plumbing hum how to reduce ?

[polywise]

So,
I have a hammerhead hooked up in my fish room, and the pipes are humming. Any Ideas how to reduce this type of noise?
pipes are 2". Any input would be appreciated.

i think BRS has some vibration pads that you can put under your pump or you can try a mouse pad or 2. i have the same problem with my Goby pump

Flex hose on the pump inlet and outlet.

pump is already on a rubber mat
too late for flex hose

is there some kind of wrapp that I can put around the pipes?

Just curious, who is BRS?

Wrap won't help. It's not too late for flex. You can cut the pipe near the pump. It doesn't have to be long, just a few inches so the pump vibration does not transfer to the pipe. It's the quickest, cheapest, easiest, most effective solution.

Hi guys,
Plumbing is rather tight, and don't want to cut it up.
I did, open up the through hole in the sheetrock that that the plumbing passes through, and made sure that the three pipes in that area were not touching, eachother as well. It helped tremendously..

Wes,

The noise/hum is still there, alot less than before, but is something I need to try and reduce more. I have limited distace between the in side of the pump and the fitting to the sump. The out side is not a issue.
What do you think would be a minimum distance to try and dampen the vibration hum?

as little as 2" of flex between pump and hard PVC will help a lot. More is even better. The flex will absorb the vibration instead of causing your hard PVC to vibrate

I dont think there is a minimum distance in a situation like this.
You are looking at a situation where the longer the flex tubing the more vibration it will dampen. A foot would be ideal, two feet would be more ideal.
Can you put up some pictures of the installation, that could help a lot.

The only way your going to reduce the noise is to softpipe it a bit after the pump and before it. The sound is the pump vibrating through the long length of piping. Wrapping it in something sound proof will only go so far and your most likely going to still hear it.

Jim, if you need some 1 1/2" flex...I have some to give you

I used those rubber couplings that they sell at home depot for my hammerhead so I can easily take the pump off my sump if I need to, I basically use it for the same purpose as a union and to dampen the noise.

Alfie, thanks
(I orderd some last night, along with some fittings and stuff for this attempt).

Imbarrie, I'll get a couple of pictures off later today when I get back home.

I hope this helps...

I reduced the noise by using the flex hose and made sure that the hose allowed the pump to not touch the bottom of the sump. In other words I hung the pump using the flex hose. To test to see if this would work just lift it off the sump and see if the noise is reduced. I worked for me. As long as there is vibration transfer to some place the noise will be more noticeable.

trivan, I am working with a external pump (hammerhead)

Haha, I missed that part.

here are the pics of my current plumbing.
Will be modifying later in this up and coming week

I hope this re-do works

Why did you oversize the intake and return lines? both are bigger than what is on the pump and that's alot of pressure loss. Also, you might want to install that check valve vertically.
