4 Common Causes of Low Water Pressure

Posted on: 28 November 2016

When you turn on a faucet or the shower, you expect water to flow out, so a drastic change in water pressure can be quite alarming. There are several things that can cause low water pressure in your home, and most problems have easy solutions. Some common causes of low water pressure include the following.

Faulty Pressure Regulator

A water-pressure regulator is a small device that is usually found around the front hose connection of your house. This type of regulator is typically preset by the manufacturer, so homeowners don't have to worry about making adjustments. But over time, a pressure regulator can fail, and this can lead to low water pressure in your home. If you have a problem with low water pressure, have a licensed plumber check your pressure regulator and replace it if needed.

Leaking Pipes

When a pipe inside your home is leaking, water pressure can drop. Unfortunately, sometimes leaks can happen in pipes that are hidden behind walls, so homeowners may not even be aware of the problem. If you suspect that the water-pressure problem in your home may be due to a leaking pipe, try turning off all faucets and water taps inside and outside your home and then reading the number on your water meter. Leave the house for a few hours, and check the meter when you return. If the number on the meter has increased, you probably have a leak somewhere in your plumbing and will need to call a plumber for repairs.

Mineral Deposits

Tap water has minerals in it, and after many years these minerals can begin to deposit on the pipes in a house. When mineral deposits get too large, they can block the flow of water through a pipe and create a low–water pressure situation. Mineral deposits tend to be more common in homes that are several decades old and homes that have galvanized iron pipes. If you have large mineral deposits in your pipes, a plumber will need to replace sections of your plumbing with new pipes.

Peak Water Usage

If you experience low water pressure intermittently and around the same time each day, this may just be caused by the fact that the time is a peak water-usage time in your neighborhood. If possible, try re-arranging your schedule in order to utilize the water coming out of the tap at a time when other people are not likely to be doing so.
