Introduction

Thank you for buying the Zero Waste Retrofit Kit.  This kit is designed 

to retrofit existing reverse osmosis systems and save water from 

being wasted. 

How it works:

This conversion kit works by using the booster pump to increase 

the pressure throughout the system so that the brine water (which is 

usually wasted) can be recycled back into the hot water line.  Here is 

what each component does:

• 

Booster Pump: Boosts the pressure throughout the system.

• 

 Solenoid: Shuts off the water to the unit when the tank is full.

• 

 Pressure Switch: Turns off the pump and closes the solenoid 

when the tank is full.

• 

 Check Valve: A one-way valve that allows the brine (waste) 

water to get pushed into the hot water, but not let any hot 

water back in.

• 

 Flow Restrictor:  Controls how much water is returned into 

the hot water line.  See instructions for sizing.

• 

Transformer: Provides power to the electrical components.
