WATER FLOW TEST KIT

STYLE 9015

OPERATION

1. Determine criteria for your testing from NFPA or ISO publications, or other authority.

2. Connect Test Kit swivel inlet to hydrant or other fixed 2 1/2” discharge device. (For best results, the test kit should be preceded

by minimum 3 foot long straight, open 2 1/2” waterway.)

3. Loosen thumbscrews and rotate pitot blade out of stream position.

4. Select from the Discharge Table, the preferred tip diameter for the expected flow. Install the tip as follows:

a. Unscrew lock ring.

b. Pull out gray tip. (Caution: do not use tools which may damage waterway).

c. Insert proper size tip completely until retaining ring is snug against nozzle body.

d. Screw on lock ring clockwise until tight.

caution:

failure to replace lock ring may allow tip to

blow out, causing damage or injury.

5a. Hydrant: Open hydrant and flush rocks, etc. Rotate blade back into center of stream and tighten thumbscrew. Record

pressure reading.

5b. Pumper: After warm-up, bring pump up to desired speed and close throttling valve(s) to set discharge pressure at required rating.

Rotate pitot blade into stream center and tighten thumbscrew. Record pressure reading.

6. When hydrant or pumper must continue to operate (e.g. endurance test), rotate blade out of stream between readings to reduce

wear and avoid damage.

7. Read flow at intersection of tip size and pressure in Table. DO NOT apply additional hydrant coefficients since the nozzle tip

replaces the hydrant outlet as the orifice.

8. After use, open bleeder valve and drain any water in the pitot air chamber. Draining is especially important in freezing weather.

NOTE: When ordering replacement tips check retaining ring (#17) and O-Ring (#19)

WATER FLOW TEST KIT

STYLE 9015

PRECAUTIONS

1. Follow instructions in NFPA 1911, Acceptance and Service Test of Fire Department Pumping Apparatus, NFPA 291 Fire Flow

Testing and Marking of Hydrants or NFPA 1901 Automotive Fire Apparatus to promote safe and valid testing.

2. Mount the test kit nozzle securely. Never attempt to use the tester “hand-held”.

3. Direct the stream toward a cleared space that will remain clear throughout the test. This precaution is especially important when

testing hydrants along travelled streets and sidewalks.

4. Give the pressure gauge a “tug” after making quick connect to assure that the coupling has seated before pressurizing.

5. Use caution around the high velocity water streams and moving parts of the test kit.

6. Check all hose and apparatus connections before pressurization.

7. Do not attempt to interchange tips with stream running or pressurize a tip without lock ring secured in place.

8. Pitot blades are delicate and expensive. Replacement may require return of the entire kit for factory recalibration. Always flush

hydrant or pumper before inserting blade in stream. Do not drop blades or place them where they might be stepped on.
