: On an irregular basis, when a tap is used, a high pitched squealing, whining type of noise is heard throughout
: the house. Sometimes it goes away when you quickly run a tap (either hot or cold) and then shut it off,
: but not always. It seems to be getting worse. The only "cure" for it right now is to flush the toilet, but
: this could get expensive if we have to keep flushing to stop the whining. It has progressively gotten worse
: over the past two months and it happens at least once per day. There doesn't seem to be a particular
: faucet that starts it off, and sometimes it just does it all by itself.

: Any suggestions on where to start??

I would check for a PRV "pressure reducing valve" in the system. Turning the adjustment screw in and out may loosen debries in the line.

Second, I would check the toilets. A slowly leaking flapper on a toilet can allow refilling and therefore water rushing through the fill valve. Some old fill valves can be very loud.
