Water Pressure

What to do if you have a problem with water pressure

Try these simple checks before contacting us:

1. Speak to your neighbours
   If their pressure is also low, we may be working on the network. If not, the issue could be with your internal plumbing.
   
   
2. Check for work in your area
   Planned or emergency work can temporarily affect pressure.
   Use our work in your area map to see if we’re working nearby. 
   If we’re not, continue with the checks below.
   
   
3. Check for frozen pipes
   Cold weather can freeze pipes and reduce pressure. Look for frost or condensation.
   
   Find out how to protect pipes from the cold weather. 
   
   
4. Check your stop tap
   Turn the stop tap off and count how many turns it takes. Run a nearby tap until the water stops. Turn the stop tap back on using the same number of turns. Repeat this a few times to see if your pressure improves.
   
   Need help locating your stop tap? If it’s stuck or broken, contact a qualified plumber.
   
   
5. Run your cold kitchen tap
   If this tap works fine but others don’t, it’s likely an internal plumbing issue. You’ll need a plumber to investigate further.
   
   
6. Try a quick flow test
   First, turn off all taps and appliances. Fill a 1-litre jug or bottle with water from your cold kitchen tap. If it fills in under 7 seconds, your flow is fine. If it takes longer, your water pressure might be low.
   
   
7. Look for leaks
   Leaks can cause pressure to drop. We’ll fix leaks outside your property, but anything inside is your responsibility.
