Why is water leaking from the roof all over the floor of this new building?
I’m getting my above ceiling rough-in inspections, and we’re required to use water to test PVC waste lines and vents.
Years ago, we filled these with 5 pounds of air, but that’s not allowed anymore because of the danger of the pipe exploding.
The plumbers put a boiler drain at the bottom of the vent pipe.
I connect one end of a washing machine hose to the valve and the other end to my cordless Milwaukee pump.
This pump actually has enough power to push water to the top of the pipe above the roof.
As soon as water starts to spill over, I shut the valve, then turn off the pump.
Now the pipe is filled right to the top.
When the inspector comes- they can shake the pipe- if water comes out they know it is full, and there are no leaks.
This way the only person that has to get on the roof is the roofer when he comes to install this boot to make everything watertight.
After I pass inspection, I attach a garden hose and drain the water out.
Earlier I was taking a test plug off at the other end of the warehouse and there was some water trapped that didn’t come out the drain - unfortunately I soaked the camera lady. @hausplans
