This is a point-of-entry 58SXT-1.0-FX well water filter system for iron, sulfur, and manganese at 5-6 GPM.
The point-of-entry 58SXT-1.0-FX well water filter system at 5-6 GPM is a whole house system to reduce iron, hydrogen sulfide, manganese, dirt, rust, sediment, metallic taste, rotten-egg odor, and staining before water reaches sinks, tubs, toilets, showers, laundry, plumbing, and appliances.
This system uses Filox media with a Fleck 5800SXT digital backwashing control valve. It oxidizes dissolved metals and automatically backwashes with water to rinse the media bed clean, with no chemicals or salt required.

This system is not a water softener, carbon filter, lead filter, or UV disinfection system. If your water also has hardness, bacteria, low pH, tannins, chlorine, or other dissolved contaminants, additional treatment may be needed based on water testing.
Why Filox media matters
Filox is designed for well water problems involving iron, sulfur odor, and manganese. The media helps oxidize dissolved metals, allowing them to be captured in the media bed, which is then flushed to drain during the automatic backwash cycle.
This makes the 58SXT-1.0-FX a strong option for smaller homes where iron staining, rotten-egg smell, metallic taste, or manganese discoloration is the main water concern.
Why the Fleck 5800SXT valve matters
The Fleck 5800SXT digital control valve automatically manages the system’s backwash cycle. It helps clean and reclassify the Filox media bed, reduce manual maintenance, and keep the system operating more consistently than cartridge-only iron filtration.

Install difficulty: Moderate to advanced
This is a main-line point-of-entry well water system that requires plumbing into the home’s water line, routing a drain line for backwash discharge, connecting power to the control valve, and programming the Fleck 5800SXT. A plumber or water treatment installer is recommended for most homeowners.
Installation: 58SXT-1.0-FX Well Water Filter System
- Install the system on the main water line after the pressure tank and before water branches throughout the home.
- Choose a level location with access to power, a suitable drain, and enough clearance for the 58.25-inch overall system height.
- Confirm the drain route can handle the required 6 GPM backwash flow.
- Shut off water and depressurize the plumbing system.
- Position the Structural Polyglass tank securely on a level surface.
- Connect inlet and outlet plumbing to the stainless steel bypass with 1-inch FNPT ports.
- Route the drain line according to the assembly instructions and local plumbing requirements.
- Plug in and program the Fleck 5800SXT control valve.
- Slowly pressurize the system and check the bypass, valve, fittings, and drain line for leaks.
- Run the startup and backwash steps in the well water system assembly instructions before normal service.
Maintenance Schedule
- Backwash schedule: program according to water quality and household usage
- Monthly: confirm the system is cycling normally and check the valve, bypass, fittings, and drain line for leaks
- Every 6 to 12 months: review valve settings and adjust backwash frequency if staining, odor, metallic taste, or flow changes
- Media replacement: replace Filox media every 5 to 10 years in most residential applications
- As needed: service the valve or adjust programming if staining, sulfur odor, manganese discoloration, or sediment returns
Replacement Triggers
Service, inspect, or adjust the system if you notice:
- Iron staining returning on sinks, tubs, or toilets
- Rotten-egg odor returning
- Black manganese staining returning
- Metallic taste returning
- Dirt, rust, or sediment downstream
- Flow rate dropping and not recovering after backwash
- Backwash cycle not running as programmed
- Water running to drain outside the expected cycle
- Leaks around the valve, bypass, fittings, or drain line
