Hi I had my bathroom redone recently and ever since when using basin tap I can hear horrible gruggling sound coming from the shower waste. Here is the video: Could you advice please? Is this normal or drain pipes installation fault?
Sounds like the two pipes join somewhere and for whatever reason the water is struggling to flow away nicely hence the air bubbles in the shower tray as it is lower than the basin.
great stuff But why was it not installed to the best uk practice in the first instance. bring on brexit
