Main Causes of Low Water Pressure in House

Every resident in the GTA has experienced low water pressure in house at one time or another. However, if low water pressure is an ongoing issue, there could a problem with your plumbing. The fix could be very simple or you could need professional help.

Following are the most common reasons for low water pressure. If you need further assistance, you should contact a professional plumber Toronto.

6 Common Reasons for Low Water Pressure in House

Shutoff Valve

One of the easiest ways of how to fix low water pressure in house is to check the water shutoff valve, which is typically located near the water meter, generally outside your home. Turn the valve counterclockwise and then check to see if the issue has been resolved.

*NB: Should you ever have any issues with burst pipes, you should turn off your water shutoff valve straight away.


Inspect your home for leaks, especially near the plumbing fixtures, behind counters, and appliances. In addition, you should inspect the toilet, faucets, shower heads, and beneath any sinks.

If one of your toilets is constantly running after flushing or if you have noticed that the water level is lower than usual, you might need to replace part of the tank components. This can prevent your toilet from overflowing or a pipe from bursting, which can be quite a mess as well as costly to repair.

Inspect the leak indicator on your water meter. Additionally, you should make notes of the levels and inspect them again in a few hours (preferably after not running any water) to see if the number has changed. A drastic change could indicate a leak.

Problems with Hot Water Heater

Inspect every faucet in your home to determine which areas are experiencing low water pressure. Next, inspect your hot water heater to see if the water shut off valve is off. Then check it carefully for leaks or damage. Any repairs should be handled by a professional.

Clogged Aerator Screen

If you are experiencing low water pressure from one faucet only, it could be a clogged aerator screen. All you need to do is to soak the screen in a solution of vinegar and water and replace it!

Issues with PRV (Pressure Reducing Valve)

Is low water pressure a problem throughout your house? It could be the PRV (Pressure Reducing Valve). This is usually located near the main water line outside your home and is shaped like a bell. Turn the PRV clockwise to stop low water pressure in house. If this does not resolve the issue, its replacement could be necessary. Contact your local plumber to do the job properly.

The Issue with City Water Pressure

If you have tried all the above and still experience low water pressure in house, you should contact the water department in your municipality to see if there is a problem with the water pressure in your area.
