falling waste elbow under kitchen sink

[gas-eater]

Hello all. Noticed a pool of water under kitchen sink. Checked the waste pipe and found the grey elbow in corner was totally slack on the pipe (see photos). Took apart waste pipe and seal seems ok. There appears to be a gap of about 5mm when pipe is fitted into this corner elbow. My question is do i need a different size elbow, or different pipe size or an adaptor of some sort. When i push home pipe and elbow, the elbow just slides down again. The sink was fitted in 2012. Im amazed that its held for that long, as there was only a slight weep on it before. Thanks.

Welcome to the forum gas-eater, and just like your name is the kitchen a bit smelly from all that drain gases cos there doesn't appear to be a trap installed to stop them entering your property?

Throw away that dark grey pipe which is to small & fit something like this http://www.mcalpineplumbing.com/traps/sink/sink-plumbing-kits/1-189-double-bowl-sink-kit.html
You will then need a piece of 38mm push fit waste pipe to extend the bends up & connect to the trap outlet which will fit.

Thanks Chris. Yes did join a while ago but I follow posts on here regularly , as it's a brilliant forum to get valuable information. I think i will fit the the mcalpine sink kit you suggested. Does this kit come in grey colour?If not, i will still fit it as suggested. Just seems strange that the pipe already installed is small. I thought the sink waste kit came with the sink when I bought it. It was fitted by kitchen fitters, so maybe that explains it lol.
Thanks once again.

It does comes with the sink, it is one of those B&Q or Ikea specials i.e. imported crap.
Anyone worth their salt would throw it away & start again.

I would have a good look behind the sink back anyone who doesn't install a trap might have left any number of surprise's.

Traps are always white & you can pick up the 38mm pushfit waste pipe & fittings from B&Q as most plumbers merchants will not stock it (classed as diy) white or grey push fit will all fit each other, but make sure you clean off all the burr's after you have cut the pipes.

Yes, I will check back of sink, just to make sure jobs a good un. No foul smells in kitchen , but definitely gonna fit new trap and 38mm waste.
Thanks again
