Replacing P trap under kitchen sink

[EssGee93]

Hi there,

My under kitchen sink p trap is slightly leaking, I've tightened the nut and still a leak there. Looking to buy a replacement and the code on the pipe just now is McAlpine EN 274 3. Anyone know where I would get a replacement and I've seen various sizes? Thanks

Thats it. You can see the leak just there. Not sure if only needs a washer or whole new replacement. Cheers

Take apart make sure everything clean few wraps of ptfe round 0 ring/ washer maybe very thin smear of silicone sealant re tighten.
If that fails new trap have a look on screwfix large selection.

Looks like it’s dropped undo the leaky nut and lift the nut and blue washer up then lift the trap up until it stops around 2-2.5” should be into the trap then slide the nut and blue washer down and tighten shouldn’t leak

That's a good pic, EG 93!
When you look at it, you'll notice that the 'outlet' pipe on the right is slightly above - or nigh-on level - with that leaking joint. That means that the whole 'U' part is always full of water, so if the O-ring there isn't perfect, it will seep.
Best first step is to place a tray under there to catch the waste water, and then undo both of these hand-tight connectors. If you're a complete newbie, then the one on the left undoes anti-clockwise as you look down on it, and the RH one undoes clockwise when ditto.
Undo both of these and you'll have a U-bend in your hand. Examine the O-rings on each end, and see what the issue is. Photos and come back on here if uncertain

Thanks guys, it seems as if as above said it has dropped! I moved it back and and tightened for now and no leak but the blue washer has snapped and needing replaced so I've ordered and new one to do so. Thanks again!
