I have been plagued with running-on, clicking, and pulsing of the Pressure Switch ever since I bought my caravan new three years ago. In desperation I have now bought a Whale Surge Damper to try and alleviate the problem. But the fitting instructions are ambiguous. Does anyone know if the Damper should be fitted between the Pump and the Pressure Switch, or on the tap side of the Pressure Switch? Or should I be removing the Pressure Switch altogether? I just know that one of you clever guys will have the answer! Many thanks. From Grandadboilersuit.
