Water Doctors PRO-4000 4 Stage RO Reverse Osmosis System
Water Doctors PRO-4000 4 Stage RO Reverse Osmosis System With "-60" Threaded Filters and "-60" Threaded RO Membrane
Simply replace your Water Doctors -60 filter heads and start using the standard threaded Omnipure "Q" series replacement water filter cartridges at a lower cost than the -60 threaded filter cartridges.
Only the filter heads will need replaced. Choose either the valved or non-valved heads. The valved head will turn off the water to each filter as the cartridge is removed. If you wish an even easier way to upgrade order the full replacement system below which has the standad threaded Omnipure "Q" series heads and replacement filters and RO membrane included. Simply disconnect the inlet and outlet tubes from the old system and connect them to the new system. Done!
HMI-15, 36,50 Reverse Osmosis Membrane
Choose any of the 3 RO Reverse Osmosis Membranes listed below based on your preference. 15, 36 or 50 GPD (gallons per day) Any of the 3 will work. The larger the GPD rating the faster the system will produce water and store it in the tank ready for use.
Once you convert to the standard "Q" series head you will be able to start sanitizing your RO system using the sanitizing cartridge listed below. You will need 4 to fully sanitize your system. They are reusable indefinately.
The PRO-4000 reverse osmosis system uses John Guest ® quick connectors.
