Shower waste advice

[Nmidia]

Hi, we are installing a shallow shower tray with a high flow waste on it. This will run to a shared soil stack in the bathroom about 1m away. The tray and pipework will be raised above floor level. My question is, does the high flow waste provide a seal as per a u bend or do I need to install a bend of some sort? Is there anything else that should be fitted when connecting to a shared soil waste? I estimate that I will raise it by approx 10cm/4 inches and sit it on ply and blocks.

I need to check but I think it is 40mm pipe work at the moment. Is this sufficient for draining the shallow tray or should I aim for 50mm?

Thanks in advance

High flow waste incorporates a trap so nothing else required. 40mm is ok, especially as it is quite short.

Brilliant, thanks for the advice

Check that the waste will indeed take a 40mm pipe. Some come with an adapter (there's another thread about this) which means that the waste has to reduce - defeating the object in my opinion.
