Rated 5 out of 5 by from Perfick! Needed to fit a condense pipe into the waste system and using a T this did the job perfectly.

Rated 5 out of 5 by from It does fit..not as expected I was going to take this back because it didn't fit my 40mm pipe (as mentioned in another review). Only thing is you need a straight coupling for the 40mm pipe for this to fit into. I use solvent weld, so not sure about pushfit but I believe it works for both.

Rated 5 out of 5 by from Great solution. Looking at ways to connect the condensate pipe from a combi boiler to a waste water system? This works a treat using 21.5mm floplast pipe, a 40mm connector cut into your existing waste system and floplast pipe weld. And all from Screwfix, so one stop shopping.

Rated 5 out of 5 by from Drainaway This waste reducer is the ideal, cheap and practical solution to plumbing in the pipe from a condensing boiler. Just cut into the existing 40mm waste pipe, fitted an additional Tee connector to take the 21.6mm. Cost of materials under £4, I already had the weld adhesive. Great for diy or professional use. I haven't had time to establish the reliability, but have never experienced any problem with plastic welded parts before.

Rated 5 out of 5 by from Reducer These reducers are stepped to fit both solvent weld and push fit. Very useful for connecting condensate to stack.
