Need help! I hear humming noises when I turn on any 2 or more faucets (toilet flush with turning on faucet or a kitchen faucet along with an upstairs faucet). Only one faucet or one toilet flush no humming noise will occur (only happens when on together). I've shut off the main drained all water in house re-opened (completely) the main and still humming noise when I open 2 faucets or more. One thing that does differ from having two outlet running at once is when I turn on the hose bib in the front of the house. This humms regardless if nothing is on. I turned off all three bathrooms and opened 2 faucets and still humming noise occurs. I checked the pressure and adjusted it to 75psi (was at 100 psi, did this approx 2 months ago). The house is a 2005 and has PEX piping. I have no leaks in the area of the water heater. Not sure what to do. Change out all washers in all the valves? Please help!

Thanks, Alberto

When you say,

I turned off all three bathrooms

what, exactly did you turn off?

Turned off the water supply knob for each toilet. Sorry for not being clear.

Is the humming louder in one spot? Humming equals vibration, can you feel anything by touching the pipes? Smells and noises are the hardest to track down when you're not there. Describe the noise. Deep? High pitched? Loud? Can you nail it down to a single room or location? Let me know, Tom

It's coming from the pressure regulator in the garage. Would I need to replace it or replace certain items?

You have just located your problem. Replace the pressure reducing valve and all will be well. The spring in your prv has worn out. Trust me, its better to replace the complete prv than try to repair it. Also, I would suggest setting pressure on new prv to roughly 60psi max. Please let us know if this fixes the problem(betting it will). Lee

Congratulations on locating the source. Lee's bang on! Replace the pressure regulator. The house pressure norm is between 40 and 60 PSI with the average house pressure at 45 PSI. Good job! Well done! Tom
