Hi folks. I was replacing the water shutoff valve to my toilet downstairs. I opened the sink faucets upstairs and downstairs to relieve the water pressure so the water wouldn't pour out while I'm working. But I forgot to close the valves to the two upstairs toilets, and eventually noticed that water was draining from those tanks into the lines. Yuk, I know the tank water is not the cleanest and don't want it showing up at the tap. I ran the water for awhile and hopefully none of it remains in the lines.
Is this really a concern? Should I be shutting off all the toilet valves when I need to drain the pipes of water? I've not seen it mentioned in do-it-yourself forums. Thanks.
