When we had our kitchen installed they must have put the sink and pipes in the work top and then installed the work top.
To avoid the back panel of the unit the pipes have been fitted at an angle. The pipes almost touch the fixing nut. Therefore you can’t get a box spanner or even a flat spanner on the nut.
I can’t take the sink out as there is a screw at an angle that I can’t get to behind the bowl.
The only way forward I can see is to cut the tap off above the work top.
Then cut the rear of the unit out to have vertical pipes to allow the fixing nut to be used.
I have called people out but they have a look and then are never seen again.
Any other options? Do new tapes come with down pipes?
