E Coli Bacteria & Well water 3-stage 20"x 4.5" Whole House Water System with 12 GPM UV
Improve the water quality throughout your home, cottage or light-commercial property with the Max Water 3-Stage Big Blue Whole House Water Filtration System with 12 GPM ultraviolet water treatment.
This complete water-treatment package combines two sediment filtration stages, one granular activated carbon stage and a UV system to help reduce suspended particles, chlorine, unpleasant taste and odour while providing an additional ultraviolet treatment stage for properly pre-filtered water.
The oversized 20" x 4.5" Big Blue housings provide increased dirt-holding capacity, longer service intervals and better flow potential than standard slim-line filtration systems. The 1" female NPT ports are suitable for many residential and light-commercial plumbing installations.
Three Stages of Whole House Filtration
- 5-Micron Polypropylene Sediment Filter
Part No. 104112 . Captures larger suspended particles such as sand, rust, dirt and silt while helping protect the finer second-stage cartridge. - 1-Micron Polypropylene Sediment Filter
Part No. 104111 . Provides finer sediment filtration to reduce smaller suspended particles and improve water clarity before carbon and UV treatment. - Coconut-Shell Granular Activated Carbon Filter
Part No. 104113 . Reduces chlorine, unpleasant taste, odour and selected organic compounds while helping improve the taste and smell of the water.
Ultraviolet Water Treatment System
The included UV system provides an additional water-treatment stage after sediment and carbon filtration. Ultraviolet light is designed to treat clear, properly pre-filtered water without adding chemicals or changing the water's taste.
- Included UV system: 12 GPM UV system, Part No. 105083 .
- Optional upgrade: 24 GPM UV system, Part No. 105086 , may be selected during checkout when available.
- UV performance depends on water clarity, UV transmittance, flow rate, lamp condition and proper installation.
- Water containing iron, manganese, sulfur, tannins, hardness, turbidity or other interfering contaminants may require additional pre-treatment.
Dual Pressure Gauges
Two vertical hydraulic pressure gauges help monitor the incoming water pressure and the pressure inside the filtration system. Comparing the gauge readings can help identify increasing pressure loss across the filter cartridges.
A growing difference between the inlet and outlet pressure may indicate that one or more cartridges are becoming clogged with sediment or that the filter media has reached the end of its useful service life.

Installation and Maintenance Information
- Install the filtration system on the main cold-water supply line, after the pressure tank when applicable and before the water heater.
- Install the UV system after the filtration stages so that sediment and turbidity are reduced before ultraviolet treatment.
- Confirm the directional flow markings on both the filtration and UV components before connecting the plumbing.
- Do not exceed the rated flow capacity of the installed UV system.
- Support the filtration assembly securely using the supplied steel bracket and suitable hardware for the wall structure.
- Leave sufficient clearance beneath the housings for cartridge replacement and routine maintenance.
- Use suitable thread sealant or PTFE tape on NPT connections. Do not overtighten plastic ports or fittings.
- Shut off the incoming water supply and release system pressure before opening any filter housing.
- Lubricate O-rings only with food-grade silicone lubricant. Do not use petroleum-based lubricants.
- Flush new sediment and carbon cartridges thoroughly before placing the system into normal service.
- Replace the UV lamp according to the manufacturer's recommended schedule and clean or replace the quartz sleeve as required.
Frequently Asked Questions
Q. Is this system suitable for well water?
A. It can be used as part of a properly designed well-water treatment system. The water should first be professionally tested for iron, manganese, sulfur, hardness, tannins, bacteria and other contaminants. Additional treatment may be required before the sediment, carbon and UV stages.
Q. Does the UV system remove sediment, chemicals or hardness?
A. No. UV treatment does not physically remove sediment, chlorine, chemicals, dissolved minerals or hardness. The sediment and carbon cartridges provide the physical and chemical filtration stages, while the UV system provides ultraviolet treatment for clear, pre-filtered water.
Q. Does this system reduce TDS?
A. No. Sediment, carbon and UV treatment do not substantially reduce TDS = Total Dissolved Solids. Reverse osmosis or another specialized process is required when TDS reduction is needed.
Q. How often should the filters be replaced?
A. Replacement frequency depends on water quality and usage. Sediment cartridges are commonly replaced approximately every six months, but heavily contaminated water may require more frequent replacement. Replace the carbon filter when its service capacity is reached or when chlorine, taste or odour returns.
Q. What do the two pressure gauges indicate?
A. The gauges allow you to compare pressure before and after filtration. An increasing pressure difference may indicate that the cartridges are becoming clogged and should be inspected or replaced.
Q. Can the filtration system flow at 40 GPM with the 12 GPM UV installed?
A. No. Although the filter housings may support higher flow under suitable conditions, the complete treatment system must not exceed the rated flow of the installed UV unit. With the included UV model, the maximum treatment flow is up to 12 GPM under suitable operating conditions.
