Works well but why is this a commonly replaced item?
Reviewed in the United States on March 27, 2019
We have had our iSpring RO system for 3 years and like it a lot. We lost pressure and determined it was caused by a leaking diaphragm in the tank. The replacement tank works well and fixed the problem, but I don't understand why so many tanks have to be replaced. It's just a rubber diaphragm in the tank - it's a pretty simple design. There really is no need for it to wear out in 2-3 years as seems to be the case for so many users. Why not use a thicker or higher quality material for the diaphragm and charge an extra $10 and then maybe we'd only have to replace the tank every 10-15 years?
