Basin waste thread needs lowering?

[markwm]

The height between the thread on my basin waste and the waste pipe outlet in the wall is approx 220mm, which seems a bit too high for most of the chrome height adjustable waste traps on the market.

So what components do I need that will give me a 32mm thread a couple inches lower than my current 32mm basin waste thread is at now?

can't you raise the waste pipe ?

No as it's in the wall and on 'show' so it needs a chrome bottle traps that goes straight into the wall.

I made a slight error when designing the bathroom in that I didn't measure exactly what height tolerance I had to play with between the basin waste out the waste outlet. I'm a couple inches too much.

is this a plasterboard stud wall ?

move the waste pipe,or use two elbows

Yes...

The outlet pipe must go straight into the wall and have a cover plate. Having elbows there will look crap.

My thinking at the moment is to buy an el cheapo white telescopic trap. Remove the telescopic bit and attach to waste. Then put a 32mm compression coupler on it at the desired height. That should give me a lower 32mm thread that will accept the nut of a chrome bottle trap, correct?

how are you joining the chrome waste to the waste in the wall ?

and doing that won't

cut a peice out of the wall and raise the waste

easy enough to make good after

32mm push fit, most of the chrome traps are usually. I have 32mm push fit in the wall.

Not a chance I can do that. Tiled and everything!

are you hoping to push the chrome waste through the hole in the wall into the pushfit ?

It depends on the bottle trap. Some are more like 40mm and slot over a 32mm pipe. Others will push straight into the 32mm elbow I have in the wall secured to a timber backplate. I've tested it before concealing and it works.

Connection into the wall isn't a problem, it's finding a trap with a height adjustment of upto 220mm or so.

long as you've tried it in the pushfit as some won't fit a pushfit.

this is a long shot but some it can be done.

will the long waste on yours go in place of the short telescopic part
and screw to the basin waste.

 

[markwm]

No because the telescopic parts always have flanged ends. The outlet pipes are just straight pipes.

as i said many can't be done cause of the basin connector flange.
only ever seen one thats interchangable.

can you not remove a couple of tiles then cut the plasterboard and alter the waste refit plasterboard and tiles.

thats the way i opt for may take longer but least once done its done properly
