Thanks for the reply. in the bottom of the RPZ, it says 1, is that the FE860-100 model
Hi all: I completing my winterizing late in December, the guy who did it told me that the RPZ might be damaged. It is a Febco 860U. My question is if there is an easy way to determine whether the RPZ in functioning. He said it costs $500, is this a reasonable quote to replace the RPZ. Also, whats the best place to make a purchase online for a RPZ? I appreciate any help I can get.
