hi all
So I moved into a new 3 floor house couple of weeks ago
I'm not a trade but reasonably competent around diy etc
However this I've not come across - whenever we use the upstairs bath or shower - after 5 minutes or so the downstairs toilet starts bubbling with air coming through and if prolonged use, it will empty below the waterline -
Probably because the air bubbles are Forcing water down the waste pipe leaving a drop below the line
Doesn't happen when flushing toilets as I guess that's only a small quantity of water compared to running a bath or shower
We also noticed when we first moved in the middle floor toilet was completely dry but the house had been empty 2-3 months before we moved in
- no evidence of any leaks anywhere
Any ideas?
The house is about 10 years old and from my observations, doesn't appear to have had any obvious or major plumbing work since being built
Thx all
