Bad smell from bathrooms

We have an ensuite and house bathroom that seem to suddenly and at random start to smell like drains. This doesn't happen all the time and is usually either 1 bathroom or the other rarely both. We now seem to be having a similar problem with the kitchen sink. Currently we manage to sort it by running taps and putting bleach down the plug holes but would like a more permanent solution. Can any of you suggest a cause and solution? Many thanks

This sounds like you are losing the seal to your water traps.
This could be caused by the seal drying out in hot weather (rare in this country).
Or induced syphonage if the waste system is poorly designed/installed or vent pipes are blocked.
The installation of antisyphon traps could resolve this issue and making sure all vents are clear. If the vent pipe is internal a Air admittance valve must be fitted to stop the ingress of foul air into the room.
