Hi
We have a Friedrich Grohe shower powered by a pump in the loft. This has previosuly worked fine, however recently it has started cutting out intermittently. It works fine at very cold temperatures and similarly at very hot temperatures, but when I try and put it at the inbetween warmth, it splutters and seems to cut out.
Would anybody know the likley cause of this. My plumber seems fairly blank and before I let him destroy my tiles etc to replace the shower want to be sure this is the problem.
Many thanks for any help.
