With about 200+ systems already turn on by us, and a couple hundred more already screaming that it will be 2-3 weeks before we get there, we get a serious cold snap. I can here the bonnets and poppets already breaking. What the hell can we do? It has been a seriously hot dry spring already, and people are anxious to turn on the systems, but many don't understand how to drain it. Then this crap moves in, and scares the heck out of me. I'm not so worried about the system breaking some parts, it's the flooding of the basement because it froze, broke, then thawed and dumped water out all day while they are at work. Either last year or the year before, all 4 of my suppliers, and Home Depot and Lowes, were out of bonnet and poppet kits late in the spring due to another cold snap. One of my customers that works at Lowes called me to see if they could buy some from me. Told them no, but was glad that I buy at least 60+ every spring.
