foam to dampen return pump vibration

Mike de Leon · 03/18/2016, 10:32 AM

Do you guys think this is safe and will not break down and leach chemicals?

moondoggy4 · 03/18/2016, 12:38 PM

Have you tried silicon?

Harry_Y · 03/18/2016, 12:51 PM

Get a silicone pot mat

Mike de Leon · 03/18/2016, 06:15 PM

Looked it up. Will pick one up shortly. I thought, if this one worked didn't have to buy another item for the tank...
Thanks

Target sells them

I got several silicon pads at bed bath and beyond for like $1 each.

OK, Thanks for the hot tip! In this hobby we can take all the break that we can in spending our hard earned cash!

You didn't say it was or wasn't, but if it's hard plumbed, no matter what pad you use it's gonna make noise.
Add a piece of silicone tubing between your pump and plumbing.

Really? I am thinking hard plumb.

If hard plumped the noise will resonate thru the PVC. The PVC will also amplify the noise. You only need a foot of silicone tubing between your pump and the rest of you hard plumbing.

What about some flex pipe in between? I also have a manifold to install.
See link. This is also suppose to be PVC. Can this be glued??

That will help, but you will get the best results from silicone. An added bonus is the silicone tubing is very flexible where as some of the flex pipe isn't. But either way, it it be better than hard piping right to the pump.

Agreed that you'll get the best isolation with silicone tubing, but any tubing requires a barb connector that will cause significant head loss unless you upsize it significantly. A section of ultra flex PVC can cut the vibrations without the head loss issue. Also, adding some rubber or silicone padding between the pipe and stand will help prevent vibrations from resonating through the stand.

Mike de Leon · 03/19/2016, 08:03 PM

What do you mean between the pipe and stand?

RMD photography · 03/20/2016, 10:13 PM

My return pump is hard plumbed, sits on a silicone trivet and is silent.

sleepydoc · 03/21/2016, 10:41 AM

I had my pipe anchored/supported by the stand and the stand acted as a sounding board, transmitting and amplifying the vibration in the pipe. A piece of rubber gasket between the pipe and stand eliminated the noise.
