Hi All,
Need some advice with regards to what has been installed in our new build. The main foul run enters the house through the floor in the downstairs WC. A branch connector comes off this to run to the WC in this bathroom with the run continuing up through the house as normal to a slate vent.
The problem is the height of the connection in the downstairs bathroom to the WC. The floor has been screeded and will be tiled on top. At the minute the branch connector is, in my opinion, too high off the floor. The distance from the floor to the midpoint of the soil run to the WC where it leaves the branch is 7.5". I have a temporary WC fitted in this bathroom and with it sitting on a piece of 18mm flooring the soil run to the branch is level! Our tiles with adhesive are likely to be around 15mm max I would have thought meaning the soil run will be flowing back to the toilet!! The plumber who installed it is insisting 7.5" is the standard height to set a run like this off the floor. Can anyone point me to any guidance on this?
Lowering the branch is a real problem as the collar through the screed floor is above the floor level and the branch connector won't go any further down.
Any suggestions apart from digging up the floor and lowering the collar?
Thanks in advance.
