Hi I am fitting a sink and toilet into an upstairs airing cupboard. Due to building regs, I do not wish to fit a new sewer and stack pipe and therefore am using a saniflo maserator. Question: For asthetics, I would like the sink waste pipe to run along the floor and wall to the maserator and box it in. This will mean the pipe is below the input level for the maserator ie creating a rather large "U bend". Any problems with this idea. Your thoughts would be greatly appreciated. The sink will have a normal U bend at it exit. Basil53
