Good filter?
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?
