About this product

Certified High-Volume 4-Stage Reverse Osmosis Water Purifier Provides 50 GPD of RO Treated Water. Optional Germicidal Ultraviolet Available.

The PT-504 fits under most sinks and provides clean, great-tasting water. Reverse Osmosis filtration purifies water by taking out the totally dissolved solids (TDS) which contaminate water. Although city water treatment removes the dirt and debris and adds chlorine to prevent the spread of diseases, it does not remove the dissolved solids from the water. And, with the increasing pollution of our surface and groundwater with contaminants, such as lead, mercury, and chromium-6, as well as the naturally occurring harmful contaminants such as arsenic, fluorides, and sulfides found in some areas of the country, it is more important than ever to have a way to remove these contaminants at the point of use.

4 Stages of RO Purification in the PT-504 PureWaterMachine RO System

The PureWaterMachine PT-504 Reverse Osmosis Drinking Water System comes complete, ready to install with instructions. The 4-stages are pre-assembled and tested.

  • Stage 1 - Sediment Filter, 5-micron poly-spun cartridge - The 5-micron poly-spun filter takes out suspended solids such as dirt, rust, sand, and pipe scale.
  • Stage 2 - Activated Carbon Block Filter, 5-micron - Activated carbon block filter removes chlorine, bad tastes, and odors.
  • Stage 3 - Reverse Osmosis Membrane, 50 GPD - The heart of the Vertex PureWaterMachine is the reverse osmosis membrane. RO technology removes on average 95% of the dissolved solids in your water. Dissolved solids are not removed by municipal water treatment. This is why the Vertex PureWaterMachine RO System is an important safety factor for the water you drink and use in your cooking. City water pressure is used in the reverse osmosis membrane to force the water molecules through the membrane, but the larger contaminant molecules are kept behind and flushed to the sewer. The clean water goes into the storage tank and is held there ready for use. An auto-valve turns off the water when the tank is full. The tank is pressurized with a bladder which pushes the water out through the final filter.
  • Stage 4 - Granular Activated Carbon post-filter - When the faucet is opened, clean water from the storage tank flows through the final polishing filter of activated carbon and into the faucet for your use. This special faucet is installed on your sink to dispense safe, great-tasting drinking water which is especially good for coffee, tea, and drinks.
  • OPTIONAL STAGE 5 - Germicidal Ultraviolet - UV light kills 99.9% of harmful bacteria in point-of-use filter systems and is FDA approved for disinfecting filtered water. The UV lamp radiates at 253.7 nanometers with a power flux of 40,000 microwatt-seconds per square centimeter. UV energy at 254 nm kills 99.9% of various microorganisms. As the water flows around the lamp (which is encased in a quartz sleeve), it is irradiated by UV light. 9,000 hour lifetime.
    Replace annually.

NOTE - The UV stage is recommended for well water in rural areas, or in towns and villages that have uncertain chlorination. If your water is being supplied from a well or spring you should consider Ultraviolet. Or, if you're not sure that your municipality is sufficiently chlorinating the water supply, you may want to consider adding UV as a final stage in your purification process.

Best for

Installation tips

  • Choose a location under the sink with enough space for the RO module + storage tank.
  • Mount the RO faucet in a convenient spot on the sink or countertop (air-gap not required unless local code mandates it).
  • Shut off cold-water supply; install the feed-water adapter and connect the RO tubing.
  • Connect the drain saddle to the sink drain line—ensure the hole aligns properly to avoid noise or slow draining.
  • Install filters and membrane per the labeled positions in the RO module.
  • Turn on water and flush the system for 2–3 minutes, then allow the storage tank to fill completely.
  • For best performance, fill the tank once, then drain it fully to activate the membrane.
  • Replace pre-filters every 6–12 months and the RO membrane every 2–3 years depending on water quality.

NOTE: Warranty on the system is void unless installed by a licensed plumber.

NOTE: Do not use with water that is microbiologically unsafe, or of unknown quality, without adequate disinfection before or after the system.

Frequently asked questions

How pure is the water produced by the PT-504?
Reverse osmosis removes a wide range of contaminants including dissolved solids (TDS), chlorine, sediment, chemicals, and odors, producing fresh, clean drinking water.

How often do the filters need to be replaced?

  • Sediment & carbon filters: every 6–12 months
  • RO membrane: every 24–36 months
  • Post carbon filter: every 12 months

Replacement timing may vary depending on water quality and usage.
