Do you need a check valve on the feed line to any boiler in NYC? Is it code?.....Paul S

    Not sure about New York City/State, but...

    In the jurisdiciton I work in, it requires MORE than just a single seated check valve. It requires (residentially) a double check with an intermediate vent, and if it is commercial project, minimum requirement here is a reduced pressure principle back flow preventer.

    Best to check with the authority having jurisdiction. Also be aware of annual testing requirements.

    It's not so much a case of "You got what you paid for", as it is a matter of "You DIDN'T get what you DIDN'T pay for, and you're NOT going to get what you thought you were in the way of comfort". Borrowed from Heatboy.

    On steam

    You need backflow and a check Valve below the waterline

    Type of Backflow depends on size and whether you're using chemicals

    If you can email me I will send you Latest codes that I have (2009) as well as contact info for boiler division

    Boiler division Usually only inspect if it is mixed-use Or more than five families
