We had some garden work done and while digging they went through the oil pipe (despite us instructing to hand dig in that area as there are multiple services in that section of the garden), the oil pipe was not quite where it was expected to be and was not actually all that deep down so to be fair it could have been easily done as there was some dark green tape but no evidence of there being the depth of the sand bed or plastic like the Oftec advise states - all of the pipework was installed newly when we had the tank moved a few years ago so we were surprised to find it so shallow.
Anyway we managed to get an emergency fix, but before we cover over the pipework which had to have the damaged section cut out and a new piece joined with fitting, we just want to make sure we can inspect it and keep an eye on it.
I read a recommendation in an old post from @oilhead of "a piece of drain pipe with a horseshoe cut out of the bottom to let the pipe pass through with a cap on top.
If it is necessary to bear a load, then a stop tap cover is better." and wondered if someone could just give me a diagram of what this pipe would look like exactly as I'm struggling to visualise it? and is there a recommended dimension of drain pipe to use? I will get a stop cap cover I think just to ensure some resilience.
Also its a few years since the pipework was laid but is there any come back for the fact that it wasn't actually anything like the recommended depth and we paid a lot of money for the complete installation of the new tank and pipework at the time, I'm now a bit concerned that if all of this is actually as shallow and none of it has the sand bed, plastic and only just has warning tape so close to the surface then its very easy to accidentally dig through it.
