Empty the bath, toilet gurgles (air coming back up).
Flush the toilet and the bath 'spits' water (lovely).
Happened one day last month. Flushed the toilet a few times and ran a couple of baths through the system and it seemed fine.
Now its back (past 3 days) and it won't shift.
Checked the soil manhole (big concrete manhole in the back garden) - had about 1 inch of standing waste water in it - couldn't see the channels at the bottom of the hole.
Got the garden hose on it and with the water pressure could just see the 'floor' of the hole.
Left the hose in for a while to see if the water level would rise (as if there was a blockage) - but it didn't - the water stayed about an inch deep.
Ran a few full baths and flushed the toilet a few times to see if I could 'flush' any partial blockages out.
Strangely, also checked the manhole at the same time to see if the water level had risen - as I'd put a load of water down it.....but it was at the same level - still about 1 inch deep - it hand't moved!
Does it sound like the soil down pipe, or the main sewer?
Any help appreciated!
The other two toilets are fine, but I'm pretty sure they go to a different soil chamber (front of the house).
I've also tried (just for a punt) some 'drain cleaner' and also some 'drain unblocker' in the hope they might corrode a potential blockage.
Tried plunging, but hardly anything happens (just get water from the bath/sink overflow).
Nothing 'odd' has gone down the system from us. Its the spare bathroom which we hardly use.
There's no service access on the soil pipe either - as it's an 'inside' soil pipe, all boxed off into the interior wall. :-/
I can see this being expensive to sort
