    Default Tank-less water heater PT valve.

    Inspected a 140,000 Btu Noritz unit. 6 years old. No PT valve. My opinion is that it needs one. Any comments?

    I can't say for sure if it "needs" one from a physics and safety point of view... but it needs one from a code and all manufacturers instructions I have perused.

    There is a brand of tankless, Titan is model name, that doesn't have a place for a relief valve. I've not been writing this up but have certainly wondered about it.

    Look at page 19 item 10 in manual http://www.noritz.com/commercial/fil..._NCC199-SV.pdf :

    In general if anything generates hot water or steam it needs a press relief valve.

    Typically a valve such as the Webstone 54443WPR is used, which has a location for the TPR valve.
