About this service
Low water pressure in Kingston upon Thames, diagnosed before we recommend anything
Weak showers and slow-filling baths are usually one of a handful of causes: a partially closed stopcock, a scaled aerator, an old gravity-fed system, or genuinely low mains pressure. We measure your actual pressure and flow rate before suggesting a fix — a new shower head won't help a gravity system, and a pump won't fix a scaled cartridge.
Common causes of low water pressure
A stopcock or isolation valve left half closed, scale in taps and shower heads, an undersized or part-blocked supply pipe, a hidden leak, or low pressure in the street main. The first check is whether it affects one outlet, the hot side only, or the whole house.
Low pressure in the shower
On a gravity-fed system the pressure depends on how high the tank sits above the shower, which is why upstairs showers are weakest. A shower pump or a mains-pressure hot water system solves it. See also shower repairs.
Pumps, unvented cylinders and supply upgrades
Options run from a shower pump, to a whole-house booster set, to an unvented cylinder that gives mains pressure at every outlet, to replacing an old narrow supply pipe. We recommend the smallest one that fixes your problem.
Pressure too high?
Banging pipes, dripping taps and a boiler pressure relief valve that keeps letting by can mean the mains pressure is too high. A pressure reducing valve on the incoming supply protects appliances and fittings.

Gravity-fed systems in New Malden, Tolworth and Chessington homes
Many of the 1930s semis in New Malden, Tolworth, Chessington and Berrylands still have a cold tank in the loft and a vented cylinder in the airing cupboard. They work, but shower pressure upstairs is low by design.
In Kingston, Norbiton and Surbiton the more common cause is an old, narrow lead or iron supply pipe, sometimes shared between houses. We test both pressure and flow so you know which problem you actually have.
A sudden drop in pressure can be a hidden leak or a burst pipe. Old, narrow supply pipes are covered on our pipe repairs page. Maxfix is a local plumber in Kingston covering every KT postcode.

Frequently asked
Water pressure FAQs
Would a pump or a new cylinder fix my weak shower?
Depends on your system. Gravity-fed setups (tank in the loft) often benefit from a shower pump; for a bigger, more permanent upgrade, converting to an unvented cylinder gives mains-pressure performance at every outlet in the house.
Is low pressure my problem or the water company's?
The water company is responsible for pressure up to your property boundary. Check the cold kitchen tap, which is fed straight from the main: if that is strong, the problem is inside your home. If it is weak, ask your neighbours and contact your water company.
Will a combi boiler fix low pressure?
Only if your mains pressure and flow are good. A combi delivers whatever the main supplies, so on a weak or shared supply it can make things worse. We measure both before recommending one.
Can I fit a pump straight onto the mains?
Not an ordinary one. Water regulations limit how much you can pump directly from the main. Where a boost is needed, we fit a compliant booster set or a break tank and pump.
