Water Doctors PRO-2000 Under Sink Water Filter System

Water Doctors PRO-2000 Under Sink Quick Change Water Filter System With "-60" Threaded Filters

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 shown below.  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 quick change filter cartridges included.  Simply disconnect the inlet and outlet tubes from the old system and connect them to the new system.  Done!

Once you convert to the standard "Q" series head you will be able to start sanitizing your Water Filter system using the sanitizing cartridge listed below.  You will need 2 to fully sanitize your system.  They are reusable indefinately.

The PRO-2000 under counter water filter system uses John Guest ® quick connectors.
