How to Improve Household Water Pressure

Household water pressure that is too low can be remedied by a variety of methods. The first step is to check your pipes to determine if the problem is within the household pipe system.

Check the Taps

Low water pressure in the household found only at kitchen or bathroom taps can be the result of clogged screens. Check the faucet screens to make sure they haven’t accumulated mineral deposits from hard water. If they are clogged, the water pressure will be significantly reduced. This can be remedied by replacing or removing the clogged screen.

Check the Hose Bib

Check the pressure at the hose bib, located outside and typically in the front of your house. If the flow is steady at the hose bib, the water pressure problem may be isolated somewhere within the household. If there is very little water pressure at the hose bib, the gate valve located on the standpipe may not be turned up high enough. If you determine that the gate valve is turned up all the way and the water pressure is still too low, the pressure regulator may need replacing.

Household Water Pressure Regulators

Most household water pressure regulators are adjustable but are typically set between 50 and 70 psi. This is normal water pressure for household use. These regulators are always located above the ground, usually where the pipes enter the household. They are shaped like bells and installed next to the hose bib.

It is recommended that a professional plumber make adjustments to the water pressure regulator. Adjusting it incorrectly could cause your water pressure to become too high or too low. However, in an emergency, you can check the regulator to make sure it is set properly. Never set it any higher than 70 psi.

To adjust the household water pressure regulator, first loosen the lock nut on the stem. The stem is located on top of the bell-shaped regulator. Next, rotate the stem clockwise to increase pressure and counter-clockwise to reduce pressure. To be sure, you aren’t setting the water pressure too high or low, consider turning a garden hose or lawn sprinkler on while making the adjustments. You can then observe the changes in water pressure as you work.

If this process does not improve your household water pressure, the services of a professional plumber may be needed. Use caution when working with your household water pressure regulator and do not deviate from the instructions above unless you are experienced.
