Common Causes of Low Water Pressure in Faucets & Showers

General Plumbing Tips

Water pressure problem can be common in homes and many homeowners tend to live with it without getting it fixed. Your faucets can take forever to fill the bathtub, the shower may not be as effective as it used to be, the washing machine may require more time to complete cycles. There are many reasons why you may be having this issue.

Water Meter Valve
The first thing you should do is to check the water meter valve, if it is fully open. If there has been some recent work in the plumbing, it is likely that the water meter valve may have been left slightly off. This valve can be usually found on your home’s outside wall. In some homes, it may be found in the garage or basement.

Main Shut-Off Valve
This is the second valve that controls water supply to your home and is mostly located on the inside. Check it and ensure that it is fully open.
• Gate Valve: The handle should be turned counterclockwise to its full extent
• Ball Valve: This type of main shut-off valve should have the lever handle parallel to the pipe’s direction
The pressure may be low because it has been left closed after some repair.
Other Common Causes
Some of the other common issues causing low water pressure include the following:
• Faulty Fixtures: The faucets or shower head may have become old and got clogged with mineral deposits, dirt, or rust.
• Clogging in Pipes: If it is not all the above-mentioned problems, the issue may be due to clogging in pipes. This happens in case you are using old galvanized pipes or if the pipes are too old.
• Pressure Regulator: A faulty pressure regulator may also be the cause of water pressure issues.
Any corrosion in the plumbing can also cause water pressure problems. If the root cause is not related to the valve, you should call your plumber to find and fix the underlying issue.
