I didn't know a better way to say it, but its not actually the caulk around the tub to seal it.
Its the faucet for the tub. We have a Jacuzzi style tub, much a faucet like this one. The seal was coming off and finally broke. Now, we can run the water through it fine with a seal, but it leaks and we can't turn it up high. We tried to seal it with some clear tub seal stuff, but it just didn't work.
When it comes to sealing faucets, what do you use and how should I do it?
