So I watched the macna video about plumbing, and it reminded me to clean my check valves. So the second one was only on for about 6 months, and a small amount of time alternating in vinegar and bleach took care of that one, but the other has some built up calcium deposits. Just wondering about the rubber gasket and a prolonged bath in vinegar? I had a spare, so swapping one out while the other soaks isn't an issue, but just wondering what other people do?
