Slowly turn the main water supply valve back on. The faucet you left open will begin to run. Once the water flows smoothly and the air is purged from the line, you can close the faucet. Then, turn the red handles on the tanks back to the 'service' position, parallel to the water flow. Finally, check for any leaks around the filter housing.

Goal: Return the system to normal operation and verify no leaks exist

  • Slowly turning on the water prevents a sudden surge of pressure (water hammer) that could damage the system.

FAQs

How difficult is it to replace a faucet-mounted water filter for a beginner, and how long should I expect it to take?

This project is designed for beginners and is relatively straightforward. Most individuals can complete the filter replacement in about 45 minutes. Having your materials and understanding the steps beforehand will help keep the process quick and smooth.

What's the most critical safety step, and what should I do if I can't find a shut-off valve under my sink?

The most critical step is to shut off the water supply to prevent flooding and messes. If there isn't a dedicated shut-off valve for the sink, you'll need to turn off the main water supply to your entire home. Always keep towels handy to manage any residual water or small drips.

I've installed the new filter, but I'm seeing leaks. What should I troubleshoot?

Immediately turn off the water supply again. Carefully check that the filter cartridge is seated correctly and the housing is tightened snugly, but not overly so. Sometimes, the O-ring might be dislodged or dirty; ensure it's clean and properly aligned before re-tightening.

Do I need any special tools for this water filter replacement project?

For most faucet-mounted water filter replacements, no specialized tools are required, just your hands for twisting the housing. However, it's wise to have towels or a small basin ready for inevitable drips. Some stubborn housings might benefit from a filter wrench, often supplied with the new filter.
