Rated 5 out of 5 by from Awesome adapter Once cast iron pipe was drilled you just pop it in tighten it up and jobs a good'n. Would definitely use again!! Has saved removing a cast iron soil stack which let's be honest is not much fun. Can't recommend highly enough.

Rated 4 out of 5 by from Good not Great 57mm hole saw through the pipe and tightened up the boss, I was putting a u bend, dishwasher Waste and sink waste directly into the boss and it seemed a bit flimsy, took it out applied silicon to all the mating faces and around the rubber seal put it back in and tightened again, wrapped a large cable tie around the top and bottom and tightened - boss doesn't move now and no leaks at all.

Rated 3 out of 5 by from Pipe Boss Review The Pipe Boss is well manufactured, but the installation instructions are appalling:- the picture of the fitting tool was so badly drawn that I thought it was missing from the pack (and I'm an engineer and familiar with looking at technical drawings). The last person to purchase it also couldn't figure out how to install it, so had returned it to store after opening the bag. The tool is plastic and has lugs ('ears') on it. Once you understand this, installation is easy. There is no online video regarding installation. The fitting itself is smart, neat and well engineered.

Rated 5 out of 5 by from Pipe boss (mechanical) This is a very good product,however the instructions could be clearer,the fixing tool should be removed from the assembly in the first instance,I thought it was part of the workings and failed to recognise the part for what it was,also the the drawings 2+3 on the instructions have omitted the lugs on the tool,had they been drawn on the part would have been easier to identify,excellent product when I realised how it worked.

Can this item be used to make 110mm tolit outlet to a 50mm or 40mm

Asked by: Bellayella

Will 60mm hole be fine

I've got hole cutters at 54mm (too small) and 60mm (too big). I've made a 60mm hole in a test piece of pipe and the bos adaptor does fit, and appears to be well attached, but will this be fine for the real hole? Thanks, Simon

Can this be used on underground orange pipe?

Asked by: blueforest
This boss does not require any sealant or glue (I suppose you could put some in if you really felt it needed it) so it should be fine on the orange underground pipe.

can the 40mm connector be angled? my bath waste pipe needs to be at a steep angle because there is an S curve where i need it to connect. therefore i need to place it further down the soil pipe

Asked by: xarcane
Having only just bought one of these for the first time I believe the way it is designed the large curved section of the fitting should be held tight against the soil pipe to make sure it creates a good seal. The angle is set to 5 degrees and there seems to be no leeway so I'd say no, you're pretty fixed at the angle the fitting is set.
