McAlpine BOSSCONN110 TBL Mechanical Soil Pipe Boss Connector - Black

I moved my soil stack from inside my house to outside. I then had to connect the bathroom and kitchen 40mm waste pipes to the soil stack. With the 57mm hole saw fitted to my drill and on a slow speed, 3 the 5 minutes to fit to the soil stack. Fitted correctly, they have a slight angle for the fall on the 40mm waste pipe. Follow manufacturers instructions, and you can't go wrong. So easy to fit for the normal DIY'er (I'm an electrician by trade) and far better than the Strap-On fitting, and looks so much better. Very happy with these fittings.

Needed to connect a sink waste to a toilet waste. This made it easy. Great device!

High quality fitting with brilliant and innovative self sealing attachment method. This is critical in waste pipe management and boss fitting. Works a treat. I coupled this with a non-return valve which fitted well and provides an excellent solution to a tricky plumbing solution.

Clever design very easy to fit very good buy

Does the job and the only tricky bit was drilling the hole in the cast iron pipe.

Really easy to use if you follow the instructions. as you can see in the picture i have a cast-iron pipe, I bought some long Jubilee clip to put around it it makes it really secure I would recommend this

My very experienced plumber was very dubious about this at first. His experience of cement-on bosses had been far from perfect. However, when he fitted it he was over the moon and is adding some of these to his stock and asked me for a link.

Perfect for the job and priced well
