hi, hope this is the right section to post in, i currently have a 82mm soil pipe that takes the bath water and basin water away, i am lookin to change it to 110 mm soil pipe, i have dug the bottom out and noticed it goes in to the drains but is all concreated up or sumhing hard, would it be possible to just get a 110mm to 82mm reducer for the bottom as the ones i have looked at have been more for changin it the other way, hope you's can understand what i mean thanks.
