§ 941.08. Testing procedures.

The following procedure is to be followed during an annual test and inspection.

(1)

All hydrant discharge port caps shall be removed, threads cleaned and lubricated, gaskets checked and replaced as necessary, and caps reinstalled and tightened to five to ten ft./lbs.

(2)

The auxiliary or branch valve shall then be located, exposed and valve wrench placed on the operating nut.

(3)

The 2½-inch hydrant gate valve (in the closed position), and the diffuser/flushing elbow, shall be installed on the hydrant.

(4)

Open the hydrant main valve. The number of turns to fully open the valve shall be counted and recorded.

(5)

Slowly, open the hydrant gate valve until it is fully open. Flow the hydrant full open, until the water runs clear.

(6)

Operate the auxiliary valve wrench SLOWLY and close the auxiliary gate valve. Count and record the number of turns.

(7)

Reopen the auxiliary valve until it is fully open. Turn the wrench one-half turn back.

(8)

Slowly close the hydrant gate valve until flow is reduced to 25 G.P.M. or less.

(9)

Inspect and replace if necessary the grease fitting on the hydrant operating nut. Using the grease gun grease the hydrant-operating nut.

(10)

Close the hydrant main valve. Count and record the number of turns. The torque required to operate the hydrant main valve shall not exceed 100 ft./lbs.

(11)

The hydrant-operating nut shall be turned back one-half turn from the fully closed position.

(12)

Observe the rate of drainage to ensure the drains are working properly and all water drains from the barrel of the hydrant.

(13)

Remove the 2½-inch hydrant gate valve and the diffuser/flushing elbow from the hydrant and replace the 2½-inch cap.
