Can anyone enlighten me as to the best way to flush/descale the AC cooling lines. I don’t have access to the port side of the boat due to our slip setup. Would like to rig up a loop to run a descaling solution. Since we have two discharge lines curious where to feed and return the solution.
What I have done is to run Barnacle Buster into the lines, shut the pump off and let it sit overnight. After flushing it the next day it seems to do the trick. Not as complete as creating the loop, but it seems to work well enough.
