Once in a while I have to ask "are you serious"? If there is a device that can determine whether a line will bust or develop a leak in the future I'd love to know where to buy one.

Received a more constructive answer somewhere else: install a main valve, connect it to the pump terminals of B-hyve. Then you have redundancy and a smaller probability that two things will break at the same time

Or you can just regularly take a look at your water meter, which will show movement with even the tiniest leak.

if the failure happens when I am not around (vacation) then the above recommendation can't be applied

Having a main valve that is failing at the same time with a pipe or manifold valve failure is very unlikely.

The main valve will make sure that even if the system fails downstream of that valve the system will be off excepting the short time when the watering program kicks in. I can live with that risk which is far smaller than having the irrigation system all the time loaded and under pressure (when there is no main valve for the system)
