Hi im installing a wetroom shower tray the trap that comes with it is 50 mm diameter I was going to run in 50 mm waste pipe / Elbows and Tees the under floor in solvent weld , and as it goes outside into the stack in push fit ( for ease of getting into if there is ever a blockage ) trouble is the not much of a selection in 50 mm as there is in 40mm ( i want it in black outside and pushfit ) so if i go down to 40 mm will that massively reduce the flow I know you can get a reducer straight after the trap outlet ? cheers

can you get 1 pint of water into 3/4 pint jug? look at what your shower puts out, see what the tray takes , is it a fast flow waste ,look at the inst.

Try BES mail order based in Birmingham. Terrible website but good catalogue and comprehensive range of black solvent waste fittings. Should be able to use 50mm black solvent into universal push in strap-on boss externally. They even have 50mm black push-fit fi you prefer that!

no i"m not saying " No " to reducing it but look at what each unit will take. the point is if you have low level tray , shower gives 11ltrs waste say 9L you have a flood!!! now said all that , most times you can get away with just banging the thing in, 40mm is normal ok, but i try to check every thing.
hope that helps.
