Recently had a nightmare with a blocked soil stack at my elderly in-laws. It took a company 6 hours over two visits to unblock the stack and they have identified some breakage of the soil pipe bend at the bottom of the stack, which will need to be repaired/replaced and as it is an internal stack it looks like it will be costly! Fortunately, the soil stack ran through the roof and so was vented to the outside, which allowed access to unblock it.
That got me thinking about our soil stacks! At one end of the house is the house bathroom with an external stack, vented externally. Not a problem. At the other end of the house is the en-suite with an internally boxed stack and nothing to be seen on the roof, so I assume it is internally capped (with an AAV?). The house is 22 years old. Frequently, over many years, we do get strong smells in the en-suite and I guess this is due to the soil stack being vented into the roof space, rather than externally.
I'm now wondering if we should do something about this, but what are the options?
