I'm getting ready to put my basement sump into service this weekend, and my plumbing parts showed up today......so everything is ready to go.
My question is this............ How much vinyl tubing should be used between the hard pipe and the return pump?
I have about 1" from barb to the pump, so I'm thinking about cutting the barb down a little to gain 3/4" and allow for a little more space between the two of them. I'm going to use nice soft vinyl tubing, softer then what you find in Home Depot........just to avoid any vibration noise and take any stress off the connections.

For an external pump I would hard plumb with unions.

I have a true union ball valve between the bulkhead and the pump, hard pipe from bulkhead to ball valve, and soft pipe from ball valve to pump.
It takes away any vibrations and releases any angular pressure there might be if things are not perfectly straight.

An fyi, the vinyl WILL stiffen over 1-1.5 years due to its plasticizers (softening agents) leaching out into the tank (bad). Try the bulk reef supply silicone. Or have Jason order us both some  Length: solid 2" between fittings more if possible |

My last tank was set up for 3+ years and the tubing never hardened |

I've used vinyl tubing for years with no ill effects, no stiffening, and no cracking.
At $10/foot, the silicone pipe will stay at the supply house.

I have had vinyl tubing split three different times on me. Once Causing close to 10k in damages, Once in the shop I use to work in and it flooded the sales floor and basement, the third was in a customers house but the sump was in the basement and the basement had a cement floor. Again everybody has their opinions but it is that one time it happens and you will be kicking yourself in the ass. I have hard plumbed many systems and have never had any problems with vibrations or any angular pressure because of things not being perfectly straight.

I don't understand how a vinyl hose cracks and causes $10K in damages. It doesn't spontaneously burst. It hardens over time, begins a slow leak that progressively gets worse. For guys like us that are constantly looking at our tanks I can't imagine a vinyl hose causing complete failure...slow drip that gets noticed pretty quickly and replaced.

The hose was coming off a nipple on my return pump and had a spring style hose clamp on it. The hose split on the first barb under the hose clamp forward opening up a slice about an inch and a half long, the split opened up like a zipper. As like Murphy's law I was at work.
