Low water pressure is an annoying problem. A hard stream of water makes a more enjoyable showering experience and makes hand washing faster. A few things can cause low water pressure, so the first step in fixing the problem is to narrow down the cause. Here are a few suggestions to try.
Check All The Water Outlets For Pressure
Determine if low pressure is a problem for the whole house of if the problem is isolated to a particular sink or shower. This lets you focus your efforts on the problem area and gives you a clue as to what could be wrong. If only one faucet has low pressure, you know the problem isn't with a main water pipe that feeds your entire house. Also, if the problem is with the hot water at all your faucets, then that narrows down the problem to the hot water supply lines or the hot water heater.
Clean Or Replace Faucets
If low pressure is in one area only, check the screen at the end of the faucet to see if it's clogged. Unscrew the aerator on the tip of the faucet and check the pressure again. Cleaning the faucet or replacing it could be an easy fix for this problem. If your shower has low pressure, the problem might be a head that's clogged with scale. Soak the head in vinegar and clean all the buildup off of it to see if that increases water pressure.
Check The Pressure Valve
If your main plumbing line has a pressure valve, give it a check. This valve regulates the water pressure coming into your home. It may be set too low. Try adjusting the pressure and also try to determine if the valve is damaged. Hiring a plumber to replace the valve might be necessary in order to restore proper water pressure in your home.
Have The Pipes Checked
If water pressure is low in your entire house, then you know you have a problem with the pipes. However, first, call your water office to see if the city is experiencing a problem with water pressure. If they assure you the pressure is fine, then it's time to consider problems with your water main or pipes. If the pressure dropped suddenly, there might be a leak in a pipe. If the low pressure has developed gradually, the cause might be corrosion building inside the pipes that causes restriction to water flow.
The best way to deal with this issue is to hire a plumber to inspect the water pipes in your home. You don't want to poke around water pipes yourself or you might contaminate your drinking water with rust or cause a corroded pipe to burst. A plumber can examine the insides of the pipes to look for clogs, corrosion, and leaks. Sometimes, low pressure is a result of old and worn out pipes that have to be replaced.
