Hello all I will be as brief as possible.
The flat i have rented has a stale drain smell in the kitchen living room. Second floor of 4 story block built in the 1980s. Stack pipe runs inside in corner of room boxed in behind tiling.
After checking traps, cleaning the dishwasher and the washing machine I was pretty certain that it was from the stack or the waste. The system is closed from where the trap under the sink to where it goes in to the stack somewhere in the wall. 1 month later 3 plumber visits later a drainage company pushed a high pressure jet up the stack from the access cover outside the block. They claimed to find a blockage and cleared it. On going in to the kitchen there was water on the work surface in the corner by where the stack runs behind cabinets and tiling 5 feet from the sink and in the form of a puddle. There were little bits of plaster and my interpretation was that the high power jet had sought out the crack/break/leak and with sufficient pressure then knocked out the plaster and dumped a little water on the surface. The void the stack runs in has sound lagging, so perhaps quite an achievement. 3 hours later I noticed a damp patch on the ceiling. It is suspended plasterboard with concrete ceiling/floor above. A sink appears to tee in to the stack just under that concrete floor above.
Everyone now saying it's fixed smell will go. I'm thinking if water can get through so can air and smell. I'm also thinking that in HK SARS 2 spread through their high rise dwellings due to this type of thing. So. If they removed a partial blockage should I fret about the water jet having pushed through the wall and left a damp patch on the ceiling. All thoughts most welcome. Thank you
