i have just installed a new bathtub and new waste pipe which is 40mm PVC, It goes into a 150mm dia clay pipe in the ground.
What is the best way to seal up the connection? i plan on mortaring in up, but are there any tips to doing it, as i am worreid the mortar will drop into the clay pipe and clog it up while it is still wet.
The 40mm pvc is not centred in the clay pipe.
thank you in advance
