So the diverter spout stick thing broke off our tub faucet so now the water won't be diverted from the faucet to the shower. I do believe it's a slip on faucet, but it looks like the set screw has been grouted over for some stupid reason, so I can't even access it. Is there any way for me to get that off? No it's not caulk, it's grout or cement... no clue why...
