• 8 oz of UNRUST Stain Preventer is the same as 1 gallon of most formulas of "Other Brands" liquid chemical.

• If you normally use 4 gallons of liquid chemical in your Rust Prevention System tank use 4 cups of UNRUST Stain Preventer.

• Add it to your chemical injection tank, and fill with water to mix. 

• If you are starting up a new system we recommend that you send us a water sample for a free Water Test to find out your Iron and Hardness levels and we will help you choose the best system to fit your need

• If you already have a system and you need to know your Iron and Hardness levels you can also send us a water sample for a free Water Test.

• If you don't want to wait you can find an inexpensive test kit at your local hardware store or do the following:

Here is an easy way to get the right amount of chemical needed for your system.

1. Place a piece of white PVC pipe, masked with tape, in a zone that is the worst for staining.

   2.   Run that zone with the PVC pipe in a wetting area.

   3.   Let the PVC pipe dry, pull back the tape and check for any signs of staining.

   4.   If staining is present, add one more cup of UNRUST Stain Preventer.

   5.   Repeat steps 1,2,and 3, adding UNRUST Stain Preventer, until no stains are present.  

   • If the water has hardness greater than 5 grains per gallon of calcium carbonate, you will need to add 1 cup of UNRUST Stain Preventer, for every 5 grains of hardness. If you do not know what the hardness of your water is, you can get a inexpensive test kit at your local hardware store.  
   • On average you will need 1 cup of UNRUST Stain Preventer for every 1 ppm of Iron and 1 more cup for every 5 grains of hardness.
   • Example;

             You have; 
                                2 ppm of Iron                 =  2 cups of UNRUST Stain Preventer
                              10 grains of hardness      =  2 cups of UNRUST Stain Preventer

   Total needed     =  4 cups of UNRUST Stain Preventer
