Title: Stupid waste question I can't find an answer to
Post by bevo on Nov 6^th, 2007, 8:37pm

I am going to install my shower tray.
Does a low profile waste also act as a trap to stop bad smells coming back from the drains?
Looking at the shape of a low profile waste I can't understand how a barrier is made to stop bad smells as with a P-shaped waste pipe.
Sorry if this is a stupid question but some of the low profile wastes state they are a waste and some say trap. Are they all the same thing and do they act as a waste and a trap.
Thanks, Bevo

Provided you have nothing upstream that ill pull the water out it should be fine.

You could fit an HepVo dry waste inline in the waste pipe as an added precaution

Hello, thanks for the advice. I might consider the hep waste valve.

The low profile wastes like these have "cylinders within cylinders" to form the water seal...

Yes it's not obvious unless you take one apart.

The nice thing about some of these is they can be fitted as well as serviced from above - meaning no need for a plinth. Our tray is flat on the floor and achieves much the same feel as a wet room would with less complication.

These 40 mm high trays would also be good with no plinth...

Hello, I will get a waste that I can service from above. The tray is raised as the waste is above the floor level. I bought a just trays merlin tray as I needed an 800 x 900 size and they seem to have a good reputation. It should be here on Monday!!!
Thanks for all the advice.
