The best way to reduce a home's water pressure is to use a pressure regulating valve, or PRV. A PRV attaches right to your pipe. A professional technician can install it, and then you can easily change your plumbing's water pressure to the correct psi.
Over time, mineral deposits and debris can build up inside your pipes, restricting water flow. This restriction forces the water to push through narrower passages, increasing pressure and potentially leading to leaks and burst pipes.
Air rises. Open all the faucets, hot and cold lines. Start low and work high. Once you have a steady stream of water, close the faucets. Hopefully, all the air will escape. There may be some residual air that should get removed over time.
If you're dealing with ongoing high water pressure, you should check on your regulator. You may be able to lower your water pressure by adjusting the regulator, or you might need to replace it with a new one.
To reduce high pressure in a home, you'll need a Pressure Reducing Valve ( PRV ). In fact, these are often required by code for pressures beyond 80 psi . These devices do exactly what they say, reducing pressures of up to 400 psi down to a reasonable level of your choosing (most are factory set at 45 psi).
A malfunctioning pressure regulator is one of the primary causes of too much pressure in your plumbing system. This device controls the flow and pressure of water entering your home. If it fails, the pressure can surge, leading to various plumbing issues.
Once you find the main water supply, turn it completely off. Turn all faucets to the 'on' position. Once the water supply is off (you might want to double-check this), turn all the faucets in your home to the 'on' position. This will allow for any trapped air to flow through the water lines.
If your well can't get enough water supply due to drought, the pump system will suck in air as it functions. The trapped air will make its way into your piping and faucets. The problem will persist for as long as the drought continues.
A quick and easy way to increase water pressure is to adjust the pressure-reducing valve, which can be found in your home, usually close to your water meter. If your pressure gauge reading was low, make slight adjustments to your regulator.
Install a pressure-reducing valve
Installing a pressure-reducing valve can regulate and decrease the incoming water pressure to a safe and optimal level for your home. A PRV valve can lower water pressure coming into the home if the municipal water supply has a high pressure exceeding 80 PSI.
This causes damage to essential water pipe joints, fixture heads, and valves. In addition to the failure of such fixtures, high water pressure can lead to pipes bursting when they cannot contain the water.
Water pressure is primarily due to the elevation of storage tanks relative to the elevation of your home. Higher water pressures are in geographically low points (near a creek or the bottom of a neighborhood).
The average cost to replace a water pressure regulator ranges from $300 to $650 for most homes, including labor and materials. However, the cost to install a water pressure-reducing valve can vary significantly depending on your location, the regulator type, and the installation complexity.
When turning the water back on to your house, you must be careful not to let air and water rush back into the pipes too quickly. You should turn the water back on slowly. Open one or two faucets before turning the water back on, then incrementally restore water until you see it freely flowing out of the open fixture.
To remove the airlock, you need to bleed the affected pipe. To do this, turn on the tap closest to the airlock and let the water flow until it runs smoothly. This process will force the trapped air out of the pipe, restoring normal water flow.
The best way to reduce a home's water pressure is to use a pressure regulating valve, or PRV. A PRV attaches right to your pipe. A professional technician can install it, and then you can easily change your plumbing's water pressure to the correct psi.
Use a Drain Pump: A drain pump extracts both air and water from the system to clear the pipes. Open and Close Valves: Sequentially opening and closing valves at different points can help purge air from the system.
If your pressure is higher or lower, then you'll need to install, repair, or adjust your pressure regulator to comply. Adjusting your regulator is easy, as long as it's working properly. Simply tighten the screw down clockwise to increase pressure and counter-clockwise to decrease pressure.
On average, water pressure regulator replacement costs $350 or between $250 and $450. You'll pay an additional $100 to $300 for after-hours, weekends, holidays, or projects with access issues. Also called a pressure-reducing valve, each valve costs $50 to $100 on average, but can hit $200 for most single-family homes.
