The Tank And Pump Problems We Fix
Find yours below. Whatever it is, you get a fixed price before any work starts.

Tank Pumps
A tank pump that has stopped working, checked on site and replaced when it has failed, including a pump you have bought yourself.

Tank Filters
A cracked or leaking filter on the line from the tank, replaced with a new filter and canister.

Leaking Tank Pipework
Drips at the tank tap, valves or fittings, and leaks in the pipes running back to the house.

Toilets Not Filling
Toilets or the laundry on tank water that have stopped getting water, traced back from the cistern to the tank.

Old Tank Removal
An unwanted tank drained, disconnected and taken away, with the pipework capped and the house back on mains water.
Common Rainwater Tank And Pump Faults
Three ways a tank system fails. All three end the same way: found, fixed and tested, with the price agreed before we start.

Burst Pipe At The Tank
Water spraying from a split pipe or fitting at the tank needs stopping now. Close the valve at the tank, or turn off the water at the meter if the leak is on the mains side, and call us.

Pump Stopped, No Water
The pump will not start, or the toilets and laundry on tank water have stopped filling. Check the pump has power and the tank has water, then book us to find the fault.

Slow Drip Or Old Tank
A slow drip at the tank tap or a fitting, or a tank you no longer use, can wait for a booked visit. We fix the leak or take the tank away, with the price agreed upfront.

Rainwater Tank And Pump FAQs
Answer:
It depends on what has failed. A leaking tank tap or fitting is a small job, while a new pump costs more and the price depends on the pump and how much pipework changes. Either way you get one fixed price before we start.
Answer:
Check the simple things first: that the pump has power, that there is water in the tank and that the filter is not blocked. If it still will not run, the pump or its controller may have failed. We test it on site and tell you whether it can be fixed or needs replacing.
Answer:
Yes. We fit the pump you have supplied to your existing pipework and test it before we leave. Check it suits your tank and what it needs to supply, or send us a photo of the setup and we will tell you.
Answer:
Toilets and laundries on tank water stop filling when the tank is empty, the pump has stopped, or the switch that changes them over to mains water has failed. Check the tank level and that the pump has power first. If they still will not fill, we trace the fault from the tank to the cistern.
Answer:
It changes the toilets and laundry over to mains water when the tank runs low, so they keep working in dry weather. When the switch fails, the fixtures it supplies can stop getting water. We replace a faulty switch, or take the system out and connect the house straight to mains if you no longer want to use the tank.
Answer:
Leaks often come from the fittings rather than the tank itself: the tank tap, an outlet fitting, a filter or a valve, and those can often be fixed on the spot. A crack or split in the tank body is a different problem, and we will tell you on site what your options are.
Answer:
Yes. If you have bought a tank, we connect it: the downpipes into the inlet, the overflow, and the pump and pipework to whatever it will supply. Tell us where the tank will sit and what you want it to run, and we will quote the connection upfront.
Answer:
Yes. We drain and disconnect the tank, take it away, cap off the old pipework and reconnect anything that ran on tank water to the mains. Downpipes that fed the tank are redirected to the stormwater.
