1. In working on designing my small residential system (50k boiler/1500sq') and shopping around for parts, I've found backflow preventers ranging in price from $5 to around $1000... Anyone have recommendations for brand/model? Something reliable, long lasting, and potable water safe?
2. How necessary is it really to have an autofill/backflow preventer installed? I'm tempted to keep the boiler system separate from the rest of the supply plumbing. I realize this would require some frequency of checking the water level/pressure, but I've never had a boiler so don't really know how frequent this would need to be. Assuming no significant leaks in the system, once filled/purged/bled, how much water loss would be expected over time in a small system?
