32mm standpipe trap ?

[mike42]

Hello All

I want a standpipe with trap at the bottom for the condensate to enter. So I (stupidly?) bought a mcalpine 32mm P trap before realising I didn't know if there exist adapters to connect 32mm pipe onto the waste side of the trap.

So far I've bought this which of course doesn't fit.

Is there anyway to connect 32mm pipe directly to the inlet of the trap? If not, do there exist 32mm washing machine style traps?

Thanks for reading.

Thanks but clearly that won't screw into the waste end of any trap.

If you want a standpipe and trap ,why not just buy one ?
Don't really understand why you have bought a 32mm P trap ,which would usually connect to a basin waste ?

haha - I'm beginning to think I don't either

I wanted and still want a length of 32mm pipe going into a trap at the bottom and then out the wall in 32mm. If I have to make that a 40mm washing machine pipe and trap then reduce down I could but not ideal

The 1.25" BSP adapter you bought should connect to the top of the 32mm trap as that should have a 1.25" BSP waste connection, does it not fit it??

No! The threads fit but it won't fit and push down over the spigot. Compared to the join in the middle of the trap, the plastic is thicker so the internal diameter is slightly too small to pusher over and meet the o ring.

At this point I'm resigned to throwing away this trap. Is the solution really to have a 40mm standpipe reducing to 32mm? Seems to go against all the principles of waste where the pipes get bigger and bigger as you move down.

Ah ok - yeah, sometime get that with McAlpine traps and certain basin wastes - trick to that is get a nice sharp stanely, take the seal off the trap and whittle the flange down a bit, that and/or a bit of 80grit and sand out the ID of the adapter, doesn't need much to get it to fit.
