My water heater is making popcorn sounds?
The water heater is a "Alliance" kind and its approximately 22 years old. On the exterior of the water heater there is calcium & soap scum build -up around it.
What do you suggest on what option should i do about the popcorn sound?
Do you recommend a water heater replacement?
Do you recommend for an expert to come by my apartment and try to repair it?
I am very confused!
Thank You for your best advice answer.
