A Practical Guide to Installing Your Water Purifier

A Practical Guide to Installing Your Water Purifier

Installing a water purifier doesn’t require professional expertise for most models. Follow this step-by-step guide to
ensure a seamless setup, whether you’re using an under-sink system or a countertop unit.

Pre-Installation Preparations

  • Gather Tools: Wrench, plumber’s tape, screwdriver, bucket, and pipe cutter (for under-sink models).
  • Shut Off Water Supply: Turn off the cold water valve under the sink or at the main line. Open the faucet to drain residual water and relieve pressure.
  • Read the Manual: Familiarize yourself with the unit’s components and specific instructions, as steps vary by model.

Under-Sink Purifier Installation

  1. Mount the Unit: Secure the main housing to the cabinet wall using the provided brackets and screws. Ensure it’s level and stable.
  2. Connect the Inlet Pipe:
    • Attach a saddle valve to the cold water line using a wrench. Tighten with plumber’s tape to prevent leaks.
    • Run the feed tube from the saddle valve to the purifier’s inlet port, ensuring a snug fit.
  3. Install Filters: Insert pre-assembled filter cartridges into their housings. Some models use quick-connect fittings; others require twisting until they click.
  4. Attach the Outlet Tube: Connect the purified water line to a dedicated faucet (included with most kits) or an adapter on the existing faucet.
  5. Flush the System: Turn on the water supply and let the purifier run for 10–15 minutes to flush out carbon dust and air bubbles. Discard the initial water.
  6. Check for Leaks: Inspect all connections with a paper towel. Tighten gently if needed, avoiding over-tightening that could crack fittings.

Countertop or Faucet-Mounted Models

  • Countertop Units: Place the purifier on a stable surface. Attach the inlet tube to the faucet using the provided adapter, ensuring a secure seal.
    The outlet spout should align with a water container for easy dispensing.
  • Faucet-Mounted Units: Screw the purifier directly onto the faucet spout, switching between “purified” and “regular” modes via a toggle valve.
  • No tools are required—simply hand-tighten the adapter.

Post-Installation Tips

  • Label Filter Installation Dates: Use a marker to note the date on filter housings for easy replacement tracking.
  • Test Water Quality: Use a TDS meter to compare pre- and post-purification readings. A significant drop (e.g., from 300 to 20 ppm) indicates effective filtration.
  • Sanitize for Well Water: If using well water, run a food-grade disinfectant solution through the system as per the manual to eliminate potential bacterial residues.
