Ok so I moved the shower drain, ( made shower bigger). How do you check for leaks. Other than filling trap with water, that will work for two joints. Would like to check the joints at short extension. I'm confident it would not leak applied glue to
Pipe and socket. Mostly curios how to check if it had to be proved out to inspector.

Thanks for any and all comments,
Phil

Cap it with a gauge and air valve, something like 6 pounds for 8 hours. Do not remember. Now you would have to close off every fixture and vent in the whole system.

Static water test, find the main plug it with a test plug and fill the system with water at its highest pre flood level. what you simulate is a stoppage.

or you install a test tee after your last connection insert test ball past the last joint raise the drain 5 feet and fill with water. water collum test

Since very few fittings are altered, I would get away with a "running test". Stick a garden hose in there and run water as fast as the pipe will handle.
Standard test would be a 10ft water column(4.8psi)
