Can you drill out the setscrew and clean up burred faucet threads with a
small triangular file?

At least on mine it was easier to use a fine saw to notch the backflow
preventer on either side of the setscrew and then break out the screw.
The body is brass and not very strong, the screws are relatively hard.

The saw cuts did no substantial harm to the faucet, the setscrew galling
was minimal and easy to file out.

Did you try to disassemble the check valve?

I've permanently (?) repaired hose sprays by winding a new rust-proof spring
from stainless welding rod.
