Review on Enhance Your Water Quality with the ISpring 3 Stage Filtration 20 Inch Sediment System by Kathy Genova

Excellent product. There is a very noticeable difference in water quality from drinking to showering to washing clothes and dishes. The product is big, so make sure you have enough space to place it. I added a shutoff valve to the water line before the filter, added a regulator (our pressure was 150psi! Filter range 40-90psi. I adjusted mine to 65psi), installed a water level gauge right after the regulator, installed a bypass for that system (just in case), then another pressure gauge to control the drips before and after the filter (should help determine when it's time to change the filters), and finally another shut-off valve after the system, so that the filter can be isolated for filter changes or other maintenance (only with shut-off valve in front of the filter, be prepared for all the lines in your house to flow back into the system). This is a project that requires quite a bit of know-how. Expect to spend a few hours on this, especially if your situation is similar to mine (my plumbing came to the house at the worst point on the subway, so I rerouted it so it was closer to the entrance). If this seems intimidating, I would have a professional install it. But again, this is a great product and a great investment for your home. It's worth it!
