Regular drainage of HW heater, or leave it alone?

I always hear mixed opinions on this, is it best to just leave it alone, or is it a good idea to drain it every now and then to clean sediment? When I lived at my parents' we never did it, and never had issues. There's one time where the tank did get a leak and have to be replaced, but I doubt that was because we never drained it.

My hot water is clean as far as I can tell, so any real advantage to draining the tank?

Any newer water heater has a feed pipe that is curved a bit--kind of makes a whirlpool in the bottom of the tank--keeping the sediment from forming.

I don't like flushing the heaters. I've seen more problems caused by opening the spigot than leaving it alone. ----Mike---

If sediment does collect in a gas water heater tank, that forms an insulating layer at the bottom of the tank and the tank bottom itself gets to a higher temperature possibly damaging the glass layer and letting corrosion set in sooner.
The good conscientious technician or serviceperson will carry extra oils and lubricants in case the new pump did not come with oil or the oil was accidentally spilled, so the service call can be completed without an extra visit.

I have a 5' hose attached to the drain and whenever I need hot water in the basement I drain it out of the heater.

Interesting idea, I should run a hose over to my basement sink
