britanny combi se

[nathan25]

hi just wondered if anyone can help

i have a brittany combi se (unfortuanatley), there is a leak from where the motor sits on top of the 3 way port valve, i have replaced the valve and the housing it sits in, however its still leaking, it only seems to leak when the hot tap is turned on, could it be coming from the motor at all??

thanks

nathan

If you mean the Britony Combi 80 or 100 SE, the 3 way valve is controlled by a diaphragm which is in the unit above the valve itself. The diapragm pushes a pin downwards when the water pressure changes upon switching a hot tap on, pushing the valve downwards. I remember there is a rubber o ring which stops water from leaking around the pin - might be letting water by?
