That’s suks my hometown in Colorado we all have automatic drains in our systems so we don’t have to do nothing but turn off the water and we are done we don’t have to blow it out or nothing every house is done like that even the city recommends that we do it with automatic drains I would hate to blow out my system of 24 Zones
I’ve lived in Colorado my entire life and every house I’ve worked on has never had an automatic drain system. They are not common here. If the pipes are deep enough, then you can get away with not blowing out but you will eventually have a crack somewhere in your system. I had about 19 zones on my last house, and it didn’t take me too long to blow it out maybe 30 minutes.
