    Check Valve Location

    Should there be a check valve after the outlet on the heat pump? Thanks

    Without a Trichlor feeder, there should be no need for the check valve.

    Even with the swg? If so I'll leave it out...

    That's what I'm getting out of reading. You should be fine without it with the SWG. If you had the inline chlorinator then you would need it. 😎

    Yup. Trichlor feeders make acid water, even when pump is off, which can apparently backfeed into the heater. The SWG does not make acid water and it does not generate when the pump is off.
