Cheers much appreciated but while we are talking Dalmer traps which way does the rubber go up? Both sides has a lip although one lip is taller than the other and also one side is like an old record with lines going around inside the lip but the other side has no lines? So Which butts up to the tray and which side sits on top of the the plastic trap?
thanks

finally got back on the wet room and I had left the Dalmer shower waste that I had routed outside full of water to check for leaks as I had sealed the outside end. The thing is there are no leaks but the trap is only holding water half way up the trap and therefore there is an air gap in the top of the waste pipe? I have checked the tray and trap are level which they are but once I let water flow out the end of the waste pipe (into the garden) the water level in the trap seems to drop too low? Surely this will allow waste gases from the soil pipe back through? Any thoughts?.

No it won't so long as you use the internals of the trap as it prevents any air through. The rubber seal at the top if the internals create a tight seal also.

Thanks Plan Tec that puts my mind at rest. I had put all the bits and pieces back in the box so didn't occur to me as the trap was just on test so to speak. Much appreciated pal.
