Browse Forums Bathrooms and Laundry 1 Oct 06, 2017 11:46 am Hi all, Long story short, my fathers newly renovated bathroom (ground level) has had an unknown amount of concrete poured down the main floor drain. Are there any suggestion of how best to go about fixing this problem without ripping up the floor and starting again? He has mechanically chipped away what he can get to, but the pipe then bends 90deg I believe and getting further is proving near impossible. Are there any solvents that will dissolve the concrete but leave the pipe undamaged? Or tools that will mechanically break the concrete around the corner? Any advice much appreciated, thanks.
