My Ro/di is being a PITA. The brass part that holds on to the water faucet wont stay, it keeps coming off. My water pressure has not gone up or down. what do i do?
Here are the pix of how it is installed. Don't forget to shut off the water to the pipe your working with, and run the tap to drain the line, and still have something to catch what ever water may still be in the pipe.
