    That is like saying you went to Home Depot and the guy in the aisle said it was done correctly. Do you REALLY believe that someone working the Winnelson counter actually worked as a plumber and then "downgraded"?

    HAHA! No, my point exactly--and also that my plumber buys stuff there! What else are they going to say And hence why I came to this forum! But truly, saying that any licensed plumber is great is like saying every licensed general contractor is great. I mean, no one's EVER had any problems with one of those, right? Here's the rub in all this...this was inspected and passed! I'm glad I paid for that...

    I don't believe it's in the code book that the check valve is "required" on the recirc, but if you leave it out, the cold water goes backwards up the line.
    You know that now too. And I'm guessing your plumber is putting that new knowledge on his check list.
    We install the check valve, not because it's code, but because it's a better way. I use a spring check, as they make less noise while the pump is running than using a swing check.
