Turn off power then turn off water and drain it once a year, or twice if you have really hard water. Replace anode rod every 3-5 years. And if the water heater does stop working. The heater element can be replaced for like $30. Just drain it, and always fill it before you turn the power back on.

I replaced my anode rod last year. My conclusion, the anode rod lasts the lifetime of the water heater, which is defined by the lifetime of the anode rode.

There's a fundamental design problem. The anode rod is installed in the water heater at the factory. Removing the rod requires that you have 5ft of clearance ABOVE the water heater. If you don't have that, it's darned near impossible to replace. So it's effectively a lifetime item.

That can be the case for many people, someone should design a collapsible one, or multiple part one that connects. allowing everyone to change it. I just bought a hybrid 80 gal, I only have 2ft of clearance above it. I'm gonna have to cut a hole in the ceiling and put in an access panel. glad mines in the garage lol.

When I pulled out my 12yo heater, the anode rod was nothing. There was nothing left.

I’m no plumber but I’d think it would be much easier to disconnect the water heater and tilt it sideways (after draining obviously). They’re not very hard to connect/disconnect and then you don’t need to cut a hole in your ceiling

With insufficient clearance it is my understanding that you break the old rod as you remove it and install a new segmented rod like this one... https://www.lowes.com/pd/Blue-Lightning-Rod-Original3-4-in-Hex-Plug-Aluminum-Zinc/5001418315?cm_mmc=shp--c--prd--plb--ggl--LIA_PLB_209_Water-Heaters--5001418315--local--0-_-0

Breaking it isn't easy. There's a 3/16 stainless steel core rod in the middle of mine. I had to hack saw it out while it was partially out.
Not worth the effort.

I know you probably meant “rod” instead of “roof” but it’s especially funny given the context of this conversation lol

Thanks. You're correct, and I fixed my comment!

That’s a good way to need a plumber. 90% of people should not attempt changing an aerator let alone an anode rod. Those things don’t just come out most of the time. Even if you do have clearance you should disconnect the water and gas lines just from danger of the water heater twisting when your wrenching them out. Everything on a water heater is technically easy but if you go into it thinking it’s going to be without having done it your setting yourself up for failure.

I’m responding to someone who already plans to work on his water heater and wants to cut a hole in his ceiling to do so
