Greg - although a self piercing needle valve is an option, there are better choices.

Assuming you have 1/2 inch copper pipes in your houdse, are you comfortable working with compression fittings or sweating some fittings in? That's probably the best (but not the easieest for all people) option.

Next, think about tapping into a 3/8" line under a sink with a reducing tee teamed up with a microvalve. another good choice is a "undersink adapter" or a hose bib adapter.

If youd like, PM me your email and I'll email you a pdf that will walk you through some of the things you should think about re setting up the feed water and drain water lines.
