I am quite pleased with the purchase, I ordered this to replace the original control valve on our water heater which is about 8 years old, and replaced the spark igniter as well since both were giving me issues at the time, fortunately being a licensed made it easier to do the install of both the control valve and the spare igniter, I haven't had any issues since also had to turn the temp down on the new valve wtr is definitely hotter with the new valve.
