850 windshield washer check valve cleaning

I noticed that fluid was squirting out the check valve hole. I took it apart and it was all gunked up. It is all clean, but something doesn't look right... the black valve/stopper has a pin sized hole in the center of it, which looks original, but doesn't make sense to me. That would seem to allow air into both the squirter lines AND the supply line, not to mention fluid to squirt straight out the hole in the red cap. Is a hole in the black thingy normal, or has it developed?

There's a diaphragm held against the pipes with a small spring to stop any fluid from leaking out that hole. If yours is bad, you'll need a new check valve.

Unless the design has changed, what you are calling a diaghragm I was calling a valve/stopper. I realize this was an obscure question. Who has a check valve sitting next to their computer... who remembers what the black diaphragm/stopper/whatever looks like. I think the hole in mine shouldn't be there, it is just weird that it is there. I doubt someone stuck a pin in there, and I doubt the supply line pressure could have bored a hole in it. Gremlins perhaps?

I call the whole thing a valve, and what you call a valve/stopper I call a diaphragm. In any case the latter shouldn't have a hole in it.
