Connect an Ice Maker to Your House with Leak-Free Fittings. I have two of these saddle valves in my current house I'll be replacing very soon. I've found them to be too fiddly and too prone to leaking at random times. The replacement t-valves are $10 a piece but that's an easy decision to have something not leak. Will just need to shut the water in the house off for the 20 minutes or so it'll take me to install both of these.
