Soaking the valve in a calcium and lime remover loosens up and dissolves unwanted mineral deposits. After rinsing the components clean, the plumber reassembles the valve, which should now function without undue restrictions. Pressure regulator valves come in two main styles: direct acting and pilot operated.
Pressure reducing valves, like most components in your system, are subject to water quality and repetitive use. They should be inspected and cleaned at least once every 12 months.
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.
Another common cause of pressure regulator repair is rust. Exposure to moisture can cause the components to rust over time. Eventually, the rusting becomes so severe that the part can no longer function properly. Excessive pressure can also cause the pressure regulator to fail.
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.
Water pressure regulator replacement: $250 to $1,000. Pipe section replacement: $500 to $4,000.
If the water pressure regulator is not adjusted properly, you could have either too much, or too little pressure in your faucet or shower. With the right tools, you will be able to adjust the water pressure regulator by yourself instead of calling in the plumber.
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.
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.
Normal water pressure is generally between 40 and 60 PSI. Most homeowners prefer something right in the middle around 50 PSI.
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.
How long will a Water Pressure Reducing Valve last? The life expectancy of a water pressure regulator is most commonly in the range of 10 to 15 years. However, you may see a regulator malfunction at three years and one still properly functioning at 20 years old if regularly maintained.
A pressure reducing valve (PRV) is an important part of your plumbing system, as it helps regulate the water pressure in your home. If a PRV fails and the pressure in your pipes gets too high, it can cause all kinds of problems, from plumbing fixtures failing to appliances leaking and more.
The ideal water pressure for a house will be somewhere in the range of about 45 to 65 psi. Anything higher than 80 psi can cause damage, and anything much lower than 45 psi may result in issues when you use your shower, toilet, dishwasher and other water-consuming appliances.
Temperature changes – As the temperature increases in your plumbing system, water will expand and pressure will increase. This can occur as water is heated by the water heater, especially if it has a defective expansion tank or pressure relief valve.
On top of the regulator should be an adjustment screw and a lock nut. The adjustment screw raises and lowers the water pressure, but before it can be adjusted, you need to loosen the lock nut below it. Loosen the lock nut by half a turn with the crescent wrench.
Building code requires that homes that receive water with pressure greater than 80 PSI have a water pressure regulator. A home's water pressure should stay in the range of 40 to 60 PSI.
Pressure Relief Valve – $20 to $200
If you notice that the valve is consistently leaking, it may mean that the tank's pressure is too high, or you might simply have a faulty/clogged valve. The cost of a new pressure relief valve is about $20, and repairs may total to $200.
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.
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.
