Been meaning to do this for awhile. Given the state of some of the other appliances where I'm renting, I'm guessing this hasn't been done in possibly years.

It took longer than I expected to break the vacuum and get tank to drain. I kept checking the (very) simple instructions in the manual. I'd done them all. I should pencil in a "Step 5: Patience."

Lotsa gunk came out, the drain hose and the open tub/sink HW taps. Eventually got everything to run clean.

My badge bit submission for flush a water heater. We live in a RV full time right now, so this task was performed on that water heater. We were getting sediment stuck in faucet aerators, so I figured it must be time.
When I pulled out the old anode, which I also replaced, lots of sediment came out. More was obvious when I flushed the tank out. Eventually subsequent flushes ran clear.

Had to change our rod so I figured I'd get two badges for it!

Here's my entry for the rod replacement for more pics if needed: https://permies.com/p/1291109

After I replaced the anode it became obvious that a flush was in order. Generally speaking there are no issues with the hot water, no off colors or smells. The point of the flush is to keep things in working order. Now that I'm done it's back to normal. The water runs clear and hot.

I got to do this one along with changing the anode rod. One thing I learned.....

To flush it well, keep the water turned on to the water heater.  Then when you open the drain, water will get pushed out along with the junk.  If you just rely on gravity, it might not get as much stuff.

The water was amazingly clean, I'm surprised.  It was a 7 year old water heater so maybe I actually did it in time...

Here is my submission for the Plumbing Aspect - Sand for Straw - Flush a Water Heater BB.

Wheaton Labs: Fisher-Price House
A new anode was purchased for installation so I decided to tackle both projects.  With the hosed attached and the power off, I opened the drain valve and checked the outlet.  By the time, I traveled from the water heater to the end of the hose it was running clear and there was no visible sediment at the mouth of the hose.  


To document the completion of the BB, I have provided the following:
   - a before picture of the water heater
   - an in-progress shot of you flushing the water heater
   - an after picture of the flushed water heater
   - a description of the previous and current state of the water heater

Time to flush the domestic hot water heater.  It is the upper tank and is electric.  The lower tank is for hydronic radiant floor heat.

I started this since I was doing the water heater anode replacement I thought I would go ahead and knock this out at the same time.

I did not notice any issues with the water but since the water heater was purchased in 2012 it was long overdue.
I did find that during the process opening the temp pressure release valve while performing the flush speed up the process.
I had to run it through 3-4 times after the complete drain to have the water come out clear.

Once completed I was able to fill tank back up and check this off my home maintenance list.

No issues with the water heater before, but I don't think it had been drained in a few years. Opened the ball valve and no water came out, too much sediment blocking the exit. I had to poke a hole in the sediment wall, then it started draining just fine. Opened the water supply after a while to push things along. Lots of sediment at first, but seemed to run clear not too much longer. Put everything back together, and it's working fine.
