Review on ERP 500 PERMEATE MOUNTING INCLUDING by Latarsha Spencer

But after reading the installation instructions for the Watts permeate pump for our Kwik-Change reverse osmosis system (available online), I realized You will need a tank line tee and tap to the permeate clean water outlet on the pump after disconnecting and plugging in the blue line elbow above the green filter (membrane cartridge). Now it works great. The ratio of 1 to 9 has dropped to 1 to 5, resulting in a nearly 50% reduction in wastewater. This equates to a monthly reduction of 300 gallons. Yes, it's easy to install once you know what you're doing. But don't assume anything like me, because you will be wrong.
