Yes, the Hunter ICV <u>generally</u> tends to have a little bit less of quality soleniod than others, such as the Rainbird 100DV.
There are only a few ways to prevent it from comming...Make sure that there is no dirt or debris in the lines, no sand or anything in the valve, and make sure they are wired correctly. I have had a few fixes where the system wasn't wired properly and that's what caused the valve to not clost completely. There really is no way also to tell how often it will happen.
Very easy to replace soleniods......Search on the forum for solenoid and you should find something. If not, reply.
Thanks,
