    looks more like the spark igniter wire was spliced.

    that heater should still be under it's 6 year parts warranty.

    that's an american appliance heater now owned by ao smith.

      The warranty expired it was a few months out of date according to the data plate and based on the date it was inspected by the inspector.

      The stickers on the heater say A.O smith.

      The owner had taken everthing apart twice and half azz put it back together. The control valve had dings on one side of it.....he said he "tapped on it" to try and get it to stay lit. A few years ago an A.O. Smith heater blew up in a garage and killed the homeowner.......same type deal,the heater would not stay lit and the homeowner and several plumbers had been tinkering with it.

      A.O. lost in court and so did everyone who touched it.....the owner paid with his life....the rest paid with big checks.

          Think the 3/8 copper gas line might have something to do with the problem

            That 3/8 was on the high pressure side. The gas was disconnected from the water heaters control valve. So no it had nothing to do with the problem.

                unless you have low sulpher natural gas, then that copper natural gas line would cause it's share of issues.

                No, it's not rocket science, it's plumbing and unlike rocket science it requires a license.

                  Mo, it's probably Propane but even so a 3/8 line is way way undersized unless the gas tank is about 5' away or less.

                    point taken on the sizing, but the gas valve says natural gas in the closeup pic.

                        A 1/2 flex connector that had been disconnected by the time the pics were taken. 1st thing i did when i got there was disconnect and cap the gas line.

                        Its natural gas. Its a 2lb system.....3/8 is plenty big enough.

                        Good eye. Our gas is ok for copper.

                          So there's 2lbs at the gas valve? Or 2lbs outside at the meter?

                            So there's 2lbs at the gas valve? Or 2lbs outside at the meter? cause 2lbs will blow the gas valve so you must be saying you have 2lbs at the street side and a regulator that drops it down at the meter, in which case like I said, unless that heater is less than about 5' from the meter there is no way that 3/8 is large enough.

                              Its a 2lb gas system. There is probably 35 lbs on the street side of the meter regulator and 2lb on the house side. Each appliance gets its on reg also to reduce the pressure
