Basin waste thread length

scratching · 30 Nov 2009

I would like to start by thanking you all for the great help and advise posted on this site, its proved priceless.
I'm now stuck with the basin trap to waste fitting. The problem i've encounted is the lack of thread on the waste is preventing the trap from tightening up fully. Is there a particular trap i need to buy for this type off short threaded waste or am i missing something ?

why is the thread so short ? not a useal problem.

Thanks seco services, i've just found the same question asked back in jan 08 to which you supplied the answer to. It looks like i need a chrome bottle trap from screwfix with a shallow nut.
I couldn't find the answer before, so sorry for the repeat post.

i thought that was going to be the issue.
you have a pop up waste with only about 5mm thread below.

Thats the one. Looking at the picture of the trap in the screwfix link posted by you last time, this should sort the problem. Cheers

changing the trap to chrome can create another issue.

the chrome waste is a different size to our plastic waste.
and useally needs a compression waste coupler to join the two together
and can be ugly if on veiw if not being used on a stud wall where you don't see the waste.

This plumbing game aint as easy as i first thought. I'll get the trap and see what i can work out. Dont go far though, there may be more problems to follow.

the other easy way out is look around for another pop up waste and some have abit more thread and you can get away with using a plastic trap.

i change them alot as its pointless a chrome trap in a vanity unit etc.

some will say cut abit of the plastic nut, but thats not really the way to go.

threads deeper on the first one.
