Hi, I'm Tom from Signature Hardware. If your bathtub faucet is leaking or the handles have stopped turning properly, it could be caused by a buildup of sediment and hard water deposits in the faucet cartridge.
In this video, we're going to show you how to clean the cartridge yourself, and get your faucet working smoothly again.

We’re going to need a couple of tools for the job; an open-ended wrench, maybe an Allen wrench, a screw driver, a plastic bowl, a bucket of clean water, a towel, and maybe even an extra set of hands.

First, you'll need to shut off the water supply to the tub. Have your extra set of hands turn off the main water supply to the house, usually found in the basement or lowest level of your home.

Then, turn on both your hot and cold water taps to drain any excess water from the faucet. Once that's done, turn the taps back to the “off” position.
At this point, it’s a good idea to close or block the drain. This will keep any small parts from falling into it.

Now we're going to remove the faucet handles. Faucet handles can differ by model, but they're typically attached by a screw.
If there's a decorative cap or button on the handle, you'll want to take that off first to get to the screw. If there's an escutcheon or other trim, remove that as well.
Now, loosen the cartridge assembly and remove it.

Your faucet cartridge may look different than the one we have here, but the steps for cleaning them are essentially the same.

Place a plastic bowl upside down over the faucet hole to direct water spray towards the drain. Have your extra set of hands turn on the water supply while you hold the bowl and let the water run for 3 or 4 seconds. This will flush out any debris trapped in the faucet or in the water line.

Now we’re going to rinse out the cartridges, placing them individually in the bucket of clean water. Open and close the cartridges by twisting the stem.
You may have to place the handle back on temporarily to move them.

Now reinsert the cartridges and reassemble the handles. It’s important to not to over-tighten the cartridge assembly. Stop when you feel resistance, otherwise you could damage the faucet.

If your faucet handles are working in reverse, you've probably placed the cartridges on the wrong sides. Simply take them back out and switch them.
Now reopen the water main and slowly turn on your taps. Check for any leaks and make sure the water runs smoothly.
