I recently took my LifeReef skimmer apart for a good cleaning. My screw was rusted badly, I couldn't get the screw out with a screwdriver.
I took my Dremel tool out and cut what was left of the screw head. The valve handle came right off, you really don't need the screw to secure the valve handle. But I'm sure you can find a stainless steel screw at the hardware store for 25 cents, no need to buy a new valve.
I'm just going with out the screw.
Hope this helps, I'll atach a few photos I took when I cleaned it up. I also used citric acid to clean it, citric acid worked better for me than vinegar.
Take all..
Interesting idea I clearly didnt think of. Will give that a shot. Worse that can happen is I somehow mess it up and still need a new valve. Thanks for the tip.
Edit: Was able to unscrew the old screw with pliers. Came out in 5 seconds, so there wasnt need to cut it down with dremmel. Thanks again, saved me some time and $
