either will drain back without a check valve. the up and over won't affect
the drain back in the least.

Please condsider run the discharge pipe UP, and then over. Inverted P

That will help to keep the water from draining back. Please forgive the
crappy art.

This kind of thing drains back:

Well it's at it again. We got a new sump pump and now it's doing the
same thing the old one was doing.

The water level in the pit is low, but high enough to trip the pump.
That's fine the pump starts, and pumps out some wayer ( needs to go 7'
vertical than out the discharge).

Problem is, that 7 feet is enough to empty the pit enough so the pump
shuts off. I can only assume the check valves don't work, because the
pit fills up enough again to restart the pump. This happens every 2
minutes or less.

It is just recycling the same water over and over. The electric
company will love me

Any ideas on how to fix this? Thsi is our THIRS check valve. I can not
imagine these are designed so poorly.

The checl valves are made by Flotec. The pump is a Rigid brand that
was purchased at Hiome Depot about a year ago.
