Should I play with the PRV adjusting as I mentioned above - or just call my plumber and he'll probably replace the tank he installed 10 years ago. This vibration is that of a pure tone with a frequency equal to 3000 Hz, meaning over the highest frequency of the human voice (soprano: 2. There IS a small blue plastic cap covering something on the very bottom of the tank. It reads 'AMERITROL', 'Therm - X - Trol', '40 p.s.i.', 'for the absorbtion of expanded potable hot water up to 200 degrees.' I don't readily see a Schroeder valve - but I don't know what I'm looking for. The tank's connected to the cold water line with a soldered connection. My plumber installed a shut-off valve on the line closest to the tank, to facilitate installing the tank. My 'tank' is mounted up between ceiling joists - conveniently close to the cold water line on which he mounted it. Adjust the screw slowly until the ringing stops Turn on a faucet to start the ringing soundģ. Draw a diagram to show the wave pattern of high pitch note and a low pitch note, but of the same loudness. The frequency of sound waves in water is.

It has a cone on top and what looks like an adjustment screw coming out of the top - with a lock nut lower down on the screw.ġ.

I may have a PRV on my water line right now. If this has proved helpful please remember to hit ACCEPT, otherwise I do not receive credit. This should address the noise you are experiencing. The PRV valve can be purchased for about $50 to $60 worth of parts and then you can install it on your incoming water line. You can get a pressure gauge for about $11 and hook it up to a hose bib and get an instant read as well as a maximum pressure read on a second needle. The PRV allows you to reduce the pressure to a more reasonable amount, say 65 PSI. High pressure can make noises in your system and put a strain on your fixtures and valves. High pressure can vary through out the day.

Pulsatile tinnitus calls for a medical evaluation, especially if the noise is frequent or constant. This device allows you to reduce incoming water pressure from the city line entering your house. Tinnitus that's continuous, steady, and high-pitched (the most common type) generally indicates a problem in the auditory system and requires hearing tests conducted by an audiologist. Check and see if you have a pressure regulating reducing valve on your incoming domestic water line. What you probably have going on is high water pressure. Available at a good plumbing or home improvement store.

It may have an internal bladder that is shot. If it has lost the charge it can be recharged if there is a schroeder valve on it to hook an air pump up to.

It is designed to hold a charge of air to handle the pressure increase. Check the expansion tank that the plumber installed.
