Vibration from water well pump heard on floors above

[Bucky Plumber]

That sounds like something best left to a professional or is there any easy way for a novice to do that?

Sometimes the vibration is from a resonance. The length of pipe can accidentally be the right length to be tuned exactly to the pump resonant frequency. Shortening or lengthening the drop pipe even a foot or two will usually stop that. Adding a flexible piece also works.

The short piece of flexible tube dampens and also cuts the antenna length of the pipe.

So that would be a flexible piece like below on the pipes in the basement? I was thinking the length of the well pipe needed to be adjusted.

Others have been suggesting this also. I have tried several attempts to dampen the vibration on the basement pipe without success so I am skeptical that this will work.

Cut the pipe somewhere above the junction boxes there on the wall.
Buy a short flex hose such as one for a water heater or water softener, with the correct size female fittings.
Yours looks like 3/4 iron pipe size but not sure.

Buy two sharkbite or brass compression adapters with that same size male threaded ends.

Cut out a section of hard pipe, attach new adapters, attach flex hose to them.

Be sure to protect junction boxes and everything else from water while doing this.

If you are afraid or can’t make a decision, call a pro.

It's been awhile, any success fixing this vibration? I have the same problem, a consistent, low-level vibration that can be heard through out the house when the well pump kicks on to bring the water pressure tank back up to pressure. It's not a knocking. I know hammer arrestors are made to stop knocking caused by sudden changes in pressure at valves, but I wonder if an arrestor installed on the mainline, after the pressure tank, would fix this low level vibration problem. Any thoughts on this? Thanks in advance.
