The Fleck 58SXT-1.0-MZ 6 GPM Micro-Z sediment well water filter is a point-of-entry whole house water system designed to reduce sediment and particulates throughout the home using Micro Z filtration media and an automatic Fleck 5800SXT backwashing control valve. It is a main-line filtration system for homeowners who want a low-maintenance alternative to frequent cartridge changes when sediment, turbidity, or fine particles are affecting water clarity, flow, fixtures, appliances, or downstream filtration.
Model number: 58SXT-1.0-MZ
Media type: Micro Z filtration media
Control valve: Fleck 5800SXT automatic backwashing control valve
System type: Backwashing whole house sediment and particulate filtration system
What is the 58SXT-1.0-MZ 6 GPM Micro-Z Sediment Well Water Filter Used For?
- Whole house sediment reduction
- Reducing suspended particles that can affect water clarity
- Protecting downstream filters, UV systems, softeners, RO feed lines, appliances, and plumbing fixtures
- Helping reduce cartridge changes when sediment load makes standard cartridge filters plug too quickly
- Well water or other incoming water supplies where sediment and turbidity are common concerns
What it helps reduce
- Dirt
- Sand
- Silt
- Rust particles
- Suspended sediment and particulate
This system is not designed for chlorine taste and odor, water softening, lead reduction, or microbial disinfection. If those are water concerns, additional treatment such as carbon filtration, softening, lead reduction filtration, or UV disinfection may be needed.
Why is Micro Z Media used?
Micro Z is used as a backwashing media filter for sediment and particulate control. Water flows through the media bed during normal service, and trapped particles are flushed to drain during the backwash cycle. This makes it a useful option when a home needs whole house sediment reduction, but the homeowner wants to avoid replacing cartridge filters too frequently.
Why the Fleck 5800SXT valve matters
The Fleck 5800SXT control valve automatically manages the backwash and rinse cycles. In practical terms, that means the system can clean and reclassify the media bed on a programmed schedule, helping maintain more consistent flow and performance over time.
Control valve benefits
- Digital programming
- Automatic backwash scheduling
- Reliable cycle control for media cleaning
- Easier adjustments if water conditions or household usage change
Compatibility checks before ordering
Before buying, confirm:
- Your main concern is sediment, turbidity, or suspended particulate
- You have a drain location for backwash discharge
- You have a nearby electrical outlet for the control valve
- Your plumbing can be adapted to the system’s connection size
- Your home’s peak flow demand matches the system size
- You have enough space for the tank, valve height, and service access
- Your water does not require additional treatment for bacteria, hardness, chlorine, iron, sulfur, or lead unless you plan to add the proper treatment stage
What’s included
- Fleck 5800SXT backwashing control valve
- Structural polyglass mineral tank
- Micro Z filtration media
- Internal distributor/riser assembly
- Whole house system assembly instructions
Install difficulty: Moderate to advanced
This is a main-line whole house installation that requires plumbing into the home’s water line, providing a drain route for backwash discharge, connecting power for the digital valve, and programming the control valve. A plumber or water treatment installer is recommended unless you are experienced with installing a whole house water system.
Installation: 58SXT-1.0-MZ 6 GPM Micro-Z Sediment Well Water Filter
- Install the system on the main water line after the pressure tank or main shutoff and before water branches throughout the home.
- Choose a location with access to power, a drain, and enough room for service.
- Shut off water and depressurize the plumbing system.
- Position the tank on a level surface with enough overhead clearance for the valve.
- Connect inlet and outlet plumbing with properly supported fittings.
- Route the drain line according to the system instructions and local plumbing requirements.
- Plug in the Fleck 5800SXT valve and program the backwash schedule.
- Slowly pressurize the system and check all fittings for leaks.
- Run the required startup and backwash steps before normal service.
- Recheck for leaks and confirm normal flow after startup.
Maintenance Schedule
- Backwash schedule: set according to water conditions and household usage
- Monthly: confirm the system is cycling normally and check for leaks around the valve and fittings
- Every 6 to 12 months: inspect drain line routing and confirm the valve settings still match water conditions
- As needed: adjust the backwash frequency if sediment load changes or flow begins to decline
- Media replacement: replace when sediment performance declines and backwashing no longer restores normal operation
Replacement Triggers
Service or adjust the system if you notice:
- Sediment returning downstream
- Cloudiness or visible particles after the system
- Flow decline that does not improve after backwashing
- Valve not cycling or not advancing properly
- Water running to drain outside of a programmed cycle
- System alarms, programming loss, or repeated cycle issues
Common Questions: 58SXT-1.0-MZ 6 GPM Micro-Z Sediment Well Water Filter
Q: What does the 58SXT-1.0-MZ Micro Z system do?
A: It is a whole house backwashing filtration system designed to reduce sediment, turbidity, and suspended particulate.
Q: Is this a water softener?
A: No. This system filters sediment and particulate matter. Water softening is used for hardness minerals that cause scale and spotting.
Q: Does this system reduce chlorine taste and odor?
A: No. For chlorine taste and odor, use carbon filtration before or after this system, depending on the treatment design.
Q: Does this system remove bacteria?
A: No. This is not a disinfection system. If microbial protection is needed, UV disinfection is typically installed after proper prefiltration.
Q: Why choose a backwashing sediment system instead of cartridge filters?
A: A backwashing system can be better when the sediment load is high because it automatically flushes trapped particles to drain instead of relying only on frequent cartridge changes.
Q: Do I need a drain for this system?
A: Yes. Backwashing systems require a drain route for discharge during the backwash cycle.
Q: Do I need power for the Fleck 5800SXT valve?
A: Yes. The digital control valve requires an electrical outlet nearby.
Q: How often does the system backwash?
A: Backwash frequency depends on sediment load, water usage, and system programming. The schedule should be set based on your water conditions.
Q: Can this protect a UV system?
A: Yes. Sediment reduction before UV can reduce turbidity and improve UV performance.
Q: Can I install this system myself?
A: Experienced DIY customers may be able to, but most homeowners should use a plumber or water treatment installer because the system requires main-line plumbing, drain routing, and valve programming.
Choose the Fleck 58SXT-1.0-MZ Micro Z system when you need whole house sediment reduction with automatic backwashing, stronger flow support, and fewer cartridge-style maintenance interruptions.
