Whine in Pipes when outside hose bibs winterized
Anyone have any ideas why my pipes start whining when water's run only
in the winter (when the hose bibs are winterized?) It's a medium-pitched whine with a little vibration. House is a 6 year old three level townhouse built by Centex. Thanks. |

House is a 6 year old three level townhouse built by Centex. Thanks. Easy test: Turn off the supply valve(s) to the toilet tanks. If that cures the whine, the ballcock valve in a toilet is worn out. Certain mfr ballcocks will set up a resonance in the system when worn out. I'm guessing that the extra length of piping to the hose bibbs is somehow damping the oscillation. Jim Thanks for the suggestion. I tried each toilet individually with no success in eliminating the whine. Did you mean close all the supply valves at the same time? If not, any other suggestions? Thanks again. |

I've heard similar sounds from vacuum breakers, but can't say if that has anything to do with your situation... |

Thanks again. Each toilet should have done it. Guess we can rule them out. You may have a PRV (pressure regulator) on the service. If street pressure is high, these can whine as they throttle the flow. It might look like: http://www.cashacme.com/eb75.php Jim |

Thanks again. |

Thanks again. That may be a tough one, esp if street pressure is very high. It's possible that simply replacing it would fix it. Maybe a different brand. Risk. |
