I usually try and run the waste under the plyth. If this isn't possible is it ok to run higher up behind the unit. I think there is usually a 75mm void? Would then require the joiner to knotch the back of the units.
What is the unit called that the ground source heating pipes go to to transfer the heat from the refrigerant to the heating pipes to go around the system? Thanks
If fitting a vanity basin like this. Would it need the basin bolted to wall or just siliconed to the top of vanity and wall. The unit will be screwed to the wall
If fitting a vanity and concealed cistern in a cloak room. Is it best to Lino/laminate under the units. I.e fit first or fit the units and the the flooring after? Thanks
