Hi all.
My shower tray waste started to back up a few weeks ago. It reached the point where I had to turn the water off mid shower and wait a couple of minutes for it to drop.
There was no apparent blockage close to the tray and running a 8mm dia drain snake through it went all the way through to the stack with no resistance.
I bought a £10 endoscope camera off Amazon and attached it to the front of the snake. Running it through the pipes to the stack the pipes barely had a stain on them. I was amazed the camera worked so well actually.
The shower tray outlet is less than 2m from the stack. It's 40mm pipe all the way through. The fall from the shower outlet is about 120mm over the pipe length.
A basin is next to the shower and releasing water from that, the water appears in the shower pot.
At the end of the run close to the stack is a toilet. Flushing the toilet results in gurgling at the shower waste. The toilet empties into the stack above the shower and basin waste pipe. The picture shows how it is laid out.
That stack is a stub stack about 900mm high which is sealed at the top. Could a lack of air in the stack cause the shower to go away slowly? It's worked ok for two years, though putting the shower on a very high setting it would back up when first installed. Now it backs up regardless after being in use for a few minutes. I'm trying to work out my best and easiest option. Any ideas are most welcome.
