Tunze Osmolator problems

[FishyFishy!]

Yup. This is common IMO. I've had numerous Tunze's, and have always had pump problems, and one controller failure. You can usually pick up replacement parts at J&L.

I got frustrated with the Tunze, so I went for the cheaper JBJ ATO, and used a Maxi-Jet 1200 pump... Ran for years on numerous systems without a single issue. Biggest piece of advice with any mechanical float switch setup is regular maintenance.
