First time winterizing. Current temps in MO. Yesterday 72, today 35. Not a typo
here is the steps I took.
Drained hot water tank. Put RV antifreeze in freshwater tank. Turned on pump. Opened faucets one at a time until pink. Filled P Traps. Because I am compulsive, I checked the sink one more time and it started spitting air and then pink foam, and then some pink, then nothing. Bathroom sink and shower ran fine but the toilet also foamed and trickled pink. Scratching my head. Then went out and my grey valve wouldn't open (35 degrees). Opened city water connection, pulled the screen, pressed the valve and nothing came out.
Did I do something wrong here to cause air, foam?
