My sewer is backed up to the first floor toilet, the ground floor toilet is working OK.
When I flush, the sewage goes into the shower.
The stack for the first floor toilet has a polyvalve on it, and when I took this off, it started flushing properly, but once back on, it immediately started flushing back into the shower.
I think this means that the there is sewage in the stack which is not draining when I take the polyvalve off.
We spoke to the housing development customer services and they unblocked the sewage pump and it's now flushing better than it was and it's not going into the shower anymore. Although it's still quite a slow flush.
I'd like to know why the ground floor toilet isn't affected, when the sewage is backed up to the first floor, way above the ground floor toilet.
I'd also like to know how the sewage can back up to the first floor.
This has happened three times in 20 months, is it likely to be a faulty sewage pump or a problem with the pipes.
Thanks.
