Filling the water main prior to hydrostatic pressure
testing
Fill the water main following the recommendations
1.
of the American Water Works Association (AWWA).
These recommendations can be purchased on
line at the AWWA website at www.awwa.org. Also,
refer to the pipe manufacturers recommendations.
Improper filling of the water main can cause
damage to the water main and can be a safety
hazard.
WARNING!
2.
It is important to get as much air out
of the water main prior to testing as is possible.
Air is a compressible gas and can turn your water
main into a potential “bomb” causing extensive
damage to the water main and injury or death
to workers in the area. If you are pressure
testing the water main and it is taking a lot of
water to bring the pressure up, abort the test
immediately and recheck the water main for
trapped air.
Note: Since water is nearly incompressible, it will not take
much water pumped from your Old Faithful Pumper to bring
water line pressure up to test pressure. For example, if you
had an 8 inch water main, 1,000 feet long and all of the air
was removed or purged from the water line, it would only
take about one cup of water to bring the pressure up to
150 PSI. WARNING; IF YOU ARE USING TOO MUCH WATER,
ABORT THE TEST IMMEDIATELY AND RECHECK THE
WATER MAIN FOR TRAPPED AIR.
Old Faithful Pumper Operation Instructions
Read Engine Manufacturers Owner’s manual
•
for operation. Check Oil and Gas levels in your
engine.
Refer to the Hypro Medium or High Pressure
•
Pumps manual for specific instructions for
pump operation. Check all fluid levels.
Connect the clear suction hose to the filter
•
assembly on the pump. Be sure to insert the
safety clip into the coupling.
Put the open end of the suction hose in to a
•
barrel full of water or if you have purchased
the optional water tank, connect the suction
hose from the tank to the filter assembly.
Again, insert the safety clip into the coupling.
CAUTION: DO NOT CONNECT THE SUCTION
HOSE TO A PRESSURE SOURCE OF WATER.
Doing so can cause damage to your test pump.
If you have purchased the optional water tank,
you can connect it to a pressure source of
water.
Refer to Operation Instructions in the
•
Hypro Manual, included with this manual,
for detailed instructions on setting the
control unit. Refer to instructions for the
9910-GS40GI Control Unit used on our
HTP10-500 pumps and the 9910-VDR50
Control Unit used on our HTP23-700 pump.
Before you start the engine, raise the pressure
•
release lever. This will take pressure off the
pump and make starting the engine easier.
Start the engine and let it run for about one
•
minute. Turn the engine off and recheck fluid
levels on the pump and the engine.
You are now ready to make a connection to
•
your water main.
Hydrostatic Pressure Testing Steps
Hydrostatic pressure testing will help you quickly determine the quality of installation of your water mains. Done right,
