Bought a universal all-in-one fluidmaster repair kit with the fill valve,flush valve. Right out of the box the fill valve height adjustment did not work. The shank just spins in place without actually adjusting height. I tried with the locking ring off, and nothing. With the locking ring on I can't even turn the shank with full force. Went back to home depot to exchange it. Guess what? Same thing...the damn height adjustment isn't working. Do these people QC their products? :vs_mad:
