Can't find second valve

Hello all,

 I am stuck trying to find the second valve on Shark Archipelago. I have been through the walk-through and the second valve is not near the top of that tree on yellow island! (3rd island you transport to) I have gone back several times and scanned this island without results. I accidentally started the level over, so could the second valve be somewhere else? I got to the 4th island (blue island)  with only 1 valve. Cannot get those aqua lungs without the second valve, as I don't have the second one to put into that second faucet! Any help is appreciated!

Found valve by re-starting the level again!
