Hi, I'm not a plumber but I've watched various plumbers pull my Armitage 17420 (purchased and installed 1998) apart, scratch their heads and put it back together enough times now to know how to do this operation and have done it a few times now myself.
The problem is the toilet not flushing as Tom describes on a youtube video for this type of toilet. The British Gas plumbing engineers swapped out all the internals, siphon, inlet valve etc but nothing doing. The pan fills with water and drains slowly leaving most the contents in the pan. If anything it was worse than before (with the siphon with broken diaphragm)
Eventually one of the British gas plumbing engineers realised this was a siphonic toilet and suggested I get a new airex bomb as the rubber seal had perished on the old one, which they would then fit. They did this but it didn't help.
I noticed that when I pulled the cistern off the pan that the rubber seal on the bomb was pushed right up to the top of the bomb where the strengthening fins of the bomb interfered with the seal and the botton of the bomb tube pushed against the base of pan area where the bomb goes into. So I figured it was just not being fitted and located well. I tried to refit carefully. I got minimally better results but still same problem.
So the next thing was that the bomb was sitting too low when pushed into the bottom of the siphon. I cut down the old bomb to just above the top of the inner tube on the bomb and used the new seal. the Seal now was better positioned and did't slide up to the top when the cistern refitted (had to fit and remove to check).
Same results.
So I was wondering if the cistern needed a particular type of siphon what places the bomb in the right place when the cistern is fitted. But I notice from another post that so long as the bomb fits the diameter of siphon outlet (which it does snugly) that this doesn't matter.
So are there any thoughts? Would I be better to cut my losses and just buy a cheap toilet temporarily to replace until I get the bathroom refitted, or can I fix this one economically? it used to work just fine. Cheers
