Residential Filtration System

Residential Filtration System

Feed water first enters the pre-filter which reduces chlorine and suspended particles. The filtered water then flows through the automatic shut-off valve and enters the reverse osmosis membrane where the permeate (pure water) passes through and the waste water goes to the drain.



The highly purified water produced by the membrane flows, via the other side of the automatic shut-off valve, through a Doulton ceramic cartridge (certified by the removal of microbiological contaminants such as E. coli and Salmonella). Thereafter, the water passes slowly through pH boosting/alkalizing media and a post-carbon polishing filter before entering the pressurized storage tank.

Water drawn from the faucet is pure, re-mineralized, highly alkaline and bears anti-oxidant properties evidenced by a negative Oxidation-Reduction Potential (ORP) typically in the -100 to -200 range.

This schedule is designed for the average potable water supply and should be followed to ensure the proper functioning of your drinking water system.

Carbon Pre-Filter – Replace every 12 months

Membrane – Test annually and replace when the membrane no longer consistently removes at least 75% of the Total Dissolved Solids.

Ceramic Filter – Handled properly this cartridge should never need to be replaced. It can be cleaned repeatedly as required.

High pH Cartridge – Test pH regularly and replace when readings are consistently below 9.0. Depending on family size and use, this cartridge is expected to last from 1-3 years.

Carbon Post Filter – Replace every 12 to 24 months (or if unpleasant or stale taste occurs)

Storage Tank – Repressurize to 7 psi annually (or as needed).
