    Testing question

    If you test after pump has been off several hours, and then test after running pump for 30 minutes, should your numbers be very much different??

    FC showed 2 with no prior circulation and 5 after running pump. Second time this has happened.

    Re: Testing question

    We always suggest testing after water has been circulated.

    Example: Does your bath water cool off at the top faster than the bottom?

    Because you should be circulating all night when performing that test when doing the SLAM.

    Re: Testing question

    What if not during SLAM, just testing?? I thought I had all this, but I find myself second guessing myself.

    Re: Testing question

    I do a OCLT about once a month. I just leave my pump on for that night. It makes me happy so...
