Understanding why your tub faucet leaks helps you fix it right the first time. Most leaks come from worn-out parts inside the faucet body. Worn washers and O-rings are the top culprits. These rubber seals create a watertight barrier when you turn off the water. After years of use, they crack, flatten, or tear. Water then seeps through and creates that steady drip. Corroded valve seats cause leaking tub faucet problems too. The valve seat connects the faucet to the spout. Mineral deposits from hard water build up here over time. This buildup prevents a tight seal and lets water through. Loose parts make your bathtub faucet drip even when everything looks fine. The packing nut around the stem can loosen from regular use. Temperature changes also cause metal parts to expand and contract, which loosens connections. Wrong washer size creates gaps where water escapes. If someone replaced parts before but used the wrong size, your tub faucet leak will continue no matter how tight you turn the handle. High water pressure stresses faucet components and causes premature wear. Pressure above 80 PSI pushes against seals constantly and makes them fail faster.
