I just DIY-d a MF film washer using some PVC tubing. Surprisingly easy but while testing it in my basement slop sink I realized that while the cold water is crystal clear, the hot water is pretty cloudy. I have an older home so, who knows, there may be some sediment in the pipes. The slop sink is the only faucet in the house that is threaded to accept a fitting to run a hose to the washer. So the best I can do is cold water for the wash cycle. Wondering if that will be detrimental.
Water temp is 62-63 F > 17-C
I went down this rabbit hole because I've noticed some spots on my sheet film developed in the Stearman tank and the advice was to wash outside the tank. I don't get the same spots on my MF film in a Patterson tank; I built the MF washer as a test-build to see how hard it would be. The rest of my work is done in the kitchen (less dust than basement) using filtered tap water that's usually 1 degree within 20-C. The kitchen faucet is one of those fancy-pants spray heads; no way to connect a hose. Adding filtration to the slop sink is not a viable option.
Maybe I'm missing something......or over-thinking.
I found some 4x5 washers on the auction site but don't want to spend the $$ if water temp is going to be a problem.
