Apologies for group cross posts but:
I have a 1970s property which AIUI is probably one of the last in the UK to
be fitted with a glazed drain piping system.
I am looking to replace the original downstairs WC with a more up to date
The waste drain outlet is cast into the concrete floor approx 270mm from the
wall of the room.
The problem I have is that the existing toilet has a down pointing waste
outlet which is mortared into the flared socket end on the drain pipe.
So above floor level I have a 200mm o/dia socket which tapers down just
before it enters the floor.
Without breaking up the toilet (which I understand is the accepted way to
remove it) and cutting/chiselling out the mortared in outlet, I am not sure
below concrete level.
The questions are:
Is the drain pipe below the socket a standard glazed swept bend type
If so, does anyone have a link to dimensions for these?
Can I simply cut off the socket and taper to leave the pipe flush with the
concrete floor? If so how is this best achieved?
Will this leave enough straight pipe below floor level to provide engagement
for a plastic waste fitting pushed into it?
Is there a fitting to do this job i. e. go from a horizontal toilet outlet
into the bore of the drain pipe that will be left after removal of the
Any other pointers on this appreciated.
