Got a leak from between the bottom of the sink and the top of the first part of the waste unit. Probably fitted about 11 years ago so maybe something has degraded. The waste unit is pulled towards the sink by a screw that goes through the top of the plug hole in the sink but no matter how hard I tighten it the leak is still there.

Tried to bodge it with some sealant but the leak just finds somewhere else to drip from. I really don't want to have to unplumb the whole assembly an replace it as the dishwasher and washing machine also go through that waste unit, but could there be a sealing ring that has decayed that I could replace?

I checked the instructions online but they were written by Marcel Marceau so no words about what the fitment consists of or how the seals work.



Any tips?

Instructions suggest a seal between the metal strainer and the sink but nothing below. Sure you’re not over-tightening it?

I don't think so, the leak came gradually without me touching it, and while tightening has reduced the leak it's still there, and loosening it makes it far worse.

A new unit is only fifteen quid so I might just buy that and switch out the ring and see if that does the job, it's probably just decayed over the years, everything else still seems in good condition.

Put a bit of plumbers mait around the plug hole and put it back together again.

Bin it and buy something decent like a
McAlpine fitting.

You didn't do a very good job, I've been trying to fix a leak all today. :-/

Unscrew it, take the trap and the seal out, clean everything properly and try refitting it.

If that doesn’t work replace the seal.

The underside of the sink between the plastic body and the sink should have a compressible rubber seal , the one on the top side isn’t required anyway

I fitted one of these traps a few months ago in my previous house and they’re a pain to get water tight, you’ve really got to get the bit/cup (that goes under the sink) aligned perfectly and tighten the crap out of it with the yellow key they provide, it was this that was failing for me, took quite a few attempts to get it right, no silicone was needed, just keep fine tuning and testing as you go.
