I have my bath and shower on the same waste run. When the bath is emptied from full, due to the head of water above the shower tray level, some bath water bubbles up into the shower tray.
I was going to fit an inline oneway valve to the shower waste run before it meets the bath waste. A plumber told me I just need to fit an anti siphon waste to the bath and this will solve the problem. Firstly how do these things work? Secondly is he correct, will this prevent the bath water running up the pipe and out into the shower tray?
Thanks.
