So in our place all 4 bedrooms have ensuite's and there's 2 WC's downstairs and all 6 use Grohe suspended loo's and associated mechanisms.
These are great and lovely until you need to do any maintenance on the cistern as they are hidden within cupboards which someone else built and left few clues on how to get into them...
My daughter's has been constantly dripping into the bowl for a few days and now I'm off with them for half term it's time to get them helping me with a few household jobs that have been stacking up.
Once I got into the cistern (without getting annoyed and cutting my way in with the multi tool like I did with Barney's, only to instantly realise how easy it was to do without trashing his bathroom...) you remove the flushing mech which look like this...
And when you pull it apart it contains 2 silicone washers like this, that on googling I have learned have a tendency to develop blisters filled with water which create enough of a gap in the seal to cause a small but constant flow...
Now you can prick these and get it working again but they also develop micro blisters that still cause drips but are nigh on impossible to see never mind pop!
Luckily after an hours googling and forum reading (after calling Grohe and being told that the washers are not a sale item and I would need to buy the full flush cylinder for about £75!!) I found a place that sells the washer kits for a few quid each so bought a few spare sets after the downstairs WC went 12 months ago so rather than faff popping and testing I just swapped them out.
The new ones are apparently made of neoprene rather than silicone and don't suffer from the same affliction, so fingers crossed...
Anyway, 30 mins and we are drip free and another job ticked off the list!
Cheers
