I measured the waste pipe under my downstairs closet sink as I want to change the trap to one with a built in washing machine inlet. There is not enough room between the water line and the top of the trap to add a washing machine inlet with clamp.
The pipe is either 34 or 35 mm. I have never heard of waste pipe this size, but went to my local Wickes and then Focus and they don't stock pipe this size. They only sell 32mm and 40mm.
The other end of the waste pipe goes into the soil pipe at the rear of the toilet. It looks to be a tight fit so how would I get a 32mm or
40mm pipe into that hole.What can I do now?
Any advice gratefully received
Steve..
