Does my home need a water pressure regulator?

A pressure regulator, also known as a Pressure Reducing Valve (PRV), is a plumbing device installed on the incoming water supply to your home. The purpose of the regulator is to control the water pressure coming into your home from the municipal supply. The incoming water pressure must be high enough to provide adequate flow to all of the fixtures in your home, but not too high. Over time, excessive pressure wears out your plumbing system and everything connected to it, such as water heaters, washing machines, faucets, dishwashers, toilets, and so on. A properly functioning pressure regulator reduces the incoming water pressure to a safe level and is the first line of defense against high water pressure.

Water pressure regulations
Most plumbing systems in the U.S. must comply with the Uniform Plumbing Code (UPC), which allows a maximum water pressure of 80 pounds per square inch (psi). If the municipal water supply exceeds 80 psi, the UPC requires a regulator be installed and the pressure reduced to 80 psi or lower. 50-60 psi is common on most systems.
How to determine the water pressure in your home?
​
It is important to recognize water pressure changes depending on the many factors such as the municipality, location, amount of people using water, temperature, and condition of your plumbing system. Pressure often goes up at night when less people are using water, potentially putting your system at risk. Some ways to check your water pressure are listed below.

#1 Use a pressure gauge.

• Purchase a pressure gauge at a hardware store.
• Attach the gauge to an outdoor hose bib.
• Turn on the water and read the dial on the gauge.

#2 Consult a Plumber
A plumbing professional can check your system water pressure using a pressure gauge. A reputable plumber may open and close valves on your system to get a thorough and accurate reading of the pressure at that time of day. Typical cost for an initial plumbing service call to check your pressure can range between $75 - $200.

#3 Continuous Pressure Monitoring Device
Install a Don Alarm to continuously monitor your system pressure and alert if the pressure is too high. This device can be installed at any fixture (such as a sink or water heater) and continuously checks your home's water pressure to ensure the safety of your plumbing system. It provides an audible alert when the pressure exceeds the plumbing code limit of 80 psi.

Don Alarm notifies homeowners of a plumbing issue such as a failing pressure regulator, allowing for timely repairs before permanent damage occurs. The Don Alarm Standard (DAK10) is designed for home and light commercial use, and costs around $120. No monthly charges, no app, and no special tools are needed for installation. A small investment to protect one your biggest investment - your home.

​Conclusion
A properly functioning water pressure regulator is essential for maintaining the health and longevity of your plumbing system. By reducing incoming water pressure to a safe level, it protects your home and appliances from the wear and tear caused by excessive pressure. Continuous monitoring of your water pressure helps prevent costly repairs. Investing in a reliable pressure regulator and a Don Alarm provides peace of mind and safeguards one of your most valuable assets—your home.
