Changed mixing valve now backflow is leaking
I replaced the mixing valve, the old one had calcium build up. I replaced with a new mixing valve that has check valves on both hot and cold sides. I notice there is a drip from bfp drain. Any idea how i can fix this? You guys think some calcium made it up to the bfp when took old mixing valve out?
