Where can i get a good filter with low pressure loss, I'm putting it in front of my DCA, and can some one please describe to me what non toxic means? I mean im gonna put feritlizer on the ground and water it, not actually inject it into the system? Should i be worried about my health? Also What is the deal with, regular dca's and lead free dca's! Thinking of useing a Febco 850, they have both type?
California likes lead-free plumbing, and what California wants, the market will provide. By the way, the Febco 850 is always referred to as a DCVA, and not by any other abbreviation.
A simple Wye Strainer is all you would need upstream of a backflow preventer, if you are on city water.
