the pipes in my house have recently started to shake when 2 or more fixtures are turned on at the same time. you can see a noticeable drop in water pressure at the taps. There is a PRV already installed at the supply line before the water meter. when the toilet is flushed there is noticeable surging sound in the general area of the water meter and the PRV. adjusting the prv up or down does not change the surging sound, but once fixtures are shut off the sound stops.Could this be a bad PRV, or is it possibly something wrong with the water meter?
