what can i do about pressure spikes in the municipal water supply, that cause my plumbing to rattle?

this ratting in the pipes happens even when the taps are not on!

you could install a water hammer or a pressure reducing valve

    We had water-hammer reducing devices fitted to our taps to stop them banging/rattling but that was only happening when we turned the taps on/off with not enough pressure.
    They may not help much with your problem, but then again I don’t know exactly how they work.
    I’m guessing you’ve already called the water department and talked to them about the problem?

  3. A pressure regulator may resolve this but would reduce the water pressure in your house (whether that would be satisfactory or not is up to you).

    I wonder if a small storage or "expansion" tank would help with this problem. It would act as a buffer and smooth the fluctuations.

    Do your neighbors also have this trouble? Perhaps one of them has found a solution.

  4. water hammer is usually caused by fast acting valves such as a laundry or dishwasher as well as some toilet fill valves. The momentum of the water flowing through the pipes carries through when the valve slams shut. sometimes it can be remedied by installing a few extra hangers on the pipes. A simple fix is to adjust the flow rate on these appliances by turning the valve partially off. Try it then test it. If it doesn’t work, try shutting it further. The drawback is that sometimes the valve might make more noise while running or leak from the packing, which can be remedied usually by tightening the packing nut.
    A more scientific approach is to install a pressure reducing valve to limit pressure to 55 PSI which is more than you should really need. Also, you could try "mini resters" which are available at home depot which will screw on between you laundry valves and hoses.
