Drinking Water Systems With Filter Elements
& Hollow Fiber Membranes.

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 cartridges, empty water from the sumps, clean the filter and membrane housings, replace cartridges, re-pressurize, and check for leaks. 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.
Kwik-Change RO System
No Sumps! No Mess! No Fuss!
  • 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.
  • Cartridges have double o-rings so they will not leak.
  • Quick connect fittings for easy installation.
