Hi,
I have a shower that will be connecting directly to an underground drain, on a vented stack.
Its a slimline tray, so I need a 90mm hi-flow, but do I need a deep seal trap as well or a bottle trap?
The one in the link..

says a 50mm water seal but I can not see how any seal is made in this one?
I guess I am misunderstanding the situation as 50mm of water cannot remain in this trap after the shower has finished? And I assumed the point was to trap water like a U-section of pipe?
