They can, look into the end and if the hole for flow is not the same size or
bigger adapt to a bigger size. Some are built better than others.

Yes, spring type being much worse than flap, but flap type does have to
be in vertical position. I would try to use a flap type. They also
make electronic valves which are 'normally closed'. These alone can be
more $ than the entire pond.

I use a flap style with a 995GPH pump. I don't believe the flap is causing
any restriction worth measuring. When I turn the pump up to full blast, I
can see the water rolling out of the flap area...It moves it no problem.

Jay is correct: spring loaded check valves will significantly affect the
flow; they also clog (algae gets caught in the mechanism and is a royal pain
in the tush to clean). Most flap valves can be placed up to a 45 degree
angle; just ensure that the flap is perpendicular to the ground, hinged side
down, so it will close with the back-flow water pressure. That's the way
mine is, and it works perfectly.
