New shower not draining - HELP!

Hi, not sure if this needs a fresh post but I'll try here first as very similar problem.
I also have a low profile tray which sometimes threatens to overflow. If I leave the top cover in place then turn the shower on, water level rises quite rapidly. If I lift the cover out there is a gurgle of air and then when I replace it the water drains fine. Appears to be some sort of air lock. With shower off and the water drained, the water level in the trap does not fully cover the outlet. This seems to cause can airlock stopping the waterms from draining. Once I lift and replace the cover, the trap fills up and all sorts well. Is this normal or should the resting water level sit above the outlet. I will try and upload some photos but hope this makes sense meantime😊

You need an air admittance valve put in the waste pipe to stop it vacuuming.

Thanks Phil99, . Can't upload any photo as new user but your suggestion makes sense. Will this involve lifting floor or removing the tray or can I fit it somewhere further along the system like where it drains outside?
It's not a huge problem at the moment so long as I lift and replace the cover each time.

I can't answer that question.


It may be better to get a plumber to do it.
