Hi all,

I need to connect my bath drainage to my new soil pipe. I have only one spare entry to boss into the pipe at the very bottom (see photo). As the inital entry out the wall will be on a gradient I was wondering if there was a combination of elbows I can utilise to get a 90 degree vertical drop down to the entry point? As I'm using 50mm pipe I'm not sure I can fashion something on an angle, similar to boiler condensate pipe the other side.

Or would it be easier to just employ a strap boss further up the soil pipe?

Cheers. P

If you are feeling brave, get a solvent short boss from Screwfix. cut out a section, open it up and glue it in place.

I have had bad luck with straps-ons.

Get your mind out of the gutter.

Also, 50mm might be oversized for a bathroom. You could drop it to 40mm

BC are insisting on 50mm due to the distances involved. Whats your issue with a boss strap?
 
Look ugly and have had them leak.
I got a Floplast boss strap from Screwfix yesterday and mocked it up and the thing I noticed was the how close the entry on the boss strap was to the wall which will make drilling the hole a bit more awkward
