I purchased a Watts Premier RO-4 from Costco. I'm definitely new to the world of water filtering so was shocked to learn how much wasted water occurs in the reverse osmosis system. I quickly learned that I needed to add a permeate pump, but I have a few questions about installation.
First, the system already has a shut off valve installed. The green input water line goes through the bottom two ports and into the manifold and a blue line coming out of the manifold going to the tank passes through the upper two ports. I believe that I need to remove this shut off valve completely from the system as the permeate pump (and another shut off valve to be discussed later) will fill this role. Is this correct?
Second, there is another blue line coming out of the manifold headed to the faucet, I believe that I end this line because the blue line going to the tank will go through the permeate pump and then tee, one half going to the tank and the other half going to the faucet. Anything wrong with this?
Third, the output water line will go through the other half of the permeate pump and then a drain.
Fourth, I think I need to install another shut off valve. Now, I've read that I need a 90% shut off valve and I hypothesize that the one that is already attached to my system is a 60% shut off valve so I can't reuse it, does this sound right? Also, I'm not exactly how to hook it up. I THINK that the input water line goes through the bottom two ports and that the line going out of the permeate pump to the water tank goes through the upper two ports before it gets to the tee.
Fifth, my psi is about 90-95 psi and the instructions recommend it be around 85 psi. Do I put a pressure regulator/flow restrictor on the input water line before the shut off valve or on the drain line coming out the permeate pump?
Here is the instruction manual for my unit: https://www.wattspremier.com/manuals/199404.pdf
I know this is a lot to ask of someone to help me with, but I thought I would just get all my questions out to start! I just want to hook this up correctly the first time.
Thanks for your help!
