Admittedly just looking for validation of my own conclusions, but here goes.
Heavy rain this morning which necessitated the bailing out of a garden pond. Whilst doing so it occurred to me that I hadn't checked the drain inspection chamber for a while, so I lifted the massive concrete lid and looked inside. I noticed that there was a minor but constant trickle of water through the underground gully, which I traced to the toilet pipe. The toilet wasn't leaking, or flushing and nothing but the toilet empties into that pipe. My conclusion has to be that there's groundwater leaking into the pipe from above, through a crack or open connector. Its way below ground so would take some effort to dig down to the pipe to effect repairs, but in the meantime I'll try to get photos of the inside of the pipe to assess the situation.
Question: if I find that there's a crack in the pipe and it hasn't partially collapsed, would it be a ridiculous idea to line it with plastic drainage pipe as a temporary measure until I can get round to digging it up? I guess it depends on whether modern plastic pipe will fit inside 1960s stone-glazed drainage. I do have some 80mm downpipe, but I guess that would be too small. Is there any other option that wouldn't involve either excavating the pipe or having it lined by a contractor? Its about 2 metres of underground pipework in total.
TIA
