Sink waste pipe come apart and won't go back together

The attached photo shows the waste pipe from our kitchen sink.
Stuff has been shoved in the cupboard and pushed the grey pipe out of the white one and now they won't secure back together no matter how hard I push them together and tighten up the white screw fitting.
Short of paying a plumber a million pounds to fix something which is probably easy, what can I do to fix it, please?

I have no specialist plumbing tools and no plumbing skills.
Thanks.

You may have tried this, but...


Unscrew the white 'nut' & put it over the grey pipe, ready to go back into the white fitting.

There should be a rubber washer somewhere, quite possibly it's fell off, or is inside the white fitting. This also needs to go onto the end of the grey pipe, ready for pushing back into the white fitting.

Position the washer near the end of the grey pipe, then push the grey pipe into the white fitting, so that the washer seals between the 2. But continue to gently push as far as it will go.

Then slide the white nut up the grey pipe & screw onto the white fitting. A pair of gardening type gloves will help grip & save blisters.

That should be it :smashin:

I hope it makes sense.

I can almost guarantee that pushed down inside the white pipe (or on the floor of the cupboard) you will find a black washer/gasket that you just need to put back around the grey pipe. It's happened to me too (many times) :smashin:

ie put the white collar on the grey pipe, put the black gasket/washer around the grey pipe, push the gasket towards the white fitting slowly with the collar and tighten.

Edit: what he said :)

Took the white 90 degree turn bit off and it looks like this in the end the grey pipe plugs into. There looks like a black washer down there, but it's stuck.
The grey pipe fits flush down between the inner and outer pipe. Except it must have shrunk. Or the white pipe expanded, because doing the screw up doesn't hold it in place any more.

Any of the DIY sheds will have them, or probably Wilkinsons if you're near one of those

Actually the white screw-on ring on the end of the white 90 degree turn bit serves no purpose whatsoever as tightening it up doesn't actually do anything. Confused.

It will do when the rubber washer is in there :smashin:

What he said... You need that black washer...


As so... Although this one of mine isn't very black any more...

If all else fails you can always just push the pipe back into the joint and then run a bead of silicon sealant around it. bit of a last resort though

Thanks everyone. The black washer had indeed been forced into the pipe. The wive managed to get it out with a small screwdriver and it connects back together perfectly.
Job done, back to bathing in the sink :thumbsup:

Should waste water from washing machine be fixed with tubing and jubilee clips? I've just pushed the pipe into a larger pipe, with U bracket (supplied with the macine machine) and some shoe lace. It can't pop out, as the worktop is holding the U bracket down onto the length of pipe. but if there is a blockage in the pipe, it'll blow back and leak. The waste is not shared between the sink it's seperate pipe all the way to the outside drain

its how a lot of people do it but you but your right if it backs up then it will flood an alternative is to fit one of these or similar and use a jubilee clip as you suggested

Found a jubliee clip. One thing on the bottom though is not held in properly, it's just pushed in. Can't see that holding up to water pressure if it blocks and blows back.. Found that grey pipe/fitting. Looks similar to stuarts grey pipework.

You can get a proper connection kit for the waste,would be a good idea in your case as it's above the power socket and a leak would not be good.The socket should have been fitted well above and away from any potential leaks.

That's the only place it can go, it had to be moved there because so tight a socket on the side wall would have meant washing machine would whack against it.

Must be lovely being Stuart,

posts on here with a sensible q and within seconds has polite helpful answers (as opposed to being told to ring a plumber). Even to the degree members take their own sinks apart to demonstrate!

God like!

That may be so, but as Andrew has said, definitely get a 'proper' fitting on there, it could save you a lot of hassle, and in extreme circumstances, prevent a serious problem. At least try & fit the pipe properly - loosen the jubilee clip, push on properly & tighten. But you could get a new 'proper' fitting for a few quid form Screwfix or similar.

All these years of running the forums has now been worthwhile for him - it must be the only reason he does it :D

What do you mean by proper fitting? I've got the cone shaped thing plus hose, just worried about the push fit on the white elbow piece.

That should be OK, if you get a blockage it will back up into your washing machine, not blow a connection. The pump won't be that high a pressure. I would try and push that flexible hose a bit further onto the grey fitting though.

of course it's just stuck on just to get it in the picture. That jubilee clip is a bit small, will pickup a a box of clips next week. Not going to use the machine until then.

Ah, I see, no problem then :thumbsup: I would think about trying to replace that electrical socket with a weather proof one though.

could put a clip in to support that upright grey pipe as well more to stop someone accidentally knocking it out of the white bend than anything else
