Do you have an expansion tank tank  in the line leading into water heater? If not what is happening is that the water is no longer allowed to go back into the city supply.  You said that you had turned it off while you left so the water heats up and has no place to go so the preasure/ temperature P/T valve  opens and lets out the excess water from the expanded supply (heater water) that has no where else to go. It used to be that the extra expanded water just backed up into the supply pipe and back into the main. That is no longer possible in most places by the  National Plumbing code.    The answer may be to install the expansion tank into the incoming line. You can see then now at  all hardware stores where water heaters are sold.

If the water heater is working fine than I would not worry about the function of the water heater. What the problem may be is that some of your WATER LINES HAVE MOVED, AS THEY WERE NOT SECURED PROPERLY. The sound you may have heard was the Copper or PVC(Plastic) lines just getting back comfortable. I Suggest checking that your water lines are secured about every 3 or 4 feet with the proper ancjhor....Metal for metal pipe, copper for copper pipe, etc. Sometime as in my house, pipes are run through a hole drilled through a stud or a piece of wood, usually when hot water is run through this pipe. You can here an expansion of the water line interacting with the pipe expanding, if the hole in the wood was not drilled big enough......Experience of remodeling a very old house.......Joe
