Hello
I have recently noticed a foul smell in the bathroom. The loo flushes the bath and shower drain and there don't appear to be any blockages so I checked the manhole outside the bathroom and some faeces were still in the chamber. When I flushed the loo and watched what happened, water sloshed around in the chamber and most flowed to the main sewer as it should. But some water stayed in the chamber along with the faeces.
The picture below is of the type of chamber we have. The pipe at 6 o'clock is the one through which the loo, shower and bath drain. The one at 3 o'clock channels water from the kitchen (washing machine etc). The other three aren't used and have plastic stoppers on the ends of the pipes. The pipe at 9 o'clock is to the sewer.
When the loo is flsushed water is sloshes around the chamber and some faeces stay in one of the unused channels rather than being directed down the pipe to the sewer. Can this chamber be replaced with one that only has the number of inlet and outlet pipes that we need or is this how they are all designed and is the problem the fitting?
