I just installed a new bathtub faucet. After installing, I noticed a single drop a few hours after it had been turned off. I put a bowl to see, and in the morning there was maybe a teaspoon of water. Trying to make sure it is/is not faulty before either replacing or putting tub skirt back on. I turned off the water access and over night there was maybe a single drop, faucet is wet to the touch but no noticeable dripping. Is this normal for water to continue out of the faucet?

When you had everything apart did you turn the water on for a minute to flush out any trash you might have dislodged If not then shut the water off and open up the faucet. Remove the cartridges and flush the lines, Check and clear the cartridge inlets. Reassemble and test. Good luck, Tom
