    SWG installation help

    I have a Circupool RJ45 ready to install. So far I have mounted it on the wall. I don't have alot of room betwwen the wall and the plumbing and so I am somewhat limited by the legnth of the cord. I have a Pentair Mini Max NT heater and I spoke to technical support. They said I should put a check valve between the SWG and the heater. Do I really need this? What type of valve do I need? Thanks.

    It common advice to out a check valve between the swcg and a heater to prevent water from the swcg from flowing back into the heater in case something fails. I'd use a "Jandy" style check valve because they have lower head loss compared to other types and they're rebuildable.
