Water Line Pressure Testing

The purpose of this standard is to provide the minimum requirements for fbpe coating for steel water pipe and fittings including material application inspection testing marking handling and packaging requirements.

Water line pressure testing.

Though it is not required to pass inspection it is advisable to test the pipes for water leaks as well. The leakage test shall be held concurrently with the pressure test. To find leaks a low pressure 30 50 psi air test is just as effective as high pressure 150 psi. Testing involves pressurizing the pipes first to ensure they hold pressure.

Certified test results for the owner contractor and engineer. Testing is usually done to awwa specifications at 11 2 times the operating pressures unless otherwise. C229 20 fusion bonded polyethylene coatings for steel water pipe and fittings. Pressure testing insures the integrity of newly in stalled or repaired water lines valves and hydrants.

Testing and inspection services performed include. Test a water system without draining it by locating an outdoor or laundry faucet to which you can attach a pressure gauge. For c 900 pvc pipe class 150 the test pressure shall be 225 psi and the test duration shall be four 4 hours. Pressure testing with air versus with water.

The test pressure applied to the water main for the leakage test shall be maintained as constant as possible for not less than two 2 hours. Step 2 screw the gauge to the faucet spout open the faucet all the way and turn off the main shutoff valve for the house. Some homes even have dedicated gauges hooked up somewhere in the water line so homeowners can check the water pressure quickly and easily with just a glance. Pressure testing with air versus pressure testing with water to detect leakage is a common practice in our industry.
