Annoying potterton Combi 80/100 problem

markell · 14 Nov 2006

Can anyone help why my potterton combi boiler looses CH water pressure after the hot water has been run for a while.

When the central heating is on pressure sits happily at 1.5 bar, then after HW is run drops until I top up again... I have repaired a couple of leaks in the CH not sure whether there is more or relevant.

thanks to anyone in advance.
