Kitchen Waste Pipe - Please Help

[samtaylor15]

Hey Everyone,

I'm redoing my kitchen at the moment and have a question about the waste pipe.

In the corner of the room is the main waste pipe coming down from the bathroom. The connecting fitting looks like it has been bonded, so I doubt I can get it off (not tried), my only other solution is to make use of the current fitting.

At the moment the adjoining pipe just sits inside the fitting and easily comes out, it has no rubber seal to compress the pipe and hold it in. It looks like a 40mm pipe.

Where can I get a new seal or fitting?
Should I try to take the existing fitting off?

Thanks!

Because it has a thread you might be able to use the washers from a standard 40mm compression fitting.??

Hi thanks for replying!

I tried that this morning, but the washer from a standard 40mm coupler doesn't seem to fit, it looks like there is no room for the washer to sit (see pic). I cant combine the new coupler with the old fitting either, its not tight enough to screw on (see pic).

How about a reducer and a 32mm compression fitting, have you tried that? Although it's not a great idea to reduce the waste down to 32mm.

it seems there is quite a bit of space in there so you could try removing the old fitting and replacing with a new 40mm strap on boss and if all goes wrong, plan B, to replace a section of soil pipe or add a new soil branch.

May have to cut that section out, use a slip coupling and a normal coupling to graft in a new section of pipe. Check the height, you might be able to slot in a boss pipe to replace that section.

I was really hoping you weren't going to say that.

Do you think it would be possible to take off the fitting?

If I do cut it out, is there an easy way to do it without the top section of the pipe falling down?

Thank you!!

Or could I perhaps add another hole lower down and seal up the old one?

 

[longdogs]

Yes, no reason why you can't do that.

That boss has been stuck on with silicone???

I would imagine it would come off fairly easy.

Then put a proper strap on..on and glue with solvent weld glue.

Thanks for your help everyone!!

I think I'll see if I can cap the top one and add one below first.
