I close the water heater check valve and put plug back in it then go back in and bypass the heater. Then I turn pump back on and starting with the closest faucet run the hot and cold until they both run pink... Moving to other faucets ,shower and toilet .... And if the antifreeze jug runs out I put another on and open a faucet to get it to begin priming ... After I have run all faucets and I know I have antifreeze from running them in my j pipes I switch my pump inlet hose back to the tank inlet and call it done .... I don't think I am missing anything but I am sure someone will let you know if I am lol
I started much like that only followed with blowing out everything then pumping the pink through everything starting with the ODK and forward. I then went another step further and blew it all back out and into the traps and tanks. Took 4 gallons, but that is due to my expansion tank and filter holding alot upon initial prime.
The big hang up was the pump priming. Have to remember to let the pressure out on the other side to get it going.
