Water pressure regulators need replacement about once every 4 to 12 years. While some PRVs may last longer than others, manufacturers recommend swapping out your regulator at least once every 5 years to prevent damage. Your home will show signs when your regulator may be failing.
How do I know if my pressure-reducing valve is bad? Thumping, banging, hammering, or vibrating noises in the walls… High water pressure, water leaking from faucet, toilet running constantly…
However, most manufacturers recommended replacing water pressure regulators about once every five years to limit any potential damage high water pressure could have on the plumbing infrastructure.
What are the most common reasons a pressure regulator fails? The most common reason for pressure regulator failure is age. Over time, the regulator experiences stress from pressure fluctuations. It also experiences decay.
Water pressure regulator replacement: $250 to $1,000. Pipe section replacement: $500 to $4,000.
Normal psi for a home pipe system is between 30 and 80 psi. While you don't want the psi to be too low, it violates code to be above 80. Instead, you should aim for a psi that's between 60 and 70.
Some of the first signs of a failing pressure regulator are a leaking water heater or commode. The water coming from a faucet may also exit with such force that splashing or water “hammering” may occur.
These mineral deposits accumulate inside of the valve body, leading to lower-than-intended home water pressure. In most cases, a plumber can resolve this issue by disassembling and cleaning out your regulator valve. Soaking the valve in a calcium and lime remover loosens up and dissolves unwanted mineral deposits.
Excessive noise: If your hot water heater is rattling or emitting a high-pitched whistling noise, it's likely the sound of steam trying to escape the tank, which is a sign of far too much pressure pressing against the inner walls. This means the relief valve isn't doing its job and may need replacing.
Regulators must be subject to regular inspection and replaced every 5 year for non-corrosive gases. The body of the regulator is stamped for date of manufacture.
When a pressure regulator fails, it could cause a sudden increase or decrease in water pressure. A common reason for failure is sediment build up in the valve, which could cause blockages, pump problems, and short cycling.
To check a pressure regulator, release compression on the regulator spring by turning the adjusting knob counter-clockwise to open the outlet valve. Adjust the pressure regulator to approximately 80% of inlet pressure showing on the receiver side of the shut-off valve.
With the right tools, you will be able to adjust the water pressure regulator by yourself instead of calling in the plumber. Here's how you go about the job. The first step is to locate the water supply line that supplies water to your house. Once you have located the line you will be able to find the water meter.
The price of pressure reducing valves starts at around $50. You can expect to pay around $350 for a professional plumber to install a new pressure reducing valve.
If your pressure is where it needs to be, then you're good to go! If you need to make a few more adjustments, turn the tap off and use your wrench to tighten or loosen the adjusting bolt again.

You can recognize it as a bell-shaped component attached to your exterior pipes. This device is necessary because many water supplies leave the city's pipes at a higher pressure than you want to flood through the incoming water lines of your home.
While pressure-reducing valves reduce or limit incoming pressures, pressure regulators maintain constant outlet pressures regardless of upstream or downstream fluctuations.
The pressure level can vary, but 60 PSI (pounds per square inch) is recommended for most residential homes. Water pressure should not be higher than 80 PSI. Anything higher can cause major appliances, including water heaters and toilets, to stop working properly because of the stress on plumbing and other parts.
Water Pressure Readings
Normal water pressure is generally between 40 and 60 PSI. Most homeowners prefer something right in the middle around 50 PSI. Once you measure the water pressure in your house, you can adjust it to a setting that is ideal for all family members and household uses.
Normal water pressure range
In general, residential water pressure ranges between 45-80 psi (pounds per square inch). If your water pressure is under 40 psi, it's considered low. A psi between 20-30 is considered very low, and under the minimum water pressure required by most building codes.
If the water pressure level coming into your home from the city exceeds 80 psi, you need a water pressure regulator. Reducing the system pressure 10 to 20 psi can save thousands of gallons a year in the typical home.
