How to find PVC pipe underground

[pg325]

I have a block somewhere on the rain water pipework, a drain on my drive is backing up in heavy rain.

I have a 15 metre drain cleaner that I can attach to a jet wash bit I know there is an inspection cover buried in the front garden somewhere, finding this will hopefully allow me to get the rods into the system and clean the blockage.

Any idea how I can find the PVC pipe?

If the inspection cover is steel/cast then metal detector may help locate it, otherwise water divining, an educated guess or good luck are the alternatives....

Are you sure it is not a soak-a-way?

Your drain attachment for the karcher is not worth a light.

I got the plans from Wessex Water and they show a main running through the drive out to the main road.
