I actually surprised myself, the filter was fairly easy to put in. Of course, I did have the advantage of having a previous filter installed, so I didn't have to put in the adapter to tap off the existing cold water line. I did add an inline shut off on the flexible plastic supply line, so I could shut off the water without crawling under the sink to make it easy to change filters later. My local hardware store had a brass inline filter with compression fittings for a very inexpensive price. On the whole, I was impressed with the installation kit. the manufacturer included a good supply of good quality water line, all the fittings needed to install, and even put in a roll of Teflon tape! One word of caution, so you don't make the same mistake I did. When you take the plastic off the filters and reinstall them into the unit, be extra careful that the o-ring stays in its groove so you get a good seal. The instructions recommend using some food grade silicone if you find it necessary. They're not kidding. I didn't get one of the O-rings straight, and when I put water to the system it leaked. It was my mistake, not the mistake of the unit. I shut the water back off and fixed the o-ring into the right position, then everything was fine. I will be getting a tube of that food-grade silicone when it is time to replace the filters. Other than that, I have absolutely no complaints with this filter. The water is clean and tastes good again - no more buying bottles of water for us!
