      A:  I believe so. Over time it's likely Marathon changed suppliers.

        A:  We installed the same one just before the heater , there wasn't any before.

              A:  A test stand is used. A test likely can only be completed by a professional.

              by|Feb 2, 2018

                A:  Mine had a small leak, which was my indication to change. If it isnt leaking, i wouldnt mess with it. With that said, im not sure of a way to actually test if it is functioning correctly.

                by|Nov 13, 2022

                  A:  I would recommend contacting our tech support and warranty department at 866-279-4566, as they would be best suited for assisting you with this, granted the heater is still under warranty coverage they would also be able to get you a replacement if that one is broken.

                      You Don't Need It
                      Great valve, because it's the same one that comes on the Marathon water heater, so I don't understand why Home Depot suggests you purchase it. Waste of time and money in buying and then subsequently having to return it.
