The call-out
The call-out was for faulty pumps in a pump chamber.
The repair
The engineer suspected that the non-return valves had failed. The pumps were removed and reinstalled free-standing on 40 mm pipework, with new non-return valves and a new shut-off valve.
Result and next step
Water now pumps away, but it is very slow. The engineer suspects further problems down the line from the chamber. The outlet from the chamber is a flexible hose.
Controls
The photographs from the visit include the pump control panel.
