This is good advice for all home owners.
Well, I try to do this about once per quarter, but in this case, it was approx 6 months since I last drained sediment out of our water heater. We have well and septic. But you can imagine how much dirt and grit accumulates in a hot water heater where this is never done. What are the benefits of doing this every few months? (1) I bet our HW heater lasts a few years longer. (2) There is less chance of that dirty water making to our spickets. (3) The grit could chew up rubber seals in valves and cause them to leak.
Yes, we drink this water, and cook, and bathe with this water. Been like this for 15+ years. As long as it settles and collects in bottom of water heater, it should be harmless. Draining it every few months is just a maintenance issue.
If you haven't checked yours since your water heater was installed, you might want to check it out of curiousity. Ours is in basement which has a walkout, so once a year I will just hook a hose to it and run the hose out the door and let it run for 10 minutes or so. The rest of the time I do what you see in these pics. Usually, about 1/2 of this tub fills with dirty water, then it clears up.
