It's a catch 22. You don't need to be there as long as there are no leaks. If they run the pressure test and there is any drop in pressure (even a slow leak), they will lock the meter, tag it, and require you to get a licensed contractor to fix prior to them turning it back on. I learned this the hard way last winter. 4 days with no hot water. For the hassle and time I spent getting it turned back on I would have gladly paid a licensed contractor to handle the work in the first place.
@Seth Teel I thought I was supposed to supply my own pressure tester, and install it myself.
So the city inspector will add air to the line and check for pressure him/her-self? I tought they were only supposed to check the gauge and maybe release some air to make sure it still holds air.
I checked the pressure and it can easily pass the 15 psi / 15 minute test.
but this property is already red-tagged, and I need to make sure I get the clearance with CPS Energy cause I'm already under contract with a buyer.
If it is already tagged and you are acting as homeowner, you can install the pressure tester, they will come by and check it. Again, if they detect a drop in pressure beyond a certain PSI, then tag goes back on and license contractor must be present for next test. My experience may be a little different because I was living in the property and originally called CPS for a smell of gas (worst idea ever). I should have just called my plumber.
Sounds like you're in the home stretch. Good luck.
