Introduction
This manual provides instructions for the installation, operation, and maintenance of the American Plumber DW-2000-RB / UC-1RB Replacement Filter. This filter is designed to reduce chlorine taste and odor, sediment, and turbidity in your drinking water.
It is compatible with American Plumber DW-1200-U and DW-2000-U undersink Water Filter Housings, and serves as a replacement for Culligan UC-1R, UC-1RB, UC-2R, and UC-3R water filters.
Product Overview
The image displays the American Plumber DW-2000-RB Replacement Water Filter Cartridge alongside its retail packaging. The cartridge is cylindrical, primarily silver-colored with a blue and red label. The label indicates it is a "Replacement Filter Cartridge DW-2000-RB" for "DW-1200-U & DW-2000-U Under-Counter Drinking Water Filter Systems." It highlights that it "Reduces: Chlorine Taste & Odor, Bad Taste & Odor, Sediment." An arrow on the cartridge indicates the correct installation direction ("Install with this arrow pointing straight up"). The packaging box reiterates this information and includes contact details for American Plumber.
Setup and Installation
Before You Begin:
- Ensure the water supply to the filter housing is turned off.
- Have a bucket or towel ready to catch any residual water.
- Locate your existing filter housing, typically found under the sink.
Installation Steps:
- Remove Old Filter: Carefully unscrew the filter housing sump. Remove the old filter cartridge and discard it properly.
- Clean Housing: Clean the inside of the filter housing sump with warm, soapy water. Rinse thoroughly.
- Lubricate O-Rings: Inspect the O-rings on the filter housing. If they appear dry or damaged, replace them. Apply a thin coat of food-grade silicone grease to the O-rings to ensure a good seal.
- Insert New Filter: Unwrap the new American Plumber DW-2000-RB filter cartridge. Insert the new cartridge into the filter housing sump, ensuring the arrow on the cartridge points straight up towards the housing head.
- Reassemble Housing: Carefully screw the filter housing sump back onto the housing head. Hand-tighten only; do not overtighten.
- Restore Water Supply: Slowly turn on the water supply to the filter housing. Check for any leaks.
- Flush Filter: Allow water to run through the filter for several minutes (e.g., 5-10 minutes) to flush out any carbon fines and air. The water may appear cloudy initially; this is normal and will clear.
- Record Date: Write the installation date and the next recommended filter change date on the label provided on the filter cartridge or in a convenient location.
Operation
The American Plumber DW-2000-RB filter operates passively once installed. Water flows through the filter cartridge, where contaminants such as chlorine, sediment, and turbidity are reduced. No user interaction is required during normal operation.
Maintenance
Regular replacement of the filter cartridge is essential to maintain optimal water quality and flow rate.
- Filter Replacement Schedule: The filter needs to be replaced every 12 months or after filtering 2,000 gallons of water, whichever comes first. Actual replacement frequency may vary depending on local water quality and usage.
- Signs of a Clogged Filter: Reduced water flow, noticeable changes in taste or odor, or visible sediment in the filtered water indicate that the filter may need to be replaced sooner than the recommended schedule.
- Replacement Procedure: Follow the "Setup and Installation" steps outlined above to replace the old filter cartridge with a new one.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Reduced Water Flow | Clogged filter cartridge. | Replace the filter cartridge. |
| Unpleasant Taste/Odor | Filter cartridge has reached its capacity or is expired. | Replace the filter cartridge. |
| Water Leaks from Housing | Improperly seated O-rings, damaged O-rings, or overtightened housing. | Turn off water, check O-rings for proper seating and damage. Lubricate O-rings. Ensure housing is hand-tightened only. |
| Cloudy Water After Installation | Air trapped in the system or carbon fines from new filter. | Flush the filter by running water for 5-10 minutes until clear. |
