Product review (2 stars): Diverter Valve Leaks After A Short Time
At first the product worked perfectly but after  3 months of use (far short of the 35,000 gal. filter limit) the diverter valve began to leak by.  Due to the valve leaking, hot water was allowed into the filter and now I am not sure if it is any good. The water still comes out clean and clear but the instructions state that hot water damages the filter. The Paragon Water Systems does not list anywhere replacement valves may be obtained nor am I able to find a support telephone number..
