Toilet cistern remove and refit... what seals?

Featured Replies

Our flush valve is leaking, apart from the leak the annoying result is the fill valve pulsing on and off every blinking 2-3 minutes to refill the lost water. Looks like the seal down at the bottom is just letting a trickle of water past constantly.

 

I have identified our flush valve as a Siamp Skipper 45 Dual Flush and to save any hassle I was just going to buy another the same.

 

The valve itself seals to the cistern with a big o-ring, but what about the seal from the cistern to the pan? Are they all the same size?

 

The whole point of getting the same valve is so that I can do the job without needing to strip it down, go and find someone who stocks the bits drive about, come home, fit it and generally spend 3 hours doing something that should take 30mins.

 

So can anyone confirm the anatomy of a toilet?

 

 

generally the gubbins of the unit bayonets into a bottom mounting boss so possibly no need to remove the cistern.

Hmmm - yes I can see that, there are some lugs in there. I might have a look later. If I can do it all from up top that would be good. Maybe I can even find a replacement seal for the valve rather than total replacement!

Bang on - I now have the flush body sitting in the basin, looks like the seal is hard, I can get a new one.
