Question

Hi when on holiday water stopped suddenly from all taps, pump works when tested but pump running light not coming on at zig unit have checked all fuses and got new leisure battery now run out of ideas

Answer

Have you checked that the pump is actually delivering water when running. If the rotor in the pump has become detached then even though the pump will run, it will not deliver water. If the pump is OK then you may wish to look at the non-return valve at the water inlet to see if it has become stuck in the closed position.
