Hi, i am about to install a stoneresin shower tray onto a concrete floor, do i need to raise the tray for the waste to fit under - if so whats the best way to do this?
If not when the waste pipe goes outside under the floor, can this go straight into a manhole? drain? and does it need a none return valve?
thanx
