    As far as I can tell my Pentair MPV makes no noise at all. Since you have two of them doing it, it sounds like something in the system causing it. If it is air it has to be getting into the system somewhere and I'd start by trying to resolve that. A high flow rate will also cause some valves to make a noise. Have you changed anything recently (besides the MPV's)?

    Tell us a little more about your equipment. Hopefully someone here will have experience with the cause of your issue.

    More details please. A pic of the equipment pad and plumbing would be helpful. Descriptions are needed too. Otherwise we are just guessing wildly.

    Re: multiport valve noise

    only thing i am a little concerned with is my installer installed a 1 1/2 multiport valve and my pump is 2 inch, then plumbing had to be reduced down to 1 1/2 inch coming out the pump i know that had to increase pressure but that is all. when then valve cracked at the gauge port i just replaced it with another valve just like it.
