How to Fix Low Water Pressure

Starting your morning with a full-pressure shower can be invigorating. If your water pressure is low, it can get your day off on the wrong foot. In fact, low water pressure can affect all of the activities in your home that use water, including:

  • Showering and bathing
  • Washing dishes, both by hand and in the dishwasher
  • Doing laundry
  • Using tap water
  • Drain cleaning and more

Read on below to find out what steps you can take to increase the water pressure from your municipal water supply. 

Why is My Water Pressure Low?

The average in-home water pressure is about 40-45 pounds per square inch (PSI). Low water pressure is less than that. There are a number of common causes of low water pressure. We’ll explore some of the most common causes below.

Low Water Pressure in Just One Fixture

If the low water pressure is associated with just a single faucet or showerhead, the fixture may have mineral deposit build-ups (such as rust, sediment, or limestone). With use and over time, fixtures can accumulate such build-up, which inhibits water flow. 

In this case, the aerator might need to be removed and cleaned first. If that doesn’t work, you may need to have the fixture replaced. A professional plumber can help you to explore different options, especially if you are interested in solutions that are designed to conserve water.

Low Pressure with Hot Water Only

The valves of your hot water tank can accumulate mineral deposits, just as your faucets do. Over time, the build-up can keep the valves from sealing, which can cause leakage. 

If the low-pressure issue is only happening with your hot water, you should have a professional check your hot water tank for signs of leaks. A professional will also know how to remove the deposits safely. 

Too Many People, Too Little Water

If too many people are trying to use water at once, it can cause the water pressure to drop. This could be because other members of your household are using water or it could be because your neighbors are also using water, especially if they are watering their lawns or filling a pool. 

If you notice the low water pressure only at certain times during the day, it may be because your neighbors are also using water and the water supply can’t keep up. If this is the case, you’ll probably have to contact your water supplier and ask what they can do to fix the problem. 

Alternatively, if you notice the issue when an appliance that uses water is running at the same time, then the problem is likely internal to the house. If this is the case, you may want to get a plumber to install a water pressure booster to increase your water pressure. 

A booster uses an electric pump and pressure tank to increase water pressure in your home. It’s an affordable and effective way to solve the problem quickly.

Main Water Valve

If water pressure is low throughout your home, it could be the water main valve is not fully open. 

This valve looks similar to that of your hose faucet. Because the valve isn’t located in the same place for all residential homes, it might be useful to have a plumber help you find it.

The main water valve may be outside, but it also is likely it is inside where the main pipe from the municipal supply enters your home, in the garage, or near the hot water heater. Once you know where the valve is, a plumber can safely ensure it is fully open, whether the connection is a valve or a lever.
