How To Troubleshoot Low Water Pressure In Your Home

As a homeowner, it’s frustrating to turn on the faucet or shower and find that the water pressure is low. Not only does it make daily tasks take longer, but it can also be a sign of a bigger problem.

However, before calling a plumber, there are a few things you can do to troubleshoot and potentially fix the issue yourself. In this post, we’ll go over about some of the common causes of low water pressure and how you can address them.


Check for Clogs

One of the most common causes of low water pressure is a clogged faucet or showerhead. Over time, mineral deposits can build up and block the flow of water.

To check for clogs, start by removing the faucet aerator or showerhead. This can usually be done by unscrewing it by hand, but you may need a wrench if it’s stuck.

Once you’ve removed the aerator or showerhead, inspect it for any visible debris or buildup. You can also try running water through it to see if the flow improves.

If you notice any buildup, soak the aerator or showerhead in vinegar overnight to dissolve the mineral deposits. After cleaning, reattach the aerator or showerhead and test the water pressure again

If cleaning the aerator or showerhead doesn’t improve the water pressure, there may be a clog further down the line. Check any nearby shutoff valves to make sure they are fully open.

You can also try running water through other faucets in the house to see if the problem is isolated to one fixture or affects the whole house.

Check for Leaks

Another common cause of low water pressure is a leak in the plumbing system. Even a small leak can reduce the flow of water and affect the overall pressure in the house.

To check for leaks, start by inspecting any visible pipes for signs of moisture or damage. You can also check your water meter to see if it’s still running when all the fixtures in the house are turned off.

If you suspect a leak but can’t locate it, you may need to call a plumber to perform a more thorough inspection.

In the meantime, you can try turning off the main water supply to the house and checking the meter again. If the meter is still running, there is likely a leak somewhere in the system.

Check the Pressure Regulator

Most homes have a pressure regulator installed near the main water shutoff valve. This device regulates the incoming water pressure to a safe level for the plumbing system. If the pressure regulator fails or is set too low, it can cause low water pressure throughout the house.

To check the pressure regulator, start by locating it near the main water shutoff valve. It may be a bell-shaped device or a simple valve. Use a pressure gauge to measure the water pressure before and after the regulator.

The pressure should be between 45 and 60 psi. If it’s below this range, adjust the regulator until the pressure is within the recommended range.

If you’re not comfortable working with the pressure regulator or plumbing system, it’s always best to call a professional plumber to make any necessary adjustments or repairs.


Low water pressure can be a frustrating problem for homeowners, but it’s often fixable with a little troubleshooting. By checking for clogs, leaks, and issues with the pressure regulator, you can determine the cause of the problem and potentially fix it yourself.

However, if you’re not comfortable working with plumbing systems, it’s always best to call a professional plumber to ensure the job is done safely and correctly.
