Sorry if this question has already been asked but I have a random question about my water heater to see if this is anything I need to be worried about. To start off I live in an apartment complex and my water heater is in a locked utility closet. I have noticed everytime I flush the toilet and make my way to the other end of the house I hear a "clicking" sound coming from the heater as the toilet fills back up with water. That is the ONLY time I ever hear the sound is right after a flush and it stops right after the water stops filling the tank. I have a gas heater and the sound is almost like a election lighter on the stove top when you turn on a gas burner. However I do know the water heater has a pilot light and it is working just fine as I hear it ON (the gas burning sound) every once in a while. Any ideas what might be causing the clicking sound?
UPDATE 2/28 - I just checked and the water in the tank is cold, both after sitting all day and right after a flush so I dont think it is hot water coming into the tank. I'm kinda stumped right now but I am off on tuesday and going to make an appointment to see if the maintenance can do anything to fix it?? hopefully they can.
