Water comes out at 0ppm. Tank does exactly what it should.

Straightforward and works exactly as promised. I fill from the tap, the resin strips the minerals, and the water comes out at 0ppm – my windows dry spot-free with no effort. The tank is heavier than it looks once it’s full, so don’t plan on carrying it far. Resin lasts me about 6 weeks of residential work. Delivery to PE took a bit longer than the 3-5 days they advertise, so plan ahead when you need resin.
