Finding hairline crack in tub
I think I have a hairline crack in our tub or shower surround. We are getting some wet wood under the tub where it supports the tub so I suspect I have a crack. Are there any good methods to find it. ...

Put some of the blue "duck" toilet cleaner in a couple of inches of water in the bottom of the tub. Let it sit for a few hours and if possible flex the bottom of the tub such as when you are in it. If there is a hairline crack the blue will collect in it leaving a darker blue line. Just rinse the tub later to get rid of the blue--after marking it with a grease pencil.
Good idea. Seems hard to find this product. Can I use any liquid toilet bowl cleaner? My tub sits perpendicular to the wall. The faucet is on the interior side of the camper. O water drips from the faucet. My first thought was it was leaking at a fitting where the lines would branch off the main line to run the supply lines to the faucet. It still could be this so I will try to pressure test the lines as well. Tks
