Popping noise

[sctclimbs]

Was talking to my sister about my WH problems that you guys helped me with week or so ago. She was telling me that her WH makes 2 or 3 popping noises each time a hot water tap is opened. It is 3 years old. She is a little worried about so I thought I'd put it out there and see what you guys thought.

It has a mineral build up at the bottom of the tank. It could use a good flushing.
