Fill valves

[Darren]

The first photo shows a newer toilet with a fill valve that fills the tank thru the tube but also drip down onto the 'float'. Actually I had 2 do the same thing on this inspection.

The second shows an older fill valve I have never seen before. Is this legit or can it create a cross connection?

Thanks.

The first one is easy to fix by pulling the top off,Ive never seen one like the second one in 30 plus years of plumbing.[:-bigeyes
