Pressure regulators for water are designed to limit the water flow through the house to lessen the stress upon the plumbing infrastructure. Overly high pressure of water can create a host of plumbing issues. Therefore, it is crucial to keep the pressure in check.

While it’s not required in every plumbing system, using a water pressure regulator could be crucial in situations where the water from the municipal system enters the home with high pressure or a problem with the water pressure.

What Is a Water Pressure Regulator?

The water pressure regulator can be described as a kind of valve that lowers the incoming water pressure to a manageable amount to allow for a home-wide plumbing infrastructure. Water pressure regulators are typically installed when your primary line of water comes into the home right after that valve shuts off the water main.

If water pressure is excessively high, it can result in severe damage to the appliances, faucets, valves, pipes, and plumbing fittings. If the system is secured with a water pressure regulator, it puts less strain on the valves inside appliances and shutoff valves. They are less likely to leak, and the fluctuations in pressure are balanced out.

What Is Normal for Water Pressure?

Most plumbing fixtures are built to function best with around 50 psi (pounds for every square inch). However, it’s not unusual for municipal water sources to reach homes at pressures exceeding 300 or 400 psi. If such forces are frequently present and the strain builds up, it could cause joints to break and faucets and other plumbing fixtures could leak, and the appliances to fall apart.

The clothes washing machines, dishwashers, and other household appliances have built-in pressure regulators. However, the house’s water pressure regulator can still protect these appliances. It can also save all plumbing fixtures and pipes in the home.

How Does a Water Pressure Regulator Work?

Water pressure regulators are brass fittings with a dome shape typically found close to the primary shutoff valve in the area at the point where it is where the water main comes into the home. It typically includes an adjustment screw on the top. Inside the water pressure regulator is an adjustable spring-loaded diaphragm that automatically narrows and widens based on the water pressure entering the valve.

If the water enters the regulator at high pressure, the internal mechanism reduces the diaphragm’s diameter to limit the water flow. This may decrease the pressure to the range of 50 to 80 psi. This dramatically reduces the strain on the pipes and fixtures installed over the valve. However, if the water’s pressure decreases and the diagram is opened so that more water can be able to flow into the valve. A screw for adjustment on the upper part of the regulator may be loosened to raise the tension of the spring inside (thereby decreasing the pressure of water that exits the valve) or reduced so that water flows greater freely throughout the valve (thereby increasing the water’s outgoing pressure).

Do I Need a Water Pressure Regulator?

To determine whether you require a pressure regulator, examine the water level from the water supply for your home. You can purchase simple pressure gauges at your local hardware store or home improvement stores. Install the pressure gauge on any washing machine or hose faucet, and then turn on the cold tap to gauge the water pressure. If it is, a tension between 40-60 psi typically is good, but forces that exceed 80 psi are likely to be causing strain on fittings, pipes, and fixtures.

The water pressure in a city can fluctuate dramatically, with the most frequent increase occurring in the evening when the load overall decreases, so be sure to test the pressure at different times during the day. While trying the pressure, ensure the water isn’t used anywhere else in the home, for example, at the fixtures in your garden or other appliances. Also, you can ask your local water company for advice, and they’ll likely be able to inform you of of the pressure regulator suggested in your community.

Do I Have a Water Pressure Regulator?

To determine if your home has a water pressure regulator, find the point where the water main enters your building, and then locate the main shutoff valve to the house. If you do have a water pressure regulator, it will be put in place directly following an existing shutoff valve.

If you cannot locate your main shutoff valve, where the main line connects to the house, then you must thoroughly examine the garage, basement, or crawlspace to locate the valve. The valves are listed in an inspection report for your home.

Once you’ve found the shutoff valves, you need to check the pipes running downstream of the valve to find a Water pressure regulator. If you cannot locate one following a long search, likely, your house isn’t equipped with a valve to regulate water pressure.

How Long Do Water Pressure Regulators Last?

With a healthy plumbing system, a water pressure regulator will last between 4 and 12 years. However, most manufacturers recommend replacing pressure regulators every five years to prevent any possible harm that high-pressure water can cause to plumbing infrastructure.

If you observe any water hammering or any other type of hammering or notice fluctuations or inconsistent pressure, it could be a sign that your water pressure regulator isn’t operating effectively. Test for water pressure every year is recommended. If the valve’s adjustment screw is is no longer able to alter the water force, the valve is time to change the valve.

Be aware that excessive pressure in the water can put additional pressure on your plumbing systems. It can cause water pipes to leak, faucets to run, water hammers to take place in walls, and, in extreme situations, it may cause burst pipes to cause flooding to your home. Therefore, it is essential to replace a damaged control valve for water pressure as quickly as possible.
