Is my back check valve toast?

Last time I camped I hooked the black tank flush up to the water at the dump station without a pressure regulator and had water coming out the bottom of the camper. I'm sure the pressure was more than the back check valve could take.

Is the back check now toast or if I restrict the pressure will it continue to function? I know that a lot of people just remove the valve but I think it is still worth having. Before I buy a new one, how do I know if this one is bad?

Are you sure it is the flush mechanism and not the hose going to it? I'd check that first. It may have simply come loose.

Water pressure less than 100 psi shouldn't really cause a check valve to crack. Chances are slim that a campground would have water pressure above that. I recall reading a thread, a while back, where somebody had a water line disconnect from the check valve. It is certainly possible the valve could be cracked from a manufacturing defect but they should not need a pressure regulator to be connected in line.

In factory installed tank flush systems those check valves are also anti-siphon devices and they are prone to sticking and leaking.

You can try hooking water to it again and see if it still leaks. Other than that, you'll need to remove it to check it.

I am one of 'those' that removed the check valve.
I heard too many stories of failed check valves .

HOWEVER, I do faithfully use an external check valve on the exterior hose connection of the black tank flush.
