How to Adjust a Water Pressure Regulator

A water pressure regulator checks the high pressure water flowing from a huge public water supply line to enter your household pipe-line. In case the regulator does not function properly, it will lead to water leakage from pipes, faucets and may also lead to bursting of pipe lines. If the street side water pipeline has an old regulator installed on it, then on your domestic end, you install a new water regulator so that it adjusts the water pressure. Even the local governance body of your vicinity would want the water pressure regulators to be installed at your end, so that there is no damage caused to pipelines or plumbing arrangements at your home. However, you still need to make some adjustments with the water regulator sometimes. Read the following instructions to learn how to adjust a water pressure regulator.

You just need an Allen Wrench and screwdriver for adjusting the water pressure regulator. If there is any leakage, you might need to make some replacements. Check for these before you start working. If you happen to change some valve or pipeline, you cannot rush to get it at the 11th hour. Try to get it and your home will be full with water. Collect all the material and equipment before you begin adjusting the water regulators.

How to adjust water pressure regulator?

  • Before trying to make any major adjustments, try to adjust the water pressure by the screw on the regulator.
  • Turning the screw in clockwise direction will increase the pressure of water in your home.
  • Turning the screw in anti-clockwise direction will decrease the water pressure in your home.

If this does not help, you adjust the water pressure regulator then you need to make further adjustments. The procedure for adjusting the regulator is given below.

  • Firstly, you need to note the reading of your water pressure regulator. For this, attach a water pressure gauge to a faucet on the pipe. The standard reading for the water pressure in domestic households is 40-60 psi (per square inch)
  • If the readings are not within these set standards, then you need to adjust the water pressure.
  • Find out the regulator of water pressure in your household plumbing fittings. On this water regulator, there is brass valve, which has a bell-shaped housing.
  • On the top of this bell, there is a lock nut and a screw, which will help you adjust the regulator.
  • The wrench should be adjusted such that it holds the lock nut properly. With a screwdriver, hold the screw in place. Move the wrench to unscrew the lock nut. Do not loosen the nut completely, just a little.
  • While loosening the lock nut, the adjusting screw needs to be turned by one turn in clockwise direction if the noted reading of water pressure was below 40 psi.
  • If the reading was above 60 psi, then turn the screw by one turn in anticlockwise direction.
  • Now again check the reading on the water pressure gauge. Check if the reading is between 40-60psi. If not, then readjust the pressure by turning the lock nut and screw.
  • Once you get the required reading, hold the screw in position, and fix the lock nut properly.
  • Check for water pressure in all the different connections in your house. Check it twice, thrice and also check the reading on the water gauge.
  • If the reading remains constantly in an acceptable range, then the water pressure regulator is adjusted correctly.

Adjusting the water pressure regulator in a water heater:

Another water pressure regulator which needs to be adjusted is the regulator on the water heater. There is a valve on the water pressure regulator, which as gets old starts leaking and indicates that it needs to be replaced or repaired. However, the valve may not function correctly, if the water pressure is not proper. You need to adjust this valve, which serves as the water pressure regulator in a water heater.  Given below is the procedure for adjusting the water pressure in a water heater.

  • Before making any changes or adjustments with your water heater, first switch of the electric current to it.
  • Turn off the cold water supply to your water heater.
  • Using an Allen wrench relieve the valve completely and detach it.
  • Now the new valve’s thread needs to be wrapped in the plumber’s tape, and screw the valve to the water heater again. Using a wrench, tighten the valve completely.
  • Now turn the cold water and power on. The pressure of the water will be back to normal now.

Any problems with the water pressure next time in your house I am sure you can easily adjust it yourself and would not need a plumber to fix it.
