For the first time in three years our kitchen sink actually works and
consists of all the same material pipes. I am so happy. In reality
it took us only about 2 hours to cut and fit everything which makes me
so mad considering we had a leaky sink and bucket under there for
three years.

What is the osmosis membrane made of?
It is a reverse osmosis water filtration system (e:paul,42425) and I love it.
I have been in my house about 3 years as well. I have had projects take less time and when I was done I thought the same exact thing. Are those water filters under there? Do they work well?
