How to Troubleshoot Low Water Pressure

Low water pressure can seem to be a minor inconvenience, but knowing when it is time to call your plumber is crucial in preventing any costly and long-term damage. Below, we are sharing five strategies to determine the source and severity of your low water pressure.

1. Check All FaucetsShutterstock 1475908106

Test multiple taps in your home. Note whether water pressure is low for hot and cold water. If water pressure is low for just your hot taps, you may have a water heater issue, and a professional inspection can pinpoint the exact cause.

However, if water pressure is low in all hot and cold taps, check with your neighbors to see if they’re having the same problem. If so, there could be a problem with your main water line, and you’ll need to contact your water supplier.

2. Check Your Aerators

If the problem was with one appliance, there may be a clog in the faucet or aerator. Remove your faucet and aerator to clean out debris.

3. Test Your Pressure Reducing Valve (PRV)

If water pressure is low in one tap but your aerator is clear, look for your PRV. It’s a bell-shaped part connected to your water line where it enters your home. Make small clockwise adjustments to see if pressure increases.

4. Check Your Shut Off Valve

If all faucets have low pressure, check your main shut off valve. If the problem is with one faucet, check the fixture shut-off valve. They may be partially closed and causing low water pressure.

5. Look for Water Leaks

Sometimes leaks may be from broken or worn O-rings, cartridges, or stems. These issues can typically be fixed yourself. However, if you notice pooling water in your basement, soaked drywall or large wet spots in your yard, you’ll need to call a plumber.

While minor plumbing problems can easily be fixed yourself, certain issues may be a sign to call a plumber. Our team of certified plumbers at Thompson Family Plumbing & Rooter Inc. is here to help with all your plumbing needs from drain cleaning to sewer services, and more.
