It may seem like a pain to test your fixtures after each tiny adjustment but these small adjustments can make a lot of difference in the pressure.
Adjusting water pressure valve regulator.
To set your water to your preferred pressure you need to adjust the pressure regulator valve.
The regulator controls the flow of water through your pipes to your showers and faucets.
You can increase or decrease the water pressure by adjusting the regulator valve outside your home.
Step 2 find the valve.
Increasing water pressure too high can cause older pipe fittings to loosen break or leak.
See the illustration at the top of this page and at left.
Test your pressure after each incremental turn by turning on faucets and shower heads and flushing toilets.
The adjusting nut on a water pressure valve is a left hand nut.
Step 1 locate the valve.
How to adjust the psi on a water pressure reducing valve.
The pressure regulator valve is usually located on the water supply line either in your basement or crawlspace or in the box with your water meter.
It is a fairly easy process that has big results.
The home water pressure regulator reduces the amount of water pressure entering the home from a municipality.
Decreasing water pressure saves water and reduces your water bill.
Too much pressure can damage your pipes and lead to leaks and water waste.
Turning it clockwise increases water flow and counterclockwise decreases water flow.
Step 3 adjust the screw.
If you didn t have a pressure reducing valve installed between the municipal water system and your house the water pressure would break.
Make sure that your supply line has sufficient pressure before adjusting the pressure valve itself.
The valve is made of brass and has a bell shaped midsection with a medium sized screw at the tip.
Depending on your location and distance from the municipal water source incoming pressure can range from 80 pounds per square inch psi to 150 psi.
A water pressure regulator or pressure reducing may be installed.
Once you have found the water meter locate the valve.
