I need to cut into the plastic risers on an inspection chamber and was wondering if/how to seal the pipes (110mm). I'm doing it for a back drop pipe, and it's only for rainwater. Do I just use sealant around the pipe or is there something better?
300mm drain riser?
Not sure what you are connecting to...
You can get 32 and 40mm boss straps for 110mm soil pipe.
You can get 32mm and 40mm rubber bung to take 32mm or 40mm pipe...
You can also buy service plugs they use after drilling hole for camera..
I think drill 32mm hole for rubber and 32mm pipe.
Look up boss strap and fittings.
Maybe something there you can use
