[QUOTE="Catt57, post: 3576156, member: 34578"] OK, Wall of info incoming. I'll try to break it up a bit. --------------------------------------------------------------- The anode rod is “self-sacrificing” and will continue to corrode until eventually it must be replaced. When there's no sacrificial metal left on the anode, the tank can rust out, eventually causing it to burst. Also consider (while no one actually replaces the things like they should), they are only expected to last around 5 years. So at 17 years I'd say it needs replaced. Hence the probable need to also flush it out. It just might be worth have a trustworthy plumber look and see if it actually needs replaced or just needs a little maintenance. Last place I lived the tank was flushed and the rod checked every 2 years. Replacing the rod as needed. That tank was 35 years old, never had any issue with it, and was still working when the house was sold. Sediment on the coils can insulate them causing it not to heat the water properly. FYI, A simple flush is easy. Turn off the water and gas/electric to the tank. Open the hot water faucet in the kitchen to allow air in. Drain it (Garden hose usually fits on the drain spout). Leave the drain open, turn the faucet off and the water on and let it run until the water coming out is clear. Then close the drain, turn on a hot faucet in the kitchen again and let that go until all of the air is out of the system. LASTLY turn the gas\electric back on and let it go back to heating your water. [/QUOTE]
