I received the 'kit'. I am going to go install it in the next hour. I hope it works.
I have a bit of doubt however, I test the old and new Thermocouple(TC) with the multimeter, and the old one hit around 22Mv faster than the new one did (in about 1 minute)! I heated the tip of the TC by applying a flame from a BBQ lighter. They both ohmed at around 0.3ohms!
I have been tricked by mulitmeter tests, in the past, into thinking something was good, and found after buying a new part that the old one was indeed bad (even though it tested good) - for example a coil pack on my car.
I don't want to have to order a valve, and wait for that to be shipped, before I can get hot water again!
