Toileet question

Toilet valves that spray out the top. See the picture is it normal, I see it a lot. Also is it a big deal when the overflow tube does not have that small water line going to it from the fill valve.

I would suggest fixing it.
The little fill hose is how the bowl water refills so yes ,just clip it back in.

No and Yes, it probably needs replaced. It will sure cut down on the water bill.

Its a defect. Write it up and let them fix it how they see fit. some will replace it. others will leave it.

So I am right the valve should definitely not spray out the top?

correct

Water shouldn’t be spewing out at that fill valve tube. It should have a hose attached to it and conveying the water into the overflow pipe

See the small black tube at the top center of this image…
