The water level in my downstairs wc pan is below the normal level - (accounting for the bend). This means that smelly air from the soil pipe / drains is coming up.
When I flush, the level in the pan returns to normal - then goes down to a low level again. And occasionally makes a gurgling sound , even if I haven't flushed it for a while.
It's like there is a vacuum in the drains.
Is this 'back-siphoning' ? Any ideas on what I can do ?
Thanks, Peter
