shower waste connection

djh

So for better or for worse, this is the situation ...

There's a 110 mm soil pipe sticking up out of the concrete slab. There's a shower waste with a horizontal outlet. There's very little height under the shower tray. What's the most effective (i.e. needs least height) way of connecting the 1 1/2" waste to the 110 mm drain?

My best thought so far is something like http://www.pipescenes.co.uk/upvc-waste-to-soil-adapter-cap-pipe-reducer-110mm-4-to-40mm-1-1-2.html

Yes plus a street elbow to go into it, not a bend.

A strap on boss might be lower? Especially if you can chip away some of the conc without damaging the pipe.

unless you chase the concrete then no, and if chasing concrete then what you are doing could be just as low.

Dunno. I get a warning from the site that "JavaScript seems to be disabled in your browser", which is correct. I expect to be able to browse with no Javascript. But maybe that means I'm not seeing an attack that your system does.

My plumber talks about an MF elbow rather than a street elbow, but I think he and Tony are talking about the same thing. The plug sits flush with the surface (or as low as you chip away) and then you have the radius of the bend, insofar as you can't press it into the plug. With a boss, I'd have to allow for the plastic collar around the boss instead of the radius of the bend.

Anyway, it's a good reminder not to cut the 110 pipe off too short yet, whilst I play around with the options to see what works best. Some more SDS chiseling to do first. I wish the job was big enough to justify hiring a jack hammer, they're so much faster than the 5 kg thing I've got.

Thanks again, chaps.
