Shut off valve on 1/2' supply line to toilet
Kind of confused and need some explanation. Had to remove the toilet cause we are getting new linoleum installed in bathroom. My supply valve had seized up so I was going to replace it. I shut the main water supply off in the house. I turned all of the faucets on and also the showers. The toilets are the lowest point of water coming up threw the floor to the house. When I drained everything and went to cut the CPVC line there was still a little bit of water that tried to seep out. It wasn't spraying or gushing just trickling out the cut end. I got the new end on without much mess but was curious if it was leftover pressure in the line from a higher water source in house.
