Water Off = no noise.
Water full ON = no noise
No problem.

Water at half throttle = noise.
Why would you open a shut-off only half way?

That's the spring loaded mech in the regulator chattering at 1/2 normal flow rate

Thanks for the reply.

I opened it slightly to show the noise while I Was in the crawl space. If any faucet is on less than full it makes the noise. Also when any faucet is turned on and off it makes the noise. I installed a Heat expansion tank and it made no difference.
