Re: How to fix the under sink valve to filter

From the photo, I'm guessing that valve is threaded into the plastic "T". If so, you just need to remove it, check the thread size, and buy a new one. Those small brass needle valves are very common. Can be found at stores like Lowes, Home depot, or aquarium supply stores.
