1. Introduction
The Watts WR-100 Water Filter Wrench is a specialized tool designed for the removal of water filter housings. It facilitates the loosening of the housing body from the cap, primarily for the purpose of replacing filter cartridges. This wrench is intended for use with residential and RV filter sumps.
Important: This wrench is designed for loosening filter housings only. Do NOT use this wrench to tighten the sump, as this can lead to overtightening and damage.
2. Setup
Before attempting to change a water filter, ensure the following:
- Turn off the water supply to the filter system.
- Relieve any pressure in the system by opening a nearby faucet or using a pressure relief button on the filter housing, if available.
- Have a bucket or towels ready to catch any spilled water during the filter change process.
- Ensure you have the correct replacement filter cartridge.
3. Operating Instructions
Follow these steps to use the Watts WR-100 Water Filter Wrench:
- Position the circular end of the WR-100 wrench over the filter housing sump.
- Slide the wrench down until it achieves a snug fit around the housing, engaging the teeth or ridges on the wrench with those on the housing.
- Apply firm, counter-clockwise pressure to the wrench handle to loosen the filter housing. The housing should begin to unscrew.
- Once loosened, you can typically unscrew the housing by hand.
- Remove the old filter cartridge and proceed with replacing it according to your filter system's specific instructions.

4. Maintenance
The Watts WR-100 Water Filter Wrench requires minimal maintenance:
- After use, wipe the wrench clean with a damp cloth to remove any water or debris.
- Store the wrench in a dry place, away from direct sunlight or extreme temperatures, to prevent material degradation.
- Inspect the wrench periodically for any signs of cracks or damage. If damaged, replace the wrench to ensure safe and effective operation.
5. Troubleshooting
- Wrench does not fit the housing: Ensure the wrench is compatible with your specific filter housing model. The WR-100 is designed for Watts residential/RV housings. Some older or non-Watts housings may have different dimensions.
- Housing is too tight to loosen:
- Verify that the water supply is completely off and pressure has been relieved.
- Apply steady, firm pressure. Avoid sudden jerking motions.
- If the housing is extremely tight, ensure the wrench is fully engaged. In some cases, a second person might be needed to stabilize the filter system while the wrench is turned.
- Wrench slips: Ensure the wrench is properly seated and snug against the housing. The housing and wrench should be dry to maximize grip.
