Upstair shower leaks into the kitchen below.
tried tracing the leak, checked all the usual things, but essentially, if I take the shower fitting off the wall and connect a pipe to the brass fitting and run water under mains pressure from the mixer tap into the shower cubicle, it doesnt leak
if I put the shower fitting back on the wall and turn the tap on with water coming out the shower head, it leaks underneath the shower tray.
the tray water outlet is dry and doesnt leak, I have used a seesnake camera to check the mixer valve, that doesnt leak.
any ideas why it should leak with the shower fitted, and not leak without the shower fitted,
baffled or what
