Why Is My Water Pressure So Low?
Low water pressure is frustrating and can have several different causes, ranging from a simple fix to something that needs a professional look.
Common causes
- ✓ A partially closed stopcock or isolation valve
- ✓ Limescale build-up narrowing pipework, especially in hard water areas like Swindon
- ✓ A fault with your combi boiler's internal pressure
- ✓ A leak somewhere in the system reducing pressure elsewhere
- ✓ Shared supply issues affecting a whole street, particularly during high-demand periods
Quick checks you can do
First, check if it's just one tap or the whole house - a single slow tap often points to a blocked aerator or limescale in that specific fitting, which can sometimes be cleaned or descaled. If it's the whole house, check your stopcock is fully open and, if you have a combi boiler, check the pressure gauge is within the normal range.
When to get it looked at
If pressure has dropped suddenly, or your boiler pressure keeps falling and needs regular topping up, that points to a leak that's worth investigating rather than ignoring. Our leak detection team can identify whether a leak is behind your pressure problems.
