No water or low water pressure?

If you turn on your taps and find you have no cold water, or very low water pressure, it may simply be because there's work going on in your area. You can find everything you need to resolve the problem below.

Do you have low water pressure? Our troubleshooting checklist will explain the potential reasons why and show you how to increase water pressure in your home.


1. Is there planned work or an incident in your area?

If you turn on your taps and find you have no cold water, or very low water pressure, it may simply be because there's work going on in your area.

If you haven't received a letter or card, you may be having problems with your water pressure because an unplanned incident has occurred, for example a water main has burst.


2. Is your tap switched on and clear of sediment

If there's no work going on, have you checked your stop tap? If you're not sure where it is, it's likely to be at the point where the water enters your property; under your kitchen sink, in your bathroom, or possibly your cellar.

Sometimes, when work is carried out, air or sediment can become trapped behind your internal stop tap. There is a simple procedure which can help to clear this, which you can carry out yourself if your stop tap is accessible.

ActionTurn on your main feed cold water tap (usually under the kitchen sink, in the bathroom or in the cellar). Next, turn your internal stop tap off and on several times, finishing by leaving it in the full on position. You may find the water coughs and splutters a bit, but usually this bring back the water or increases the pressure.


3. No hot water?

Were you looking forward to a long soak in a nice hot bath, but have discovered you have no hot water?

Action: start by making sure your boiler is working correctly - check the power supply first. the pressure gauge should be at one bar. Check to see if the pump is running inside the boiler. It's easy to do, just feel the side of the boiler and you'll be able to tell if it's running or not. Check that the pilot light is on. you may need to relight it, in which case simply check your boiler manual for step-by-step instructions.


Still no water or low pressure?

If none of these suggestions have worked and you still have low or no water pressure, you probably need to contact a local plumber for expert help and advice. You can find a local approved plumber on the WaterSafe website
