new return pump

[kien]

What pump are you using ?

What kind of a noise is it making? Rattling, buzzing, humming, whirring, gurgling, farting ?

Is your stand enclosed or open?

Some people will run their pumps in a bucket of vinegar to help break it in. That may help. Some pumps also come with foam pads that you can set it on. If your pump didn't, then you can get some foam at Michael's and strap that to the bottom (and maybe sides) of your pump.
