Toilet Blocked - Fills Up when Toilet on Floor above flushed

[RK_London]

I have a downstairs blocked toilet. Tried plunger but no joy. Water does drain away slowly over many hours. When I flush toilet directly above on next floor notice downstairs toilet filling up.

Not sure whats going on - next step will is to get a flexible coil from Wickes use it on downstairs toilet.

Would appreciate any help understanding what's going on.

Thanks.

Lift outside manhole cover and check all is clear inside for starters.

Don't think I have manhole cover on my property. I forgot to mention I have a 3rd toilet on my extension and that seems to be working ok.

Water from downstairs Toilet is slow to drain - Restriction between toilet and sewer, check manhole serving property.
Water from upstairs toilet causes water in downstairs toilet to rise - Restriction between downstairs toilet and sewer, check manhole.
Water from third toilet is uneffected - Different branch (?) so use that one for now.

thanks - will try to figure out where man hole cover is.

Knock on doors, see if a neighbour has slow draining toilet(s).

Tried neighbours - nothing there. Just used 2 metres of drain coil down toilet but made no difference. Maybe time to call in Dyna Rod

Avoid the florescent vans, they're not called 'Dyno Rob' in the trade without reason. I'd speak to Andy above, @HERTS P&D first, see if he covers your area.
