A shower that has faded to a trickle has a cause, and it is worth finding before anyone sells you a pump. Sometimes the mains pressure has genuinely dropped. Sometimes a valve is part closed, a pressure reducer has failed, or old pipework has silted up. And sometimes the whole house is gravity fed, relying on the height of a loft tank to push water out. We diagnose first, then recommend the fix that actually fits.
What you can expect
- Weak showers and slow taps traced to the cause
- Part-closed valves and failed pressure reducers found
- Shower and whole-house pumps supplied and fitted where right
- Single outlet or whole property, both assessed
- Written quote before any installation
Where pressure problems come from
On the mains side, look at the stopcock and any service valves, which are often found not quite open after decades of nobody touching them, and at pressure reducing valves, which wear out. Old pipework can choke its own flow with scale and sediment. On a gravity system everything depends on head: the vertical distance between the loft tank and the outlet, which is why a bathroom on the same level as the tank will always be feeble. Combi boilers need a healthy mains flow too, or even they disappoint.
How we diagnose it
We compare outlets: one weak shower with everything else fine is a local problem, while the whole house struggling points to the supply or the system type. We check pressures and flows at the taps, look at the valves and pipework we can reach, and watch how the system behaves with everything on and then off. That tells us whether the answer is a repair, a reconfiguration or a pump, and we explain it before spending your money.
Pumps and other fixes
Where a gravity system is the limit, a shower pump or a whole-house pump transforms things, sized to the outlets it will feed; they need space, a decent cold supply and sensible fitting, and we will say if yours is not a candidate. A failed pressure reducing valve gets replaced. Where the mains itself is weak, an incoming-main pump may help and is a bigger conversation. What we will not do is bolt a pump onto a problem it cannot fix.
Frequently asked questions
Why is my shower weak but the kitchen tap strong?
Different supplies: the kitchen usually comes off the mains while bathrooms often run from the loft tank on gravity.
Will a pump fix low mains pressure?
No. Pumps help stored-water systems; weak mains needs a different answer, which is why we check first.
Why is pressure worse in the mornings?
Demand across the neighbourhood peaks and shared mains show it. We fix showers as well as pressure, and trace leaks when low pressure has a wetter cause, across areas such as Homerton.
