Hello
I'm currently installing a new shower and basin. The drain pipe to the stack will be 2" (55mm) pipe which currently has a fall of 35mm over a 2.8 metre run with one swept bend an two 45 degree bends. Should I raise up the shower even further to increase the fall on the drain (is the minimum fall 18mm per metre?). Also is there a maximum height the shower can be from the floor before a step is required? To get the correct fall the shower tray will be approx. 180-200mm from the finished floor level.
Also is it okay to run the basin waste into the shower waste as long as I use an anti-syphon inline basin trap?
Thanks
