@cfldriven - My setup is similar to this, but I have a filter in front of the cold water input. So in order to clean the unit, I assume I would turn off the cold supply before the filter. Then turn the second cold valve like in your photo to the closed position, connect the hose to the service port and the pump. Then on the hot side, close that valve, then connect the second hose to the service port, and then place it in the bucket. Then turn on the pump and flush. Is that correct? Thanks for the video!
@@cfldriven Thanks for your quick reply. I just finished the flush and water did not squirt out when I opened the caps. Just some water leaked out slowly.
So, it's not that different from descaling a Cleveland Steamer Boiler, aside from the inlet filter, and using vinegar rather than descaling fluid! Thanks for an informative video!
