Water Pressure Regulator

What is a Water Pressure Regulator?

A water pressure regulator is a special plumbing valve that is used to regulate the water pressure entering your home through your water line.

We don’t often think about the plumbing in our home until something goes wrong with it. One of the essential parts of your home’s plumbing system is a water pressure regulator, or sometimes called a pressure-reducing valve (PRV). This valve serves the vital role of lowering the water pressure from the main water line to a safe level for the plumbing fixtures in your home. By reducing the pressure to a safe level before the water reaches your fixtures, the water pressure regulator helps prevent many plumbing issues before they happen.

How Does a Water Pressure Regulator Work?

The typical water pressure regulator is a bell-shaped piece located just past the main water shut-off valve. The regulator comprises a pressure adjustment screw at the top, an internal adjusting spring, and a diaphragm. These pieces work together to either raise or lower the water pressure that enters through the main water line. When the pressure from the main water line is high, the spring constricts the diaphragm to reduce the water flow lowering the water pressure. The opposite effect happens when the pressure is too low. The inner mechanism will retract, opening the diaphragm to let more water through. The ability to adjust the incoming water pressure allows the water pressure regulator to help keep your fixtures and internal regulators working efficiently by reducing the strain on your pipes.

Do I Need a Water Pressure Regulator?

While having a pressure-reducing valve has an essential job of keeping your pipes safe, they actually aren’t always needed depending on where you live. The ideal water pressure for a home is between 60 and 70psi, and sometimes the pressure can be at that level straight from the waterline. If your pressure is consistently at 80psi or higher, you should install a water pressure regulator to bring the pressure level down and protect your plumbing system.

There are a few ways to figure out what the water pressure in your home is. The first is to contact your water company. They should be able to tell you what the average water pressure is for the mainline in your neighborhood is and if you need a water pressure regulator. Another way to figure out your water pressure is to test it yourself using a water pressure gauge. The water pressure of your home can often change throughout the day, so if you test your own water pressure, be sure to do it a couple of times during the day to get accurate results.
