How to Reduce the Water Pressure in Your HomeIntro:  There may come a time that you feel like there is just too much water coming through the water lines in your home.  Too much water coming through the lines can actually cause lines to blow apart, potentially resulting in a lot of damage.  Each city establishes the water pressure for each neighborhood. This is not something you can change since it is set by the water department in the area in which you live; therefore, you are not actually reducing the water pressure.  Instead, you are reducing the amount of water flowing through your lines. (This has been drilled into my head by my husband, who has been a plumber for over 40 years.)  However you want to phrase it, though, you can reduce the pressure/flow yourself.

Step 1:  The first thing you should do is locate your pressure reducer. This is usually located next to the cut-off valve, which can be found where the water line comes into your house.

Step 2:  Adjust pressure reducer. The pressure reducer is cone-shaped with a stem sticking out from the cone. Using a pair of pliers, turn the stem counter-clockwise several times – six to eight times, usually – to reduce the water pressure. Turn on a faucet inside the house to determine if the pressure has been lowered. (Note: If you are unable to reduce your water pressure by adjusting the pressure reducer, your pressure reducer needs replacing.)

Step 3:  If you discover you have no pressure reducer, one will need to be installed. If this is the case, you should call a licensed and experienced plumber. You probably do not have the tools and/or the expertise to install a pressure reducer yourself.


•Most homes do have pressure reducers.


•Installing or replacing a pressure reducer usually does require the services of a licensed and professional plumber.

•Last year, the city in which I live sent out notices stating that they would be raising the water pressure in our area and recommending that any house that did not have a pressure reducer should have one installed.  If something similar ever happens in your area and you do not have a pressure reducer, I highly recommend that you have one installed.
