I have a Grohe concealed cistern located in the loft of a low cottage giving very difficult access. The cistern has started a continuous leak into the toilet and every few minutes the cistern is topped-up. What do I need to effect a repair?
I have carried out my own repair successfully as follows:
1. Because of space restrictions in my loft space I removed the complete cistern
2. The plunger actuator assembly is retained by a plastic frame a the top of the tank and this is held on either side by integral clips
3. The discharge valve is a float mechanism which I removed to expose two flexible plastic washer seals
4. There was no evident wear on either seal so I reassembled the cistern and reinstalled it. There was a marked reduction in the leakage rate but it was not cured.
5. I contacted Grohe for replacement seals but these are not sold separately so I had to purchase a replacement flat assembly which I have now fitted and everyting works fine except for a few days of backache
