Schulze Pretreatmaker Troubleshooting Tips 3/4, III/4 Tips After Heavy Use or Buying Used

[@BootlegCraig]

What tubing is used in these machines? Thinking about just replacing it all... bought a used machine and the lines are caked in dried salt or pretreat.... feeling a little defeated as I can't find a tech in my area nor many videos online for how to really disassemble and clean these units to "restore" them.

Don't know sizing but if the machine is that bad you could replace all the lines or clean them out with hot distilled water but your pump and solenoids will definitely need to be replaced. Possibly the valve that switches from the jugs if you have the 4/IV. If you need help we have a paid support plan that can help you to understand the machine. Its a really simple machine once you learn how it works.
