SHOWER PUMP REPAIR & INSTALLATION

Pump gone silent, roaring like a jet, leaking into the airing cupboard, or running on and on after you’ve turned the shower off? We repair and replace shower pumps across West London — usually same day — and fit new ones where a gravity-fed shower needs a proper boost.
A shower pump cures poor water pressure at the shower by boosting the hot and cold feed on its way to the valve — turning a weak, gravity-fed dribble into proper shower pressure. When one fails you notice straight away: the pressure vanishes, or the noise becomes impossible to ignore. Most shower pump problems are repairable, and even where a pump is beyond saving, a like-for-like replacement is usually a single visit.
We repair, replace and install every common make — Stuart Turner, Salamander, Grundfos, Monsoon, Showermate and Bristan — across Harrow, Ruislip and the Hillingdon borough, 24 hours a day.

NEW SHOWER PUMP INSTALLATION
If your shower has never had any real force to it, the cause is usually a gravity-fed system with too little head between the cold water tank and the shower. A shower pump fixes that. As experienced shower pump installers, we’ll help you choose the best shower pump for your setup — whether it’s a first installation or a replacement shower pump for one that has failed. The important part is matching the pump to your system:
✅ Positive vs negative head — the wrong type simply won’t work; we check which your system needs before fitting
✅ Single vs twin — twin pumps boost hot and cold together and suit most mixer showers
✅ Bar rating — matched to how much boost you actually want, and what your pipework and shower valve can take
✅ Correct siting — on a stable base, on flexible hoses, with the right feeds, so it runs quietly and lasts
We’ll advise on the right pump before you buy, or fit one you’ve already bought. Get the specification wrong and a new pump is noisy, short-lived or ineffective — which is the most common reason we’re called back out to someone else’s installation.
APPROVED SHOWER PUMP INSTALLERS
We’re approved installers for some of the biggest shower pump makers in the UK. Approved status comes from manufacturer training on selecting, fitting and troubleshooting their pumps — so you get the right pump, fitted right, with the guarantee intact.

SHOWER PUMP FAQS
- How do I fix a shower pump with no pressure?
- Nine times out of ten it’s an airlock. Switch the pump off at the spur, open the shower fully to let the system drain and push the air through, then switch back on. If the pressure doesn’t return, the flow switch or impeller has likely failed and needs an engineer — don’t leave the pump running dry trying to force it.
- Why won’t my shower pump turn off?
- A flow switch has stuck or a non-return valve is passing water back through, so the pump never senses that you’ve stopped. Switch it off at the fused spur straight away — a pump left running against a closed outlet will overheat and fail. It’s a common, repairable fault.
- Why is my shower pump so noisy?
- Some noise is normal, but a new loud rattle or growl usually means worn bearings. A pump mounted hard against the floor or rigid pipework also transmits noise through the house; re-mounting it on a proper base with flexible hoses often makes a dramatic difference.
- Is it worth repairing a shower pump or should I replace it?
- Airlocks, flow switches, seals and hoses are all worth repairing. The deciding factor is the motor and bearings — on an older pump that’s roaring and leaking, a like-for-like replacement is usually the better value, and we’ll tell you honestly which you’re looking at.
- What size shower pump do I need?
- It depends on whether your system is positive or negative head, how many outlets it feeds, and how much boost you want. Getting this wrong is the main cause of noisy, short-lived pumps, so we check your system before recommending anything.
- Can you fit a shower pump I’ve already bought?
- Yes — we’ll check it’s right for your system first, then fit it properly on the correct feeds with the right power supply.
