Brine Tank and Salt Bridge Repair in St. Charles, MO
A salt bridge, a crust of salt that forms in the brine tank, can prevent your water softener from regenerating properly. This leads to hard water throughout your home. Our team can effectively break up and remove salt bridges, clean the brine tank, and advise on best practices to prevent future occurrences. We also repair leaks or damage to the brine tank itself, frequent in older systems.

Injector and Brine Line Cleaning in St. Charles, MO
The injector, sometimes called a venturi, creates suction to draw brine into the resin tank. Sediment and salt residue clog its tiny ports. When it clogs, the brine tank fills with water instead of emptying. We clean or replace the injector and screen and check the brine line for leaks.
