Had a leak in the cold water inlet pipe a month and a half ago. Insurance dragged their heels and I finally gave up and decided to do it myself. Bath is in nice, solid and sealed. Sink is in with new taps. Toilet was last to go in but its proving to be a nightmare.
Firstly replaced the innards with a flowmaster flap trap syphon thingy after finding the old syphon had lots of "blue" stuff in it (thanks to the wife), put a new flowmaster inlet in. New overflow (just to be on the safe side), plumbed it all in, checked for leaks and woohoo - everything was watertight.
Then I flushed the loo ............
Thankfully I had a roll of kitchen towel handy as it urinated out the back of the newly fitted doughnut seal.
Now when I took the cistern off, there were two doughnut seals fitted (badly) so I have a feeling when the house was built 16 years ago someone else had a similar problem. They had perished and were rather squished. The pan hole where the doughnut fits in is rather "not round" and the three brand new doughnuts I've got would fit but the gap between the back of the pan to cistern is much larger than the gap between the front of pan to cistern (all 3 toilets in the house, all Shires are the same). Walls are reasonably true and floor is reasonably true.
I tried the previous botch of using 2 doughnuts and while it is almost working, if you do a long flush, you get a squirt of water down the wingnuts.
On top of that, the water inlet to filler now has a very minor weep. I've tried a new fibre washer (and soaking it first) but the problem persists and I don't want to tighten up the nut any more than it is (hand tight then 1/4 turn and a little bit after noticing the weep).
Anyone know if a Shires bog manufactured in 1994 needs a special doughnut ? I'll probably go flexipipe to inlet with a rubber washer as I've had no problems with these in the past although the existing cold feed plumbing is going to be an absolute nightmare to try and get a 300mm pipe onto.
