Things You'll Need
New Sterling shower faucet stem
Make sure your replacement faucet stem is a Sterling brand and is similar to the old one that it is a one-handle or two-handle, depending on what you had before.
Sterling is a brand name for faucets that has been around for years. If your shower faucet begins to leak water from the handle or the water does not maintain a constant temperature, the shower stem may be worn out or damaged and most likely should be replaced. It is possible to install a Sterling shower faucet stem yourself with a few simple tools, which will save you money in the long run over hiring a professional. Sterling shower faucet stems can be purchased at a local hardware store.
Turn off the shower's water supply by turning the shutoff valve to the right. The water valve should be located near the shower or in the basement.
Remove the faucet's handle with an Allen wrench if it is a single-handle faucet. Twist the Allen wrench to loosen the screw in the bottom of the handle. If it is a two-handle faucet, use a flathead screwdriver to pop off the decorative cap that covers the screw and loosen the screw with the screwdriver. Pull off the screw.
Loosen the screw on the Sterling faucet stem with a screwdriver. Grab the old stem with a pair of adjustable pliers. You may need to twist the stem to get it out.
Slide the new Sterling stem into the opening of the faucet in the old one's place and push it in firmly. Tighten the screw holding the stem with a screwdriver.
Replace the handle on the faucet and tighten the screw that holds it with either an Allen wrench or screwdriver, depending on which one you used to remove it.
Turn the water back on and test the faucet stem to make sure it operates correctly.
