Tested, diagnosed, then fixed

Water pressure problems are easy to misdiagnose. A weak shower can be a blocked shower head, a faulty valve, a scaled-up pipe, or a supply problem — and each one has a different fix. Guessing wastes money on the wrong part.

We start by testing the pressure at the taps and at the incoming main, then work through the system: stopcock, pressure-reducing valve, isolation valves, filters, and the pipework itself. Once we know the cause, we quote the fix before any work starts.

This page is about the service — testing and fixing pressure problems. For the background on common causes, see our guide: Low Water Pressure Causes.

We cover Crawley, Horsham, Horley, East Grinstead, Redhill and Crawley Down.

Engineer testing water pressure and checking for leaks in Crawley

Pressure is tested at the taps and at the incoming main before any fix is quoted.

Pressure problems we fix

Low pressure everywhere

Partially closed stopcock, faulty pressure-reducing valve, supply fault, or a restriction in the main pipework.

Low pressure at one tap

Blocked aerator, scaled-up fitting, faulty isolation valve, or a kinked flexible hose on that run.

High pressure

Pressure above safe levels strains washers, valves, and appliance hoses. Fixed with a pressure-reducing valve.

Pressure that surges

Pressure that rises and falls, or banging pipes (water hammer), often points to a faulty valve or an unsecured pipe.

Weak shower pressure

Shower head, hose, valve, or supply fault — diagnosed before parts are ordered.

Booster pumps & valves

Pressure-reducing valves for high pressure; booster pumps or accumulators where the supply is genuinely too low.

How it works

1Call us

Tell us which taps are affected and when the problem started.

2Pressure test

We test pressure at the taps and at the main to separate a supply fault from a fault inside your home.

3Upfront quote

We explain the cause and confirm the price before work starts.

4Fix & re-test

We fix the fault and re-test the pressure to confirm it is back in a healthy range.

Quick checks before you call

Stopcock — is the main stopcock fully open? A stopcock left half-closed after other work is a common cause of low pressure.
One tap or all taps? — if only one tap is weak, clean the aerator and check that tap's isolation valve.
Neighbours — if neighbours have the same sudden drop, it may be a water supplier issue. Check with your water supplier before booking a repair.

Frequently asked questions

What is normal water pressure in a home?

Most UK homes run between about 1 and 2 bar at the taps. Below 1 bar usually feels weak; above 3 bar can strain fittings and cause dripping taps and noisy pipes.

Why is my water pressure suddenly low?

A sudden drop across all taps often means a supply issue or a partially closed stopcock. Low pressure at one tap usually means a blockage, a scaled-up fitting, or a faulty valve on that run.

Can high water pressure damage my plumbing?

Yes. Sustained high pressure strains washers, valves, flexible hoses, and appliance inlet valves. A pressure-reducing valve brings the pressure down to a safe level.

Do you fit pressure-reducing valves and booster pumps?

Yes. A pressure-reducing valve fixes high pressure; a booster pump or an accumulator can help where the incoming supply is genuinely too low and the pipework is in good condition.

How much does water pressure repair cost?

It depends on the cause. Diagnosis plus a valve adjustment or a single valve replacement is usually a single visit. You get a clear, upfront quote before any work starts.
