Silicone vs vinyl tubing?

[W1ngz]

I've just gotten the return pump started on my new system. The return pump is connected to the hard plumbing with a piece of vinyl tubing, because that's what I was able to easily get a hold of. It's quiet, but there's still a noticeable hum from the sump due to the pump vibration.

Does silicone tubing do a better job of dampening vibration than vinyl?

Yes, you will notice a difference.

my guess is that it's noticable if you are paying really close attention, but that it won't completely silence the issue
like going from 40 db to 37 db for example

I put my return pump on a silicone hot pad to isolate it from the glass bottom of the sump.

Thanks, but the pump already stands on ~1" tall suction cups. The vibration is being transmitted through the tubing to the bulkhead.
