Review on Wilkins RK1 720A Repair Kits by Joshua Albright

I was watching a video showing how to rebuild a Zurn 720-A vacuum pressure switch. It looked so easy I figured it would solve the rattle problem I had when my irrigation system started up in the morning. I know you can ask someone to test the system, but why pay $100 or more to test it when you can easily replace it for half the cost? The kit was perfect. It contained all the details I needed. If I hadn't taken the brass hood down to the basement to clean it, the whole job would have taken about 10 minutes (I'm sure I could restore my neighbors in less time). My irrigation system is quiet and I don't have to worry about water flowing into my home water system.
