Nylon washer for 50mm pipe

[newts]

Pushfit waste pipe is ~2mm smaller than solvent weld & harder to tighten down, a replacement washer pack (rubber & backing washer) is all that's required. You can't solvent weld pushfit pipe as it's polypropylene not upvc.

True, if I can’t find the washer I could take the little elbow off and find another whole one.

You don't need to take the elbow off. Unscrew the compression nut at the rear of the trap (there'll be enough room to slide the stub of pipe to separate the joint), slide on new washers, reinsert pipe & re-tighten the compression nut on the trap.

Aha - the push-fit joint means the piece of pipe to the compression joint is also push-fit pipe. Push- fit pipe (although nominally 40mm diameter) is a bit small than solvent-weld pipe (maybe 2mm on diameter?) This can make it difficult especially when parts aren't new because the rubber hardens as it becomes old, the rubber deteriorates and also may be squashed out of shape and fit when new, but won't when old. I notice the compression is a Nuflo (is that a screwfix 'own brand'?) You could just get a (cheaper) straight connection of the same make and use the seal and ring out of that.

That trap is a Nuflo shallow bath

try Jewsons for a seal replacement or go the whole hog and turn the trp clockwise to remove the right angle joint and go straight into the long run (depends on how it connects to the right of the photo)

Here is the bend part

That Nuflo trap is a shallow seal & should not be used if the waste pipe is connected directly to the soil stack. The existing waste pipe is to the rear of the bath, that's why a swivel trap was used originally for easy connection. The threaded elbow that the OP has removed is an integral part of the deep seal trap & should not cause any issue whatsoever if correctly installed. The main issue that's caused this leak is the unsupported waste pipe is sagging/under stress in the area of the push fit elbow adjacent to the trap (you can see that the short stub of pipe is angled sharply downwards where it enters the compression joint on the trap).

This should work?
I had to unblock it all it wasn’t leaking before.

You don't need to replace the part in your link above, just refit it all with a new washer set I linked in the first page🙄

You could also just use this new trap and connect straight into long pipe yes?

Then you’re manually setting them up hoping they’ll seal. The part has them fitted so it’s plug & play

But the old one has the non return feature to stop smells.

The mcalpine elbow probably won't fit the nuflo trap as the threaded part is not a BS thread on the mid joint of the existing trap.
You could have just replaced the seals as suggested & all would have been done in 10 minutes. Alternatively just buy a complete replacement swivel bath trap like you already have. You appear to be making a mountain out of a very straightforward & simple repair?

4 weeks ago I found that linked seal kit in my airing cupboard. Now it’s gone as I need it. This causes great frustration. I will pick up another but it better not leak. Settled on this, thanks newts.

I like Mac alpine. They have an internal collar which slips inside the next piece of pipe. So as long as there is a slight fall there is very little chance of leaking. You must support the pipes so they don't sag and pull the joints
