Check Valve
I am setting up my sump (1st time ever), I want to install a check valve, my questions is do I install the valve on the line going in to the sump or on the line returning to the tank? I have never done this before so I want to make sure I install the valve in the right place.

Those check valves fail all the time due to calcium build up

ALL check valves fail because in a SW setup things GROW on the valve seat. If you need a check valve in your plumbing, there is a fatal flaw in the overflow design that you should fix rather than rely on something that is likely to fail when you need it.

I should had mentioned that it is a freshwater tank and I'm going to use it as wet/dry filter.

Install the check valve just after your return pump. This way when your pump stops, the check valve keeps the water above/after the pump from returning to your sump. I have used a check valve in my saltwater set-ups since 2005 and not had a single one fail. I also make sure I understand the volume of water that I need for the sump just in case it was to fail.....

If you need a check valve you are doing it wrong.

Finally I got my wet/dry setup it took my awhile but is working, however, when I did the power failure scenario the water kept on rising in the sump. My current filtration system is a Magnum 350 canister so when I set this up I directed the outlet from the canister to the sump so when the power fails the water keeps on siphoning through the inlet inside the tank, my question is, is there a way to stop the water from siphoning on a power failure situation? I wanted to include a picture but I didn't know how to, sorry.

Create a siphon break by filling a small hole for air to get in.

That's not a very safe set up at all man. It will flow to the lowest point(intake of the magnum) only thing you can do is right below the water line make a siphon break hole to stop the siphon but that will mean your filter will not start on its own because it will be sucking air thru the hole and never prime.. You need to use an overflow box or drill the tank.. There are some diy pvc overflow designs that look ugly but work.. Safely is another question mark on those..
If you decide to get a overflow box make sure you don't get one that rely' on a pump to keep the prime.. Eshopps continuous siphon box is great as well as the lifereef one. They will not break siphon and will automatically restart after shutting down.. I've had an eshopps running for about 5 years and never a single failure fwiw.. Your risking a lot with the setup you have now.. I would Uninstall that ASAP it until it's right.. New floors etc Are a lot more expensive than doing it right in the first place..

You can actually run a bit of airline off your return and back into the tank so the excess water gets squirted back in the system. As long as air get introduced somewhere, the syphon will break. Just make sure the end of the air line isn't ever underwater.

Put unions before and after the check valve so you can easily remove if need be to clean or replace
