Holy fuck that seems like a tedious, difficult, messy job. I’ve also never heard of it, and I feel like the homeowners I know would have bitched about it to me before if they had to do it. I looked it up, and there’s all sorts of scenarios in which they might not have to do that (anode rods and tankless water heaters both seem pretty cool and there are services for it), but I might just send out a couple of texts. Water heaters are nothing to fuck with.
If it has a valve on the outlet of the water heater, you can close that and flush cold water through the heater and out the bottom drain by opening the drain. This will also have more pressure and volume of water to flush with.
