Background: we decided 2 years ago to re-tile bathroom floor. & tiler insisted on the toilet bowl & washhandbasin being removed & replaced on top of new tiles by his plumber. Ever since then we’ve noticed a smell when we flush toilet which wasn’t there in the 25 years before that. There is definitely no blockage in the pipes as there’s only 2 of us in house & there is no evidence of blockage when flushed.
Another plumber came out last week to quote to replace our immersion tank in hotpress in the same bathroom, & I mentioned this to him & he looked & said that seal on waste is perfect, & reason for smell was due to the recent re-plumbing, which apparently is now set up such that whenever the toilet flushes, it sucks the water out of the washhandbasin U-bend, thereby allowing odors to come up through the washhandbasin drain & overflow openings.
I have to say I was amazed to hear this. How could a plumber set it up this way knowing this could be a consequence?
Before I ask my new plumber to reconfigure to fix this issue, can I pls check that this diagnosis is plausible & likely correct ? Pictures hopefully explain setup.
