Rust Stain Prevention

We install a rust prevention injection system that prevents rust stain on or around the house. The system includes a 30 gallon tank, injection pump, pump start relay, and UNRUST powder that mixes with water fill the 30 gallon tank. The tank typically needs refilled every couple of months. Most systems require 12 cups of UNRUST powder mixed with water to refill a 30 gallon tank. 12 cups of UNRUST powder come in a 1 gallon container and costs $100.

Please note that there are 2 water conditions that will prevent the rust prevention system from working properly. While these situations are rare, they do occur.

  • The irrigation water is oxidized before the injection point.
  • The well water has iron bacteria in it.
