I am adding an additional bathroom on the 3rd story of my house. I ran new water lines from the 3rd floor to the basement and tied into existing cold and hot water lines. The existing lines are PEX and I used PEX to tie in. When I turned the water back on it appeared that all had gone well, nothing was leaking. A while later I noticed that one of the toilets on my main (2nd) floor did not refill after being flushed. It made a bit of a gurgle as well as if something had moved in to block the water flow. Within that same washroom is a vanity which works fine and beside that bathroom is a laundry closet and the washer also appears to be working fine. These would all be on the same cold water run. I shut off my master valve to the house and drained the lines from a faucet in the basement. When I turned the master shut off back on, the tank of the problematic toilet filled up without issue. After 3-4 flushes the problem came back. I repeated this process 2-3 more times and the problem persists. Does this sound like something physically blocking the shut off valve or could I have screwed something up in the system when I tied in the new lines. Could I have some sort of air lock?
