Grohe shower will not keep constant temperature

[yvonner]

I have had a Grohe Grohmaster shower which is fed from a Combi Miser Mersey and is part of a Exquisit shower for the last two years with no problems at all.

Suddenly it has decided not to work properly. It alternates from hot water to cold (after about 30 secs.)

The plumber has told me it needs a new cartridge (he hasnt been to see it and wants £70 to visit and verify this - on top of the cost of a new cartridge...).

The shop where it was bought has told me it is because of the hot weather......can you believe that???

Does anyone have any other ideas and if it is a new cartridge how do I fit it myself??

Try a different plumber they dont all charge for callout.

it could well be the cartridge. If u are happy to take on fitting a new one i dont think they are that expensive.

Try ringing grohe for parts

as for the merchant saying its the hot weather, well he works in a merchants........nuff said
