Overview

The Hydro-Guard HG-6 Hydrant-
Based Flushing System is a 
portable and emergency use device 
designed to flush water lines from 
fire hydrants located anywhere in 
the distribution network. These 
devices require the hydrant to be 
live when programmed for flushing. 
The HG-6 has been engineered and 
manufactured to provide outstanding 
dependability and performance.

1. 

Remove the Hydro-Guard Unit 

from its packaging and inspect 
for possible damage during 
shipping.

2. 

Using the pumper nozzle, flush 

hydrant for several minutes to 
ensure the water flow is free of 
debris (i.e., rocks, etc.)

3. 

Confirm hydrant is turned off.

4. 

Gather 2" NTP connector and 

hydrant wrench.

5.

 If necessary, loosen but do not 

remove the four bolts on the 
side of the Hydrant Flusher 
in order to adjust connection 
height, ensuring the device is 
supporting its own weight. Once 
proper height is determined, 
tighten the four height 
adjustment bolts.

6. 

Connect the Hydro-Guard Unit 

by means of the 2" threaded 
nipple and supplied hose 
adapter.

7. 

Open the hydrant’s valve in 

order to charge the hydrant.

flow away from the Hydro-Guard 
Unit or to be absorbed by the 
surrounding soil. The Unit’s ground-
level erosion controlling splash 
plate is designed to disperse the 
water energy from the discharging 
water and reduce the risk of 
erosion from around the base of 
the fire hydrant. In order to prevent 
undue pooling of the effluent water, 
multiple nightly flushes are effective 
in managing discharge volumes.

8. 

If the HG-6 has been shipped 

with the Dechlorination System; 
remove the security screws at 
side of unit to access, remove the 
dechlorination chamber, open, fill 
with sodium sulfite or ascorbic 
acid tablets, reinsert and replace 
security screw.

9. 

Disinfect the Hydro-Guard 

Automatic Flushing Device in 
accordance with the utility’s policy. 
Do not exceed the dosage and 
contact times recommended 
by the American Water Works 
Association.

10. 

The Hydro-Guard Automatic  

  Flushing Device may now be 
  programmed and placed 
  into service.
