Why when i turn on my wter in any part of my house, bathroom,kitchen sink, outside water hose there is a viration and a loud sound that sounds like a small train is passing by. and stops about 30 seconds after the fauset is turnede off. What is the cause?

Is your caps key locked or something, this makes it look like you are yelling at us. While the noise is happening try to isolate it to one point. It could be your main shut off valve for the house or even a water filter or water softner.

FIRST OFF, LOSE THE CAPS! We don't yell at each other in here.
We need more details. Is 5there a PRV valve, pressure reducing valve, installed? What's your house PSI?
Where is the noise the loudest? Noise= vibration. Starting at the point of entry in your house feel for vibration and listen fro sound. I need to know exactly where the sound is the loudest and the vibration's the stronges Back to you, Tom.

The pressure at the pressure valve is 90 lbs. and the noise is the loudest it seems at the garage wall where the pressure valve is installed. There is also a clicking noise when water is on. It's in the area of the valve.

Sorry about the caps, I'm not computer knowledgeable, it won't happen again

90 psi is pretty high an could be partially the problem. Adjust your pressure reducing valve down to about 45 psi and tell us if the problems is any better

High house pressure puts a strain on the joints in the pipes and on all the valves and stops. I've got to hunch that once you back off the pressure that the sound will go bye-bye. Then average house pressure is between 40 and 60 PSI with the norm at 45PSI. Good luck, Tom
