Hello, I have a 5 stage BRS RO/DI unit hooked up to my apartment sink….when I turn the water on, the pipes under the sink make a humming noise and the intake line starts to jiggle. It will eventually stop but comes back quickly. This wasn’t a problem in my last apartment, so maybe it’s a plumbing issue? Any advice as to what to do since I obviously can’t repair the pipes myself since I’m renting, and I don’t want my apartment to blame me for “breaking the pipes from my RO/DI unit”.
