Checked on my windshield washer today after having plugged a leaking fluid container. Turns out I have a hole in the washer tee between the two nozzles where the water is shooting out. Is this supposed to happen? The hole looks like it's designed to be there and there's a second hole on the opposite side of it, so I was thinking this was a failsafe of sorts, but wanted to get an opinion here before trying to change it out. Should I change the tee or is this a sign of a problem elsewhere?
