There are many ways that your bathtub may start leaking or having other issues. Continue reading to learn more about what you can do, including: locating the leak, repairing the faucet and repairing the grout and the tub.
Locate the Leak
First things first: You must locate the leak before you repair it. It’s relatively simple to determine whether or not your faucet or grout is leaking – just check to see if water is spilling out of either area. To test if the actual tub has a leak in it, wipe the outside until it is completely dry and line the area with newspaper. As you begin to fill the tub up, you’ll want to keep an eye out for areas of the newspaper that start getting wet.
To test the drain, completely fill the tub with water. When it’s filled, carefully listen for the sound of water seeping out. If you hear those sounds and see the water start to decrease, chances are the drain assembly isn’t fully sealed. Source: Rotorooter
Repair the Faucet
Faucets can be one of the easier items in the house to fix. Pressurized water is delivered to your home, and a faucet turns off by creating a watertight seal strong enough to counteract that pressure. A simple washer and seat assembly accomplishes this job, and if your faucet is dripping, one of these two items probably needs to be replaced.
You’ll first need to shut off the water and pull out the faucet. There should be a washer. If replacing the washer doesn’t fix the leak, then the problem is probably in the brass seat located behind the washer. You can fix it yourself if you have the proper seating wrench, but it would probably be wisest to call a professional plumber with all the expertise, tools and parts he needs to come fix it once and for all. The worst thing you can do in this situation is trying to make the leak stop by trying to force the faucet handle shut. The handle is not the problem. Source: HomeAdvisor
Repair the Grout and the Tub
Small leaks in the faucet grout and tub can be repaired using heavy duty sealant. To repair the grout, clean the leaking area and determine the extent of the problem. If the crack on the grout is minor, you may apply sealant on it to stop the leak. To do so, shut off the water supply to your tub and let the grout dry up completely before you attempt to apply sealant on it. After applying the sealant, wait for at least 3 hours before you turn the water supply back on to give the sealant time to dry up completely.
For small leaks on the body of your tub, you may use heavy duty waterproof sealant to stop the leak. To do this, clean the tub thoroughly, then mark the areas that need repairs. Apply an ample amount of sealant on the cracks and let it dry for at least 3 hours. Once the sealant is completely dry, use fine grip sand paper to remove the extra sealant and smooth out the surface of the tub. Source: DoItYourself
