Product review (5 stars): Works great for me
I was having a hot water problem. Our water is not terribly bad, but with sediment built up in the hot water heater, we were getting deposits on our dishes. I bought this filter and installed it, and that problem is gone. I had one minor problem. I could not get the outlet fitting to stop leaking. The brass fittings they provide are so sharp, it was tearing the teflon tape to shreds (and I may have over-tightened the fittings). Once I added about 4-5 wraps of my own tape, all is fine. It is very nice that they provide everything you need to install it, including brass adapters for various size water lines, and an additional supply line that you will need between the filter and the dishwasher.
