40mm waste pipe and connecting to access branch All aspects of plumbing questions and answers, help, tips and information

I'm trying to connect a 40mm grommet into an access branch, but the new grommets wont fit in, it must be an older access branch, on measuring the opening a 50mm diameter might do the trick, but cant seem to buy one, any ideas where I could get one.

Hi dialy
You’ll have to try different manufacturers eg Floplast, Osma, Marley to find the right size. Look at the fitting and see if it has a manufacturer on it.

I've tried several different DIY places and bought 40mm grommets ,.they all seem to be around 63mm and.just wont push in, I reckon the soil pipe branch has been discontinued , bit lost now really,
