4 Common Causes for Low Water Pressure and How to Fix It

Posted November 2, 2011

The causes of low water pressure are many, from simple fixes to more complex water supply problem. The following are some helpful tips to diagnose and fix some of the most common causes of reduced water flow.

Check Your Faucet Aerators

Mineral deposits and debris can cause faucet aerators to become dirty over time, eventually restricting the flow of water.  By routinely removing and cleaning your faucet aerator screens you can keep the water flowing freely. White vinegar can be used to dissolve the mineral deposits on faucets and shower heads. Simply submerge them overnight.

Check Your Shower Head

You can find inexpensive, high-pressure shower heads at your local hardware store, and that could be all it takes to make your shower flow better. If your shower head has a low-flow fixture in place, try swapping it out with a regular shower head fixture to increase the flow of water.

Check the Water Supply Valves

If someone in your home has turned off and then turned on a water supply valve in your home recently, it may not have been returned to the fully opened position.

Advanced Solutions For Low Water Pressure

If you've checked the techniques above to increase your home's water pressure with little success, ABC can help with more problematic water pressure problems. One solution is a home water pressure booster. A water pressure booster is simply a water pump that works with your home's existing water supply to increase water pressure. ABC can also help find more serious causes of low water pressure problems. If you have a water pipe that is leaking, it will affect the water pressure in your house significantly (while raising your water bill). Try turning off the water supply both inside and outside your home, then check your water meter. Check the water meter once more a couple hours later to determine if the water usage has increased. If so, you probably have a leak that needs to be located and repaired. Another option is to increase the size of the main pipe supplying water to your house. See if you can determine what type of water pipes you have in the home and running to your water meter. Pipe size is an important factor in the amount of water pressure you'll get in your home. The larger the pipes, the more the water pressure, so you may want to consider increasing the size of the main pipe servicing your house.
