I posted this on the "All", but received no comments, so I decided to try here. I also edited it for some errors.
I figured out an efficient way to reverse flush just the HWH, when the water in it has become stinky.
1) Heat up the water. This will tell you when you have displaced all the water when flushing by the temp. change.
2) Depressurize the system by opening all the HW facets.
3) Connect a washing machine inlet hose, (a 6’ length with two females) to the HWH drain valve.
4) Connect a clean water source to the washing machine inlet hose.
5) Turn on the water and check for leaks.
6) Open up the drain valve on the HWH.
Water should now be coming out all the HW faucets.
7) Let run until water is cold, and then some more.
8) Turn off the valve at the HWH.
9) Turn off the water source.
10) Disconnect the water source from the washing machine hose.
11) Drain the water out of the washing machine hose.
12) Use a funnel and pour a cup of Clorox into the hose and connect the water source back up while keeping the Clorox from running out by keeping it elevated.
13) Turn the water supply on again and check for leaks.
14) Turn the drain valve on the HWH on for just a few seconds and then off again, enough to displace the Clorox in the hose into the tank.
15) Turn off all the HW faucets.
16) Disconnect the hoses.
You're probably wondering why go through all this?
I did not want to run my fresh water pump to death flushing out a 20 gal. HWH. I also just wanted to inject the Clorox in higher concentrations in the HWH only, the cold water was fine.
Hopes this helps others.
