5 Common Problems That Cause Low Water Pressure in Your Home

This article details 5 common reasons for a drop of water pressure in your home.  

The inlet valve to your home should have an average water pressure in the range of 40-50 psi. Check this first. If the pressure is low you may have to contact your utility’s company

Here are 5 common problems that are likely to occur.

1. An Off or Partially Closed Water Meter Valve/Main Shutoff Valve

First, check the water meter valve if it is fully open. Next, check your home’s main shutoff valve that is typically located near the foundation wall where the main city supply pipe enters your home. Check whether it is fully open or not.

  • Gate Valve: If is a gate valve, the handle must be fully turned in the counterclockwise direction
  • Ball Valve: Make sure the handle is parallel to the pipe direction.
    Oftentimes, this main shutoff valve can be left slightly closed after some repair work.

2. Water Main Leakage

Check the ground around the garage or basement where the water main enters your home.If you notice water, it may be due to a leak in the  main water line.

Another related cause can be a leaking pipe. It is important to find the leakage point and fix it quickly to prevent water damage. If you suspect a leak, the water should be turned off and you should call a licensed plumber.

3. Buildup of Rust

Do you have steel galvanized plumbing in your home? There is a good chance the water pressure has fallen due to rust buildup. Such plumbing is prone to corrosion, leading to a fall in water pressure until it is fully blocked. If this is the cause, the plumbing will have to be replaced.

  • This can be an expensive problem to fix
  • The buildup takes years and the drop in water flow is usually gradual
  • Re-piping the system with the latest water supply piping is the only solution

4. Check the Water Pressure Regulator

Not all homes have water pressure regulators. If you are unable to determine any other cause of the problem, check whether there is a regulator installed by a former homeowner.

The function of these devices is to limit the water pressure transferred from the city pipes. If the regulator has issues, it can cause sudden changes in water pressure.

5. Problem with a Shower head or Nozzle

If the water pressure is low only in a single shower head, it may be due to a block in the head. Mineral deposits over time can build up and cause the tiny spray holes to clog up. If you have low water pressure at a single faucet, it may also have been caused due to mineral buildup. Remove the nozzle, run the water, and check for pressure. If the pressure is normal without the nozzle, replace the nozzle.

These are some of the most common causes of low water pressure in your home. If you are unable to determine the cause or fix the problem, feel free to call A Clear Choice Plumbing & Heating at 720 938 1554. We are available around the clock to handle all kinds of plumbing issues.
