I have a new whirlpool bath from b&q with a waste pipe supposedly measuring 1.5 inches as standard, however none of the 1.5 traps I have bought will fit this. I need a bath and b&q won't help. Any ideas?

Hi Scatty

Are we talking 1.5" TUBULAR tub waste assembly size VS 1.5" drain pipe size? If so, there is a transition fitting called a "trap adapter" (or desanco adapter) that mates these two different materials... ;)

Let us know the pipe type and size of the drain pipe (PVC, ABS, copper, etc. ) and the material of the "tub waste assembly" piping, OK?

I believe you will need to make a trap or buy a PVC trap that is 1 1/2", not a poly sink trap. Schedule 40 PVC is bigger than the Poly piping used for sink traps. Flex PVC drains from a spa are usually the same size as schedule 40. That's how I had to do mine. Use PVC glue to mate the flex to the solid.
