How to Troubleshoot a Culligan Leak

Meredith Jameson

The Culligan Company manufactures and distributes water products for homes and businesses, including water softeners, drinking water systems, bottle coolers, showerheads, pitchers and whole house water filters. While Culligan products are designed to work well under most circumstances, some problems may arise over time, such as a leak . Troubleshooting this issue may be useful in locating the source of the problem and assisting users in determining a possible fix as well. Contact an authorized Culligan repair technician if the following steps do not resolve the problem.

Drinking Water System

The Culligan Company manufactures a variety of water products for the home.
  1. Gently pull out tubing at the source of the leak and examine the tube for abrasions. Use a small piece of extra fine sandpaper to smooth out the surface of the tube, particularly at the end. Rough tubing may be the cause of the leak.

  2. Examine all tubing connections and tighten if necessary, as loose connections may result in leaks.

  3. Tighten the O-ring assembly, as a loose connection may cause leakage as well. Wipe away excess dirt or debris.

Water Softener

  1. Locate the inlet strainer on the top of the water softener unit. The strainer should be threaded in to the center unit securely until it bottoms out. Improper installation may result in a leak. Remove and re-install the strainer if necessary.

  2. Examine all gaskets, valves and nozzles on the water softener to ensure proper placement and firm connection to the unit. Loose connections or improper positioning may result in leaks. Tighten and correct as necessary.

  3. Wipe away any dirt or residue on the tubing or connections, as this may interfere with proper connections, causing leaks in the system.

Water Filter

  1. Ensure all bypass valves are in the proper position, including the "Cul-Flo-Valv" valve, which should be placed in the "Service" position.

  2. Tighten all connections on the water filter, including nozzles, gaskets and valves. Loose or improper fittings may result in leaks.

  3. Wipe away any dirt or residue on the tubing or connections, as this may interfere with proper connections and result in leaks.
