Low Water Pressure – What you need to do

Low water pressure is fairly easy to spot – Maybe you turn on the tap to find that the water only dribbles out, or maybe your shower feels more like a light drizzle than a downpour. Low water pressure is a frustration that no homeowner wants to experience, and when it occurs, you want to get the problem fixed as quickly as possible.

The following checklist and guide will help you diagnose your low water pressure problems and know where to turn to for help.

1. Do a quick home inspection. When you first notice low water pressure, check throughout your home to see if there is any water running. Sometimes, the water pressure will decrease in one part of the house when it’s being used in another. There can be a number of reasons for this and its worth obtaining advice from a professional plumber.

2. Try a hot-cold test. Try running the hot and cold water in the area where you discovered low pressure. If only the hot water is flowing at a reduced rate, the problem could beyour water heater. In this instance, contact a professional plumber.

3. Check the water throughout the house. In instances where the hot and cold water are both low in pressure, check the pressure in other parts of the house. Turn on the shower and the bath and run the taps in the bathroom and the kitchen. If the problem is widespread, go to point 5.

4. Look for leaks. Take a few moments to look for leaks in the area surrounding the affected taps. Check inside cabinets and along the floor. For a second story water pressure problem, you should also go downstairs and check the ceiling and the walls. In the case of a leak, contact an emergency plumbing service for assistance (such as Curve Plumbing and Heating Ltd).

5. See if the problem persists. Sometimes, water pressure changes can be caused by problems in the water main that have nothing to do with your home. Wait one or two hours and then try the tap again to see if there is an improvement in pressure. If the problem is resolved, you likely don’t need the help of a plumber unless the problem returns.

6. When low water pressure is widespread in a home and persists for more than an hour or two, contact your water company. They may be actively performing work in the area that has temporarily caused a drop in pressure, or there may be a problem in your area that has already been reported and is in the process of being solved. For Thames Water there is a useful link highlighting any leaks reported and maintenance works in your area.


7. If the water company can’t assist you with a widespread problem or you have a persistent low-pressure problem from one tap, it’s time to call a licensed plumber.
