I have a problem with a downstairs toilet not clearing solid waste. It's an old type Royal Doulton low level type with a bottom exit into the drain. It has a full flushing syphon type cistern.
Suspecting a blockage it has been removed and pressure washed through and is clear. The underfloor drain pipe it connects to is plastic 5" (?) which goes off under the garage door and out towards the road, obviously at a pretty shallow angle.
The flush operates properly and it doesn't back up but it mostly won't clear solid waste of any quantity, nearly always needing a bucket of water thrown down it to shift the offending article! The only thing that has changed in the last 5 years or so is that the neighbours had an ensuite bathroom fitted and the waste pipe from it was brought across in front of the house on our shared drive and joined to the main shared waste pipe by where the manhole/junction is, not sure if it's relevant.
can anyone suggest what the problem may be?
Many Thanks.
