Need a little help with this one. Went away on vacation and turned off the water. Always open the sink valves when I do this. When I got home and turned the water back on, also let water run till air was out of the pipes. Now all 3 toilets whistle when filling back up. No other water supply does this. and if you flus a toilet and then turn on a sink, the whistle stops. Cant figure this on out . I have tried all combinations of turning water back off and so forth. Thanks in advance for any help!
