We have an AO Smith GNR50-200 water heater that’s 10 years old. We also have a recirc pump & valve.
Based upon testing, no water softener is required for our city supplied water.
The water heater has been making popping noises whenever hot water is used. Other than that it has worked very well.
Would draining help? Is there any advantage to replace the factory drain valve with this one?
