Conventional RO Systems
Conventional RO systems may provide high quality water. 
However, cartridges and membranes are difficult to replace 
because they are installed in housings and must be removed. 
This procedure includes the need to shut off and drain down 
the system, open the housings with a wrench, remove 
catridges, empty water from the sumps, clean the filter and 
membrane housings, replace cartridges, re-pressurize, and 
check for leaks. 
VS.
• Hinge bracket for easy handling.
• Automatic shut off when cartridges are removed
with a simple, 1/4 turn.
• No need to disconnect tubing when replacing membranes.
• Integrated check valves between cartridges and

membrane prevent back-flow.
Because conventional systems are difficult to service, routine 
maintenance may be delayed. Therefore, consumers may not 
get the quality water they desire, unless a qualified dealer is 
called to service their system.
• Cartridges have double o-rings so they will not leak.
• Quick connect fittings for easy installation.
