Hello all,
I have a soil stack to which is connected the waste from the bath and basin. Directly above this, about 8", is the waste from the toilet. At the top of the soil stack is fitted an air admittance value.
The bath has a shallow bath trap fitted and the basin a standard bottle trap. The problem is that when the toilet is flushed a few times the water in the bath trap is sucked out. This leaves a very unplesant smell in the bathroom.
I was thinking of fitting the waste from the basin and bath lower down the soil stack to overcome the problem of siphonage. Will this work?
Obvioulsy I only want to try this once as it means cutting out holes in the soil stack.
Many thanks.
