I have an Autosleeper Talisman motor home, the water pump when switched on delivers water to all taps but also discharges water out of an overflow. The overflow is a clear pipe on the elbow that takes hot water from the Truma water heater. This elbow has no valve on it. I have replaced the one way valve on the system to no avail. The system is a pressurised one and once up to pressure the pump should switch off, unfortunately it does not. Is the solution a new pump or is there a cheaper alternative.
Thanks for any suggestions.
All the best

Chris

if auto switch does not turn off than possible cause
check if you have on the system non return valve not letting by or auto switch faulty. your pump is working as no need to replace it
