When your city-supplied water has lost pressure, there are several things that could be causing the problem. Here, you'll find a few things to check to determine what could be causing the loss of water pressure throughout your home. This can help you determine if you need water pressure repair.
Exterior Water Shut-Off Valve
The first place to look is the exterior water shut-off valve. Sometimes, the valve may not have been opened entirely, which can reduce the pressure that you see in the home.
To find the exterior shut-off valve, go to the area where the meter is installed. Turn the valve all the way to the left; this shuts the water off. Now, turn the valve about 90 degrees in the opposite direction. This will open the valve fully and allow the water to enter the home at full pressure.
Sometimes, the exterior shut-off is located under an access panel on the ground. If this is the case, you may need a wrench to shut the water off and then turn it back on. Use the same process as above to restore water to full pressure.
Interior Shut-Off Valve
Inside your home you'll find a second shut-off valve. There are different types of valves used in homes, so how you open and close it will be determined by the type of valve your system is equipped with.
If the fixture is an older gate valve that has uses the washer and rising system, it could be malfunctioning. It may look as if the valve is fully opened, but the inner elements are not opening the whole way and are restricting the flow of water.
If all of the valves are open fully and your water pressure is still low, there could be a blockage in the line somewhere. If you have done any yard work that required digging in the area of the water line, you could have crimped or crushed the line. It's also possible that if a heavy car was driven over the line, that it could have pinched it off.
If you cannot find the cause for the loss of water pressure in your home, contact your local expert. He or she will know exactly what to look for to get the water flowing in the home the way that it should. Ignoring the problem could end up costing you more money in repairs as your appliances won't function properly and will begin to break.
