Hi, we’ve recently had the old waste pipe (grey) in our house replaced (black) and we’ve noticed that when the toilet is flushed, a pool of water comes from underneath the contrite and pools. There is a crack in the back of the old grey waste pipe but I’m not sure if that’s the cause? Does anyone know the extent of how to fix this or what it would be? I have a video but I can’t upload it so have taken screenshots from it and added them below.
Thanks
Thanks
