Anyone any experience of a domestic pumped sewage systems where

No personal experience but I know a cottage up
the top that has one. It is relatively trouble
free but if something does break down, (or a
power cut lasting a few days), then it is panic
stations in case the holding tank overflows.

We used to be on a septic tank and (imo) if you
have any sort of private sewerage system then you
are almost certain to end up diy'ing the regular
maintainance and various repairs. No great problem
but, (like exhausts on cars), they always seem to
need working on in the depths of winter.
