I've been having some work done for ground movement on the home insurance. One of the recommendations of a drain survey was to re-bench/channel in a manhole on the driveway as the existing terracotta channel was cracked and leaking.
When the insurance-appointed contractors were finished (who were from out of town), they showed me their handiwork and I immediately noticed that the new channel was sitting slightly proud of the upstream pipe. I pointed this out and asked if this would be a problem and was told it would be absolutely fine and that waste would flow over it no problem.
I've inspected it in further detail today, and while I was pleased to find no backlog of turds, it does look like toilet paper and leaves are snagging on it slightly. I've also noticed that there actually appears to be a horizontal gap of approx. 1cm between the two sections, although I think the new channel is possibly sitting on a section of the old terracotta channel or pipe, as it feels like terracotta beneath it. I would estimate the base of the new channel sits proud by 1cm.
The work was done by two lads in their early 20s, nice enough guys but I got the feeling they were wanting to get home for their tea. Just thought I would query this on here as I have no idea whether this is normal or not.
