I have all of my vertical pipes capped except my laundry drain. I have a test plug that blocks the entire system from the existing drain.
There are 2 vents, 1 that connects to an AAV and one that connects to an existing vent that exits the roof.
I thought I could fill my system via the laundry pipe (my highest drain) and assert the system does not leak, but I'm reading conflicting information.
It sounds like I may need to fill it from the roof vent? In that case, would I need to plug the other side of the vent that services existing plumbing? is it ever possible to avoid filling from the roof?
And what about the air that is trapped in the system? I did a test run and the system didn't take as much water as I expected, but I suspect there is a lot of trapped air.
Over about an hours time, the water line I see in my laundry pipe has dropped maybe an inch or so, but there are no leaks. Is it the trapped air that is escaping?
Any guidance is appreciated, thanks all!
