A few years back I installed a sprinkler system with a valve that
didn't require electricity and would
change zones when the pump switched off.

We're in a new house in a different state and I'm thinking about
putting in a sprinkler system. Went to the local Lowes and couldn't
find the same valve.

For the life of me I can't remember the make or model of the one I
installed in Florida.

I've tried looking online but so far haven't found it either.
