What to do if my water filtration system leaks after installation?

If your water filtration system leaks after installation, stop the water and have the system checked by Summers Plumbing Heating & Cooling right away. Most new leaks come from a loose push-to-connect fitting, a twisted O-ring, or an over-tightened plastic thread that seeps once the system is pressurized. After the first pressure cycle, a slightly mis-seated RO tube can start a slow drip even if it looked dry at startup. Our licensed plumbers serve the Downs area, and our emergency phone line is available 24/7.

Until help arrives, these steps can limit damage:

• Close the feed valve to the filter; for RO, also close the tank valve.
• Turn off any booster pump or unplug the unit.
• Open the filtered-water faucet to relieve pressure.
• Dry the area and place a bowl or towel under the suspect joint; avoid using the system.

If water is near electrical equipment or materials are swelling, treat it as an emergency and call immediately. <br/> Updated: 2026-06-11 <br/> Need help in Downs, IL? Call (309) 317-4215 or book online.
