Funny I’m seeing topic, as I just flushed my hot water tank today in anticipation of my planned move up to Yellowstone next week.
I’m full time, so I don’t flush after every trip. But I do flush it every 6-8 months or so. Not in preparation for winter or anything... but to clear out the white calcium deposits that build up in there, especially if you spend time near hard water like I have this winter.
I’ve here on the Colorado River since mid-October... a notoriously hard water area. After draining the tank, I then spray & flush it out using one of these wands by Camco:
It’s amazing the amount of small white calcium pellets that shoot out of that thing, along with lots of milky white water on the first flush. So much that it scars the wheel skirts with white streaks that I have to clean off a few hours later with a bit of CLR.
THAT’S why you wanna flush the tank often... to get rid of the calcium.
If you wanna see what I mean... just go to YouTube, and watch a few videos of it.
Oh yeah... one reminder when you do this: TURN YOUR HOT WATER SWITCH OFF!!!
Just had a friend of mine burn up the heating element on his because he forgot. Cost him around $1,000 to replace the unit because of a brain-fart. The heat element will fry itself out if left on with no water in the tank.
