Hi I need to flush out the water side of my dometic a/c units. Does anyone have any suggestions as to what sort of chemicals to use obviously I don’t want to get to aggressive .
I assume you mean the closed water cirquit to the chillers ?
I used just tap water, untill the water coming out on the other end was perfectly clean,
after finishing that, I filled the cirquit we premixed cooling liquid
Rydlyme, diluted as stated on the bottle then pumped around in a loop with a small pump.
I plan on doing mine soon with Barnacle Buster as I can’t seem to find Rydlyme in Spain.
