Leaking under sink

JustAnotherSaver

We had a new sink fitted probably about 2 years ago now, thereabouts. All was well until i noticed tonight that it was leaking.



It's a bit late to start messing about but it's from the bit i've boxed off. It doesn't seem to be a threaded connection & i've tried turning it just now and it hasn't sorted it. There's a sort of insert in there. I'd have expected the one pipe to fit well in to the other but it actually doesn't seem to go that far in.

No idea why it's suddenly decided to start acting up but do these sort of connectors go faulty & need replacing or something? Like i say i've tried tightening it but it didn't seem to work.

I'll have another bash when i've time but i thought i'd just make the post before bed in case someone can point me in the right direction - again like i said, i've tried tightening & it didn't seem to work. Well more than it didn't seem to it just didn't work.

You can see quite clearly that the pipework going into the fitting on the base of the sink is not all in line - its kinked and the bit you're trying to tighten won't seal properly. I had something similar, discovered a few months after having our kitchen redone. In my case a pipe was too long, in your case a pipe may be too short.

I would unscrew that fitting you mention, then unscrew the one to the left of the picture and the one right at the back - where the curved bit goes away from you. This will allow you to pull/rotate the whole shebang, pulling it away from the pipework on the left slightly and allowing the pipework going vertical to be all in line. Then tighten the bit nearest the sink first, then the others afterwards. Basically you're loosening all the important joints, then re tightening them from the sink out. Hopefully there is enough pipe length on the left to allow this. If getting the fittings all to line up vertically means you actually pull the fitting clear off the pipe on the left, then you'll need to increase the length of that pipe.

I'm wondering if maybe that's why the fitters left it like that - the pipe on the left is too short and they couldn't be bothered inserting a piece to extend it.

In short - loosen it - push it up (it come out of the rubber sealing washer) and tighten it.

And curse the crappy waste kit and installer

Well i had a do at it tonight. Disconnected from the main sink end and also the mini sink end and was able to reposition it.

So far so good. I can only assume if i'm pressing on something with a bit of force in the sink when washing (scrubbing something stubborn for example) then the force on the bottom of the sink is pushing the connectors a bit? Who knows.

Once i'd disconnected the connectors i did wonder why they'd cut the piping so short.

The pipework your adjusting.

The website seems to be broken today - when I try using 'Quote' I get two blank blue panels. Anyhoo, good to know you were able to slacken things off and re position the pipes. If the pipework immediately under the sink is all in line, rather than kinked as before, you shouldn't have any more problems. Any slight movement of the sink during use will not have any effect now.

The installers probably just made a mistake in cutting that pipe on the left too short, then couldn't drag it in from the outside waste to compensate.

I would suspect you may have displaced the pipe work when you were placing or removing items from under the sink?
