They are conducted concurrently, but they're considered separate tests. You pump up to 155psi and hold it (within 5psi) for 2hrs. Then they pump in the volume of water needed to get back to the starting pressure. The allowable leakage calculated with that formula is a max leakage allowed and...
Thanks for the input. I should have pointed out that it was a 2hr test that passed the pressure test portion, and seems to have passed the leakage test performed immediately following the pressure test. I am involved with the testing quite heavily and am doing my best at keeping an eye on him...
I recently witnessed a pressure test followed by the leakage test. Pressure dropped from 161psi to 159psi for 5,710 ft of 8-inch DI pipe. Is there a way for me to verify the leakage (7.5 gal) theoretically?
I'm suspicious of the leakage number because they pulled the suction line out of the...
Thanks a lot for the help guys. Most of the info has been over my head so I forwarded this post on to our electrical guru so we'll see what he thinks. The problem is that the project is in the middle of nowhere (Adirondacks of NY) and the town went ahead on their own and just installed the 240V...
We're setting up a pump station/treatment building. The main load will be a 40hp pump with vfd. The other smaller loads in the building are 3 600 watt bulbs for UV and typical lights/receptacles. Can this run off 1-wire single phase?
