric metering system is essential to ensure it runs smoothly and, more importantly, safely. Current transformers, CT cabinets, and CT metering sockets go hand in hand in providing a safe working environment for operators and workers.

RTU, which stands for rooftop unit, is a crucial piece of equipment that ensures that we have comfortable lives. The regular maintenance of this unit is important for many reasons. Annual RTU maintenance can save you costs in the long run; having an RTU unit that works efficiently and discovering issues before they become severe problems can maintain your unit's longevity.

It is highly recommended that at the very least, once a year, a technician comes to inspect your RTU unit. Failure to do so can lead to expensive repair costs and discomfort in the event of a breakdown of the unit.

In addition, having a well-maintained HVAC unit can also save you on heating and cooling bills. Technicians will help you diagnose issues with your RTU unit ahead of time and will help you address those issues before they become serious matters.

What Are The Most Common Rooftop HVAC Unit Problems?

Rooftop AC units can experience an array of issues, all of which should be addressed as soon as possible.

Here are the most common RTU unit problems:

• Problems with air balance and airflow problems, such as issues relating to the ductwork.

• Dirty equipment, as this can obstruct airflow. Dirty coils or dirty pilots are especially common issues.

• Leaking refrigeration equipment.

• Thermostat problems.

• Tripped or burnt fuses can over time cause severe damage to an RTU unit.

• Strange noises can be an indicator of an equipment malfunction.

• Mechanical wear and tear over time which is common in all household equipment and regular maintenance can remedy this situation.

Rooftop HVAC Maintenance Checklist

It is highly recommended that the seasonal maintenance of a rooftop unit be performed by a trained technician. If, however, you have experience in handling rooftop HVAC units then you can get your supplies for HVAC dampers and roll up your sleeves and begin.

It is important that all steps on this checklist are followed by either you or, more preferably, a professional HVAC technician:

• Turn off the power: All power must be turned off prior to performing maintenance on rooftop HVAC units.

• Clean and replace every air filter: Air filters must be routinely replaced but at a minimum, you must clean the screen of an air filter once a year.

• Inspect fans: Make sure that all fans are clean and functioning properly.

• Inspect belts: They are a common culprit for wear and tear in an RTU unit.

• Check gas pressure and test for leaks: Leaky refrigerants can cause your rooftop HVAC units to malfunction over time.

• Inspect the refrigerant charge: Make sure that there is enough airflow coming through the coils and ensure that there are no leaks.

• Check the heat exchangers: Carefully inspect every heat exchanger to make sure that there is no rust build-up.

• Check coils: If you encounter any dirty coils, it is crucial to clean them to ensure your unit will function properly.

• Check economizer: Make sure that dampers, actuators, and temperature sensors are still functioning correctly.

• Check drainage: Clogged drain pipes can cause damage by not allowing water and other liquids to properly escape the RTU unit.

• Perform an amperage test: This will highlight any refrigeration problem that may be caused by wear and tear. If the unit needs to use more power, it is a sign that something needs to be replaced. Worn bearings or worn rods can cause a mechanical failure of the RTU.

When performing the final HVAC unit inspection to ensure that everything works well, it is important to check for voltage imbalances which can also indicate a malfunction down the line. If there is a voltage imbalance it can cause motor failure by overheating the equipment.

Once all the cleaning and inspection have been completed, it is crucial to fasten every screw firmly into place.

Tips for HVAC Heating Season

It is recommended to perform annual preventive maintenance of your rooftop unit HVAC system, and it is even better to perform this maintenance before the arrival of the winter months to ensure that during the cold days your HVAC system will deliver a smooth operation, even at extreme operating temperatures.

There are additional key components to check when preparing your RTU for the heating season such as:

• Inspect all components of your HVAC unit: make sure that heat exchangers, main burners, coils, and vents are fully functioning.

• Clean all components: Before the heating season, it is crucial to ensure that all vents, especially exterior parts, are regularly cleaned to ensure that nothing will pollute or obstruct airflow into your home in the winter months.

• Perform tests: It is important to ensure that all components function properly, especially testing the temperature limit switch is a key component for the heating season.

RTU Maintenance During The Cooling Season

Before the cooling season, it is important to ensure that all refrigeration equipment with the HVAC system, such as pipework and ducts, are unobstructed and clean. It is important to pay extra attention to the condensation drain, which may get clogged with regular wear and tear and debris which could damage your RTU over time.

Conclusion

Annual maintenance is key to the longevity of your rooftop unit. It is best practice to invite a technician to perform the maintenance and make sure your HVAC unit performs well throughout the year.

In addition, it is also recommended to inspect, clean, and get acquainted with your RTU before the heating and cooling months to ensure that nothing will affect your HVAC unit's performance.

If possible and the weather allows for it, it is highly recommended to clean your RTU HVAC unit (especially its air filters) once a month for the best result. During the winter months, this may not always be a possibility. However, it can be performed during the transition months and can help you maintain the integrity of your rooftop AC unit.

For HVAC supplies and replacement parts, make sure you choose a trusted supplier who can aid you in getting the right tools.
