Plumbing question

[mikeandjenn99]

Are flexible lines like spa lines quieter than hard pvc for the plumbing? I have hard lines right now, and I can't get the plumbing to quiet down. It doesn't sound like a toilet flushing, but I just always hear the water falling down the pipe. I figure maybe it's because of the joints making the water more turbulent? I have a Hofer gurgle buster set up in the overflow, but I still have noise

I use "poor-man" sump hose, that whatever 2"-3" black corrugated stuff and no snail-teeth on my overflows = quiet.
I'm sure the corrugation and flexibility of the hose absorbs a lot of energy and it eliminates any straight falls of water.

I do not envy those folks with basement sumps and 8' heads. That is a serious column of water with a lot of inertia. No wonder they sound like a carload of kids all hitting the bottom of their shakes at once.

I can hear it if I put my ear to the hose. All I can hear is the skimmer discharge and a worn-out impeller on one of my PH's clattering a bit.

anyone else?

Yes, flexible lines are quieter for the reasons stated above.
PVC can be silent though. The main thing you want to avoid is air bubbles. This is where a majority of the noise comes from. The flexible lines have a tendency to offer less resistence which in turn reduces the amount of air bubbles.
