A check valve is your answer.
YEAH, YOU PUT, oop`s ,, a check valve in the line.
Yes. You need to install a back flow prevention device, otherwise known as a check valve.
This will plumb in line of your discharge pipe and has a spring loaded valve inside that will open when the pump is discharging but prevents water coming back in.
Here’s an example.’

in most cities that would be considered an illegal connection, check it out first, if it is allowed, great…all you would need is a check valve and you probably already have one on the pump.
you use a swing check . spring checks are not a good idea on a sump pump . but it is surely an illegal connection .
There are ‘back-flow preventers’ or flapper valves sold for
the purpose.
IDK how well they might perform in dirty water
and under sustained pressure though.
If you have storm water drainage, why not rout the outflow
from the sump pump to that, outside and have an air gap.
