Some homeowners might not be aware, but it’s important that they give thoughtful consideration to how water valves are installed in their home plumbing. These play a vital role in regulating water flow, so it’s essential that you’re well-informed about the available options, particularly the specific applications that are most suitable for your plumbing system.

The majority of valves used in residential plumbing are designed to be integrated into the water supply system. The primary function of these valves is to either regulate, stop, or change the flow of water, whether it originates from a private well or a public water utility line.

When selecting valves for your plumbing system, it’s best to settle for those manufactured from such materials as brass, bronze, plastic, and PVC. These are the common materials used when designing a typical plumber valve.

Types of Water Valves

Different valves are utilized when it comes to installing your bathtub, showers, water heater, sinks, and outdoor faucets. In a typical home plumbing system, the following valves are commonly used:

1. Ball Valve

Ball valves are frequently employed in main water line installations and feature a ball with a hole in the middle that is connected to the handles. They also have a lever handle that can be positioned to allow full water flow or completely shut it off.

To determine if a ball valve is open or closed, simply observe its handle. If it’s parallel to the water pipes, the valve is open. Conversely, if the handle is perpendicular to the pipe, the valve is closed. In this case, the flow of water to your home is effectively cut off.

2. Butterfly Valve

This type of water valve has an exterior that can be easily mistaken for a ball valve. However, the internal structure of a butterfly valve is quite different. It features rotating metal discs that effectively manage the flow of water. As water circulates around these discs, the valve maintains control over pressure and flow, even in the open position.

Unlike ball valves, which are known for their binary on/off mechanism, butterfly valves can adjust water flow. One drawback of this type of valve though is that its internal gasket requires regular maintenance. Nonetheless, when seeking residential plumbing services where a valve has to be replaced or installed, the butterfly model can be a primary recommendation.

3. Gate Valve

Gate valves serve the purpose of either completely shutting off water flow or allowing it to flow unrestricted. Using them in any other way may lead to premature damage or accelerated wear. This type of water valve incorporates a metal gate that can be lowered or raised using a circular handle.

Typically found in main water pipes or those leading to the boiler, gate valves are susceptible to corrosion and often become stuck due to their metal component. When this happens, problems such as reduced water flow or a complete blockage can ensue.

To prevent corrosion from developing and ensure that the gate valves are functioning properly, regular maintenance and periodic operation are recommended. In particular, lubricating the stem and gate can help prevent the onset of rust and extend the life span of the valve.

4. Pressure-Reducing Valve

These are plumbing valves designed to regulate water pressure throughout your plumbing system according to your desired level. Equipped with a diaphragm and a spring, this valve type allows you to adjust the pressure to your preferred level.

Also, unlike other valve types which are designed to either open or close the supply of water to your home, a pressure-reducing valve works mainly on reducing the flow of water to decrease overall pressure. It is commonly installed in homes where water pressure is unusually high.

5. Globe Valve

Globe valves possess a distinctive bulge in their bodies, setting them apart from the others. Controlled by twist knobs, these plumbing valves are utilized for regulating water flow, particularly in homes where flow adjustments are frequent.

The design of the globe valve makes it well-suited for outdoor use and utility faucets. By twisting the knob, you can raise or lower the stopper connected to the valve stem, effectively adjusting the water volume to your desired level.

6. Fixture Shutoff Valve

Also known as stop valves, fixture shutoff valves are equipped with small knobs or handles that enable them to have control over water flow for individual plumbing fixtures, such as toilets or faucets. There are two variants of this type of valve —the 90-degree-angle model and the straight version.

Regardless of the type installed in your residential plumbing, stop valves allow you to repair a broken fixture without the need to shut off the entire water supply line. Internally, the valve is known for having a variety of designs, with some utilizing a simple compression washer to control a valve seat that is operated through the handle. Other models employ a diaphragm design that applies pressure to an opening on the valve seat to stop the water flow.

Key Takeaway

As the name implies, residential plumbing valves are commonly installed in residential places. They come in a variety of types, with each one having a distinct feature or a specific function, especially in how water should flow through your home.

Given the diversity of these plumber valves, it can be quite challenging getting them installed on your own. The good news is that you don’t really have to do it because you can simply get a professional plumber who can help you out in choosing and installing the valve that best suits your home needs.
