The iSpring WGB12B is a 1-stage whole house water filtration system designed to provide clean, filtered water throughout your home. This system effectively reduces up to 99% of chlorine, as well as sediments, rust, pesticides, herbicides, industrial solvents, VOCs, and various other contaminants from your water supply. It is particularly effective for city water with low sediment levels. The system features a 20" x 4.5" carbon block filter made from high-quality coconut shell carbon, ensuring maximum filtration efficiency and extended filter life. It is tested by an independent third-party to meet NSF/ANSI standards.
Please note: This system does not reduce Total Dissolved Solids (TDS) and retains healthy minerals in your water. For TDS removal, consider an iSpring Reverse Osmosis (RO) system.

5. Instalacija
5.1. Priprema
- Carefully read the entire user manual before installation.
- Ensure all parts are included and you have all necessary tools.
- Determine the appropriate inlet/outlet port size for your plumbing (WGB12B uses 1" female NPT threads).
- Plan your installation location, ensuring sufficient space for filter changes and maintenance.
- It is recommended to install a water router bypass to ease future filter replacement and system maintenance.
- Turn off the main water supply to your home and open the nearest faucet to drain water from the pipes and release pressure.
Applying Plumber's Tape:
Plumber's tape (thread seal tape) is crucial for preventing leaks at threaded connections. Ensure threads are clean and free from debris. Test the fitting size before applying tape.
Video 1: Step-by-step guide on how to correctly apply plumber's tape to fittings.
- Apply 6-8 wraps of tape in a clockwise direction around the threads.
- Press the tape down firmly into the threads.
- Add another 6-8 wraps and press down again. For 1-inch fittings, 12-15 wraps are recommended.
- Ensure the tape edges are neat and will not come loose.
5.2. System Assembly and Connection
Follow these steps to assemble and connect your filtration system:
- Raspakiraj filtere: Remove the plastic wrapping from the carbon block filter cartridge.
- Umetni filter: Carefully insert the filter into the housing. Ensure the filter's center hole slips over the center knob at the bottom of the housing.
- Nosač za montažu: Mount the system's bracket securely on the wall.
- Spojni fitinzi: Apply plumber's tape to the inlet and outlet fittings and carefully insert them into the corresponding ports on the filter head. Tighten with a wrench, but do not overtighten to avoid cracks.
- Priložite kućište: Screw the filter housing onto the filter head. Hand-tighten first, then use the included housing wrench for another quarter to half turn. Do not overtighten.
- Connect to Pipeline: Connect the system to your main water pipeline. Ensure the "Water Flow" direction arrow on the machine head matches the direction of water flow within your pipeline.

6. Operacija
- Obnova vodosnabdijevanja: Slowly turn on the main water supply to your home.
- Provjerite ima li curenja: Carefully inspect all connections for any signs of leaks. Tighten any leaking connections as needed, but do not overtighten.
- Sistem za ispiranje: Open a nearby cold water faucet and let the water run for approximately 10 minutes. This flushes out any air, carbon fines, and debris from the system. The water may appear cloudy or discolored initially; this is normal. Continue flushing until the water runs clear.
- Potvrdite rad: Ensure the system is working properly and there are no leaks.
7. Održavanje
7.1. Zamjena filtera
The carbon block filter cartridge should be replaced according to the manufacturer's suggested schedule or as needed, typically every 6 months or after 15,000 gallons, depending on water quality and usage.

Figure 6: Various iSpring filter cartridges and their functions.
- Isključite vodu: Shut off the main water supply to the system.
- Pritisak otpuštanja: Press the red pressure relief button on top of the filter head to release any trapped pressure.
- Odvrnite kućište: Use the housing wrench to unscrew the filter housing counter-clockwise. Place a bucket underneath to catch any residual water.
- Uklonite stari filter: Remove and properly dispose of the expired filter cartridge.
- Čisto stanovanje: Clean the inside of the filter housing and the housing cap with lukewarm water mixed with two tablespoons of household bleach, using a sponge or soft cloth. Rinse thoroughly.
- Pregledajte O-prstenove: Inspect the housing O-rings for any cracks or wear. Replace if necessary. Apply a thin layer of food-grade silicone lubricant to the O-rings to ensure a proper seal.
- Umetni novi filter: Unwrap and insert the new carbon block filter cartridge into the housing, ensuring it seats correctly over the center knob.
- Reinstall Housing: Screw the housing back onto the filter head. Hand-tighten first, then use the wrench for another quarter to half turn. Do not overtighten.
- Restore Water & Flush: Slowly turn on the main water supply and check for leaks. Flush the system by running a nearby cold water faucet for 10 minutes until the water is clear.
8. Otkrivanje problema
| Problem | Mogući uzrok | Rješenje |
|---|---|---|
| Curenje vode | Loose connections, damaged O-rings, incorrect plumber's tape application. | Tighten connections, replace O-rings, reapply plumber's tape correctly. Ensure housings are not overtightened. |
| Nizak pritisak vode | Clogged filter cartridge, air in the system, undersized plumbing. | Replace filter cartridge, flush system to remove air, consult a plumber for plumbing issues. |
| Cloudy/Discolored Water | New filter carbon fines, trapped air, excessive sediment. | Flush the system for a longer period (up to 20-30 minutes). If problem persists, check water source or filter. |
