Filling in old bog pipe

Just wanted to run this past the panel:Ripped the old bog (in the hall that used to be a bathroom) out today (hooray). Previously flushed with loads of bleach and conc HCl (not at the same time mind) to sanitise and clean everything.*Much* to my surprise, the pipe in the floor is plastic - as it is a 1950's bungalow I was expecting clay or iron. Must have been replaced sometime...But that's not the real point: I plan to fill it with concrete level with the floor ready to tile over the lot.1) As it is a plastic pipe, straight down with a rest bend about 18"-2' down, I'm thinking to throw concrete down until it fills the bend, at which point it will have enough friction to allow me to pile in more concrete to the top.2) The manhole is 4-5' away so no real danger of concrete getting into the main drains.3) The PVC pipe should provide effectively a DPM - though there is always a risk of water getting in from the other end, though I will be plugging that in the manhole too. The pit will be decomissioned completely once I prove whether a nearby gutter downpipe goes into it or not, because nothing else does now.4) I don't see much point in screed on top of concrete so hence the plan just to fill the pipe to the floor level.Anyone see anything wrong with any of that? Filling in bog pipes isn't something I do on a regular basis!TaTim

How old is your house? Shared private sewers built before 1/10/1937 are the responsibility of the local water company who must repair them free of charge.

The last government was in the process of extending this responsibility to all private sewers from next year. The enabling legislation was passed. I wonder what's happened about it?
