    OCLT Question

    Hi, I'm new to the forum and have a question about the OCLT test. Should the pump be running overnight to perform this test? I assume yes.

    Re: OCLT Question

    tim5055: Based on your response to this post I reread the OCLT directions on this page:

    It doesn't mention running the pump during the OCLT. I guess it is assumed that if you are SLAMming then you are running your pump. But if you're doing the OCLT to see if there is a problem or not you wouldn't necessarily be running the pump. Maybe one of the moderators could update that page to reflect that the pump should be running during an OCLT for us newbies who wouldn't know that.
