Hi I wonder if anyone can help? I have recently had an extension and had a new bathroom fitted upstairs as part of it.. the "less than helpful" plumber fitted a dirgo valve on top of the pipe which I then boxed in.. The toilet has since been fitted and although working fine initially after a couple of days the loo started filling up with water and takes an age to disperse.. as if blocked, I have unsuccesfully tried sulphuric acid to remove any possible blockages although this is highly unlikely as the toilet had only been in for a few days when this started occuring. There is very little suction and a friend suggested that the Dirgo valve may be faulty or need adjusting, I wanted to see if anyone thought this might be a reason as it will involve me removing tiles which is a pain.. When I boxed in I didnt leave much of a gap between the top of the valve and the ply.. could this cause any issues do you think?
I would appreciate any advise anyone could give.
