Jandy Check Valve for Solar

[ChrisL]

I am replacing some plumbing on my pool, which includes the check valve for my solar panels. I was going to replace my ball check valve with a Jandy check valve, as I read here that they have significantly less resistance. However, Jandy instructions say that the check valve should be used in situations where there is the pressure of at least an an 18 inch water column after the valve. I have a vacuum relief valve, so after the panels drain, there will be no water pressure after the check valve. Is the Jandy check valve OK in this circumstance? Any other suggestions for a good check valve? I saw a "Magic Plastic" valve that uses a magnet to remain shut at a site, but never heard of it before. Anyone have an experience with it? Thanks

You should be fine with the Jandy valve. As long as the solar panels are 18 inches, or more, above the check valve you will be fine.
