1. Product Overview
The iSpring WGB32BM is a 3-stage whole house water filtration system designed to provide clean, filtered water throughout your home. This system effectively reduces iron, manganese, chlorine, sediment, rust, herbicides, and industrial solvents, improving water taste and odor. It is particularly effective in reducing iron up to 3.0 ppm and manganese up to 1.0 ppm, utilizing a catalytic media that lasts significantly longer than traditional greensand filters.
The system features a high-capacity polypropylene sediment filter (5 microns), a carbon block filter made from coconut shell carbon for chlorine and odor reduction, and a specialized iron and manganese removal filter. These filters are tested by an independent third-party to meet NSF/ANSI standards and have a capacity of 100,000 gallons, typically lasting a family of four for a full year.
2. Safety Information
Please read and understand all safety warnings and instructions before installing or operating this water filtration system. Failure to follow these instructions could result in property damage, injury, or death.
- Always shut off the main water supply and relieve pressure before performing any installation or maintenance.
- Wear appropriate personal protective equipment, including safety glasses and gloves, during installation and maintenance.
- Do not over-tighten fittings or filter housings, as this can cause cracks and leaks.
- Ensure all connections are secure and leak-free before restoring water pressure.
- This system is designed for cold water applications only (40-100°F / 4-38°C). Do not install on hot water lines.
- Protect the system from freezing temperatures, which can cause damage.
- Keep the system away from direct sunlight and heat sources.
- If you are unsure about any part of the installation or maintenance process, consult a qualified plumber.

4. Installation Guide
The iSpring WGB32BM system is designed for DIY installation. Refer to the detailed steps below and watch the official installation videos for visual guidance.
4.1. Pre-Installation Steps
- Read the Manual: Carefully read the entire user manual to understand the system's technical aspects, limitations, and installation guidelines.
- Gather Tools: Ensure all parts are included in the package and you have all required tools on hand.
- Determine Location: Find a suitable location for the system. It should be installed on the main water supply line to treat all water in your home, after the water meter but before the water heater. Ensure there is enough space for filter replacement.
- Shut Off Water: Bypass or shut off the main water line to your house. Open the nearest faucet to drain water from the pipes and relieve any pressure.
- Prepare Fittings: The system has 1-inch female NPT inlet/outlet threads. If your plumbing is a different size (e.g., 3/4-inch), you will need appropriate converter fittings.
- Apply Plumber's Tape: Apply 6-8 wraps of plumber's tape (thread seal tape) in a clockwise direction to the male threads of all fittings. Press the tape firmly into the threads. Add another 6-8 wraps and press again. This prevents leaks.
4.2. Mounting the System
- Mount the Bracket: Mount the filter system's head unit with the bracket securely to a wall using appropriate screws/hardware. Ensure it is level and can support the weight of the system when full of water.
- Connect to Pipeline: Connect the system to your main water line. Ensure the water flow direction arrow on the machine head matches the direction of water flow within your pipeline.
4.3. Inserting Filter Cartridges
- Unwrap Filters: Unwrap all filter cartridges. The cartridges are individually wrapped to ensure freshness.
- Insert Filters: Insert the filters into their respective housings in the correct order: Sediment (Stage 1), Carbon Block (Stage 2), and Iron/Manganese Removal (Stage 3). Ensure the filter center holes slip over the center knob in the bottom of the housings.
- Check O-rings: Ensure housing O-rings are properly seated to prevent leaks. Apply a thin layer of food-grade silicone lubricant to the O-rings if needed.
- Reinstall Housings: Hand-tighten the housings counter-clockwise onto the housing caps. Use the housing wrench to tighten them another quarter to half a turn. Do not over-tighten.
5. Operating Instructions
5.1. Initial Startup
- Restore Water Supply: Slowly turn on the main water supply to the house.
- Check for Leaks: Carefully inspect all connections and filter housings for any signs of leaks. Tighten any leaking connections as necessary, but do not over-tighten.
- Flush the System: Let water run from a nearby cold water faucet for about 10 minutes until the water is clear and free of air bubbles. This flushes out any carbon fines or loose filter media.
- System Ready: Once the water runs clear, the system is ready for use.
5.2. Normal Operation
The iSpring WGB32BM system operates automatically once installed. It provides filtered water to all cold water outlets in your home. The system is designed to have minimum impact on water flow (up to 15 GPM).
6. Maintenance & Filter Replacement
Regular maintenance and timely filter replacement are crucial for optimal performance and water quality. The filter cartridges have a capacity of 100,000 gallons or approximately one year, depending on water quality and usage.
6.1. Filter Replacement Schedule
- PP Sediment Filter (Stage 1): Replace every 6-12 months.
- CTO Carbon Block Filter (Stage 2): Replace every 12 months.
- Iron & Manganese Removal Filter (Stage 3): Replace every 12 months.
6.2. Filter Replacement Steps
- Shut Off Water: Bypass or shut off the main water line to the system. Open a nearby cold water faucet to relieve pressure.
- Relieve Pressure: Use the pressure release button on top of each filter housing (if applicable) to release any remaining pressure.
- Unscrew Housings: Place a bucket underneath the housings to catch any water. Unscrew the filter housings clockwise using the included housing wrench.
- Remove Old Filters: Remove and dispose of the expired filter cartridges.
- Clean Housings: Clean the inside of the filter housings and housing caps with lukewarm water mixed with two tablespoons of household bleach, using a sponge or soft cloth. Rinse thoroughly.
- Inspect O-rings: Inspect the O-rings for any damage or wear. Replace if necessary. Apply food-grade silicone lubricant to the O-rings to ensure a good seal.
- Insert New Filters: Unwrap and insert the new filter cartridges into their respective housings in the correct order. Ensure they are properly seated over the center knob.
- Reinstall Housings: Hand-tighten the housings counter-clockwise onto the housing caps. Use the housing wrench to tighten them another quarter to half a turn. Do not over-tighten.
- Restore Water & Flush: Slowly turn on the main water supply. Check for leaks. Flush the system by running water from a nearby cold water faucet for 10 minutes until clear.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Water Leakage | Loose fittings or housings, damaged O-rings, insufficient plumber's tape. | Shut off water, relieve pressure. Tighten fittings/housings (do not over-tighten). Inspect and replace O-rings if damaged. Reapply plumber's tape. |
| Low Water Pressure | Clogged filters, air in the system, main water supply partially closed. | Replace filters if they are past their service life. Flush the system to remove air. Ensure main water supply valve is fully open. |
| Poor Water Quality (Taste/Odor) | Expired carbon filter, high levels of contaminants. | Replace carbon block filter. If problem persists, consider a water test to identify specific contaminants and adjust filtration as needed. |
| Iron/Manganese Not Reduced | Expired iron/manganese filter, contaminant levels exceed system capacity. | Replace iron/manganese filter. If levels are consistently high, consider additional pre-treatment or a different system. |
