Broken waste pipe

[vegasgo]

Hi everyone the 40mm pipe to our free-standing bath has snapped right off where it enters the wall (someone sat on the bath and it tipped forward...). Just wondering the best way to fix this, I guess looking for some kind of reducer or gasket, then hoping the pipe isn't cracked further along inside the wall. TIA.

You could probably bodge it with a bit of 32mm glued into the pipe, if it's solvent weld, but then you won't have the correct size bath waste, which should be minimum 40mm all the way.

How does it exit the wall? I'm thinking - see it might push out through the wall, without doing much damage to the surfaces, then just put a complete new section in.

The pipe goes straight to the soil stack, the obvious thing to do would be to renew it all but access isn't good on the outside. The 32mm pipe option is probably best even though it should be 40mm - if only a small section is 32mm is that really an issue?

Not ideal, but if you really are stuck with no other practical solutions, it might be an option.

The key is if it is solvent Weld (ABS/PVC). If it is then I have got away with a piece of 40mm cut lengthways before. That then has a sliver cut out of it lengthways so it will shrink enough to use as an internal liner, glue down the cut and then glue a new piece of 40mm over the top. All cuts need to be super clean and straight so it all glues up tightly again.

32mm may be slightly too small and the solvent weld cement won't usually fill that gap, you'd need to use an epoxy or similar filler type adhesive IMO.

When you do get the waste pipe repaired, you'll also need to find a way of supporting the bath more effectively. It should not have moved sufficiently to break the waste pipe when somebody just sat on it!

The bath was seemingly stuck down with silicone .... it's been loose-ish for years but as long as you didn't sit on the edge of it then all was fine, until an unsuspecting friend of my daughter's came along. Didn't help that the pipework was rigid, will use a flexi-pipe when I repair it.

No, don't use flexi-pipe, fix the bath! Flexi-pipe, in the drain, will simply clog up with debris.

All the bath needs, is a bit of timber frame-work, to properly support it.

The pipe snapped where it meets the wall and also on the right-hand bend where it leaves the bath - I will only use flexi-pipe here as there is so little room to work with it would be difficult to all be solid pipe. Most likely use flexi for the bend to 40mm pipe, reduce to 32mm and stick it as far as it goes into the wall pipe, pull-back a couple of inches then exposy seal. Will stick the bath to the floor as well.

Can you not just chip away at the grout and get a coupling on, or make the hole a little bigger and fill afterwards?

That Sir is a very good idea, will see in the morning.

That length of pipe, should easily allow it to be sprung into place, I would suggest - no need for flexi at all.

Hire, buy or borrow a diamond for drill, 50mm diameter. Or look up one specifically for tiles.

Carefully core around the pipe in the tile, solvent weld a coupling in place, and repipe the run, and fix the bath down properly, even OB1 or Stixall should be better than nothing. Forget the Flexi pipe

Is it a free standing bath that has a skirt all the way to the floor?
