I placed an air hose adapter in underground control box near my shop, with a gate valve just before hose adapter. I run out 50’ air hose from shop compressor, dial back compressor to 40psi, and manually run thru valves for winter blow out. Dies not take very long. I simply blow each zone until I see air at each head. Compressor keeps up fine. Been doing it this way for nearly 15 years and i have never had sny frozen breaks.
I only turn it down cause im afraid ill blow the pop up riser out of the groundI do the same except leave the compressor at its normal 150 PSI. Sure gets the cobs out of the gear drive heads!![]()
We run 12 zones equi-distant from B-Hyve wi-fi controller.
The 12 zones span 650' in either direction.
Each valve off the main supply line controls 4 (360 degree heads) 80' apart spraying back to one another.
There are two other zones on another B-Hyve controller for the homes.
I set several programs for each of the zone for different days and all from my iPhone through an app.
My wife indulges me with tech but as we age it just gets harder to do all these things manually.
