Tired filling with fresh? Get this bargain on a complete auto top-off setup. Includes legendary Tunze Osmolator controller. Detects lower water level with both an optical sensor and float switch backup. Slowly pumps fresh into your tank from the included 5-gallon reservoir. Reservoir already has a float switch and 1/4" inlet installed and is ready to be fed from your RO/DI system.

Don't have an RO/DI? I'm selling that too, look for it in this forum. Buy them both for for $350.

I'm in Longmont for pickup. I'll be in Aurora this weekend (2024-04-27,28), so I could deliver almost anywhere in the metro area this weekend.
