Might not be your check valve. In your water closetcdo you have a selector knob for your water? I believe it says "normal, tank, city, winterize" on it. My fresh tank was filling overnight and I thought it was the check valve as well but it turned out to be that selector knob. There is a cartridge behind that knob with a bunch of o rings in it to line up with different water hoses to go different directions and it wasn't sealing properly.
Ranger man is correct, if your coach has the Anderson 4 position valve it is very common for it to leak back into your water tank and cause the overflow condition. Very easy to replace if necessary. Most common cause for blowing the o-rings is turning the selector valve while there is pressure in the system.
Unfortunately I'm not able to access the water valve since it's behind a panel box outside under the frame on the driver's side, class B motorhome. I have looked to see how to take the side or bottom of this panel box off to no avail. I figure I try the in line check valve first and if that doesn't fix it, then I have no choice to take it in to an RV repair shop and let them figure out how to replace it.
