Installing the Corrosion Coupons (Optional)
Most systems includes the provision for conducting Corrosion Coupon Testing. To conduct this test you
will first need to request coupons from EcoWater CHC.
These coupons will be installed for no less than 60 days before they are removed and weighed. The
coupons can be installed up to 120 days before removal. This installation requires the use of
Nitrile Gloves to insure no contamination of the coupons occur. Place the coupon envelopes in a
location whereas they can be used as the coupons are removed.
To install the Corrosion Coupons follow these steps:
1. Acquire the coupons, you will receive one Galvanized coupon, one Stainless Steel or mild Steel
coupon and one Copper coupon (Normal Configuration, other coupons are available if requested).
2. The coupons are placed so that the Copper coupon will be first coupon that the water will come in
contact with, the Stainless Steel coupon will then be placed next and followed by the Galvanized
coupon.
3. Turn off the two isolation valves at the rack to stop all water flow.
4. Loosen the nut securing the coupon holder.
5. Remove the coupon holder rod from the coupon rack.
6. Remove the coupon installation screw from the coupon holder.
7. Place a coupon over the holder and secure with the installation screw.
8. Place the holder back into the rack so that the coupon is extended into the water flow tube in a
vertical position. Do not place the orientation of the coupon in a horizontal position, if horizontal,
the coupon can act like a shelf and support debris that maybe detrimental to your test results.
9. Secure the holder into place by tightening the holder nut.
10. Open the rack's isolation valves.
11. Verify that the flow across the coupons is between five and eight GPM as shown on the flow
meter.
12. Mark the coupon envelopes with the date of installation and place in a secure location for use upon
the completion of the testing.
