There are pros and cons to having a sump just like everything else. If you pump to much and your overflow can't keep up you'll run your pump dry and more then likely the tank will overflow. If you siphon breaks your pump will keep pumping and again your tank will overflow. If your sump area isn't big enough you take a chance of it overflowing. If the power goes out when your not around your sump area will overflow again if its not big enough to hold all the water. When the power comes back on more then likely your siphon would have broke and the pump will kick back on and the tank will overflow.
Now the only way around it is to add a ball valve on your return line and a thing that stops the water from siphoning back down that line. I've drawled a blank on what its called but its found at your local hardware store. This way if it pumps to fast/much you can control the water flow with the ball valve. Your better off with an drilled tank with a straight pvc
line to overflow due to there is no siphon. Or you can do what I do and only run it when your home to be safe. I've had a few screw up on me and its not fun when all the water is everywhere.
This is the link to a ball valve so you know what they look like
