Just purchased new sump. Going to set up in basement Approx. 10' below display tank water level. I think I should run rigid pvc from display tank to just below floor level in case of a leak. Then would like to run about 6' of flex to the sump. Does this make sense? What type of flex could I use? I have seen the semi rigid looking flex, and also the tubing type of line. What would be best? And where to purchase? Thanks ???

What do you mean by tubing type of line?
All my stuff is hard piped the only flex I use is on my skimmer, and in the display stand to go to the bulkheads.
The flex is called Spa flex
Some Lowes have it
I have never seen it at HD
It is also used alot in the boating industry
What kind of pump are you going to run ?
How big of pipe are you going to use?

Display is 54 gallon corner. 1" overflow line, 3/4' from pump to display. Am using a coralife turbo-sea 790-p high pressure pump.Yes I am going to install check valve just above pump going up to display,also a ball valve for regulating pressure.Does anyone see any of this as a problem. Also I have to put 2 45 degree angles on the 1" overflow line is this OK? Sump measures 36" wide x 15" x 16" high. Uncertian about volume of water.
You might want to use flex for the 45 degree connections that way it would be gradual
You might have to run the sump pretty low so it does not overflow when the power goes off
When my power goes off I probally have 25-30 gallons comming back to my sump I use all 1.5 pipe
Dont underestimate the amount of water
Also if the check valve fails it will overflow

I would up-size the return line to reduce the additional head caused by friction loss. Also, over time the overflow line will build up stuff inside reducing the flow which could ultimately lead to a problem at the display with more water coming in than what is able to exit. Therefore, I would also suggest up sizing the overflow lines as well. Having said all that, be sure you heed Jason's advise and allow for the pipe volumes, and the display volume difference between the pump on and pump off water levels in your in your sump.
Mcnaughton's in Somers Point 601-1616, had black spa flex in almost every size including 3/4in. I was there last Sunday picking some up. If you have a local garden center you might call them first as they are gearing up for spring and outdoor ponds etc...;D
It might be a little late for this comment but I think your sump @ 31 gallons is way to small to be in the basement. You might have a big problem with bubbles being returned back to the display. Also a 1" x 10' long pipe has about 1.5 gallons of water in it times 2 for the return gives you 3 gallons of water in circulation. I suspect that you will have to run the water very low in the sump to keep it from overflowing when the power is off. Running the water very low increases the problems with the bubbles and also may cause whirlpool at the pump intake also sucking in air.
I would suggest that you install baffles in your current sump and use it as a settlement filter set slightly above a much larger sump like a rubbermaid tub.

How's the setup going? Did you get everything hooked up? You might want to consider gravity feeding the skimmer from the overflow and drop the skimmer output into the sump? That would eliminate the cost of a second pump and having to drill the new sump.
