correct placement of sump pump check value

i just bought a new sump pump that requires a 1 1/4" hose to replace one that no longer works properly. the existing one has a 1" laundry hose, with no check valve, that discharges to a floor drain. This was set up by a previous owner, even though there is a pvc pipe set up to discharge water. The pipe goes across a foot or two then into the floor, not sure where the water ends up after that. looking at an older non-working pump with a 1 1/4" flexible discharge hose i noticed that the check valve was about a foot above floor level, where the flex hose attaches to the pvc pipe. is it ok to have the check valve that high up or should it be closer to the pump? all the instructions i've come across show it slightly above pump height.

thanks!
