Olympia Water Systems Reverse Osmosis Water Filtration System is designed and tested to provide clean, high-quality drinking water at your home or business. The OROS-50-PMT includes a permeate pump that operates using built-up pressure from RO membrane wastewater (does not require electricity). The permeate pump increases RO system efficiency by filling the tank faster than a standard system, which makes it ideal for low-pressure homes and well water (30-50 psi).

This system does not include a separate Automatic Shut-off Valve, the Permeate Pump will automatically shut-off the RO system when the storage tank is full. However, without a separate Automatic Shut-off Valve installed, you may notice “TDS Creep”, which is a slight increase in TDS (total dissolved solids) readings under normal household operation. Infrequent system usage will increase the amount of “TDS Creep”. If you notice a large increase in TDS in your filtered water, you may want to consider adding an Automatic Shut-off Valve to the system. Please see our Technical Documents section on our FAQ page for instructions on adding a separate Automatic Shut-off Valve to this RO system.
