How to repair a leaky shower faucet valve gas leak los angeles california


A shower valve that’s operated by two faucet handles—one hot and one cold—is typically a compression faucet, as discussed in the article How a Compression Faucet Works. Leaks in a compression faucet generally occur when a rubber seal or washer wears out over time, allowing water to seep between movable metal parts. Fixing a compression shower faucet involves disassembling the unit and replacing the defective washers and seals. It’s important to shut off the water supply to the shower, and to protect the surface of the tub or shower floor and cover the drain. Buy a faucet washer kit so you’ll have the necessary replacement O-rings and washers on hand.

First, feel the water leaking from the tub spout or shower head. If it’s warm, you know that the leak is coming from the hot-water valve. If the water has been dripping for a while and it is cold, the leak is probably coming from the cold-water valve.

1 Start by removing the faucet handle. Methods for doing this will depend upon the faucet’s design. Older or simply-designed faucets often have an exposed screw front and center or a locking screw in the side. Newer and more decorative models of faucets hide the screw beneath a cover cap. With these, you need to pry off the cover cap to expose the screw. If your faucet handle is the type with a cover cap and there is no obvious method of removal, use a very thin screwdriver or pocketknife to pry the cap off. Be careful not to scratch the finish or damage the material.

2 Once you’ve removed the cover cap, use a screwdriver to unscrew the locking screw, turning it counterclockwise. Remove it and set it aside. Then wiggle and pull on the handle to extract it from the faucet body. This can be difficult to do. You can buy a faucet puller, or improvise with a screwdriver as shown in this helpful video:

3 After removing the handle, remove the trim and the sleeve that fits over the faucet stem. You’ll need a plumber’s deep socket, as shown in the video, to extract the faucet stem from the valve body (you can buy an inexpensive set online). Fit it over the stem’s hex nut and turn it counterclockwise to unscrew the assembly. At first, you may need to apply significant force to break it free. Unscrew the faucet stem and pull it out of the valve body.

5 Then reverse the procedures to replace the faucet stem in the valve body. Before you put it in, lubricate the threads with plumber’s grease. Tighten it in the valve body. Temporarily put the handle back on, turn on the water supply, and test the valve. Then finish reassembly. Finally, seal the trim to the wall with tub caulk. How to Fix a Leaky Delta Shower Faucet

If your shower has a leaky Delta shower faucet, here is how to stop the leak. Before beginning, please read the information titled “Advice for Fixing Leaky Shower Faucets” above. Shut off the water supply to the shower and protect the surface of the tub or shower floor. Also cover the drain so you don’t accidentally drop small parts down it. Buy a Delta replacement cartridge so you’ll have the necessary replacement on hand. Here’s a video that shows this process:

5 Then insert the new cartridge. Note that one side of the cartridge is marked “Hot” and should be positioned on the hot water (normally left) side. Push it firmly in place. If necessary, adjust the rotational limit stop, according to the manufacturer’s directions that come with the replacement cartridge.

6 Put the brass bonnet back on the valve and turn it clockwise to tighten it. Be sure the threads grip properly. Hand-tighten, and then use locking jaw pliers to snug it down. Clean the wall where the escutcheon plate goes, and then put the outer sleeve back on the cartridge and push it into place. Replace the escutcheon plate and handle.

As when working on other types of shower valves, start by shutting off the water supply and protecting the tub and drain with rags. Ideally, your shower plumbing will have a local water supply valve that you can shut off (similar to the valve under a sink) that is accessible through a removable panel. In most cases, there isn’t one of these, so you’ll need to shut off the main valve for the entire house.

Open a nearby faucet to empty the shower pipes. Before beginning, please read the information titled “Advice for Fixing Leaky Shower Faucets” above. If your defective shower valve is made by Price Pfister, you’ll be happy to know that they stand behind their products with a strong warranty. If you can prove that you bought their valve after 1997, they will send you free parts. It’s definitely worth a call to their 800 number at 1-800-732-8238. You can also buy a replacement valve on Amazon.

2 Next, unscrew the threaded sleeve, turning it counterclockwise, and remove it from the escutcheon trim plate. If the escutcheon trim is caulked to the wall, use a sharp knife to cut the seal. Be careful not to scratch the surfaces. Remove the plate from the wall.

3 To remove the cartridge, unscrew the four screws that hold the dogged-eared mounting flange. Again, turn them counterclockwise to remove them. Reach in and pull the plastic cartridge out of the valve. Be sure the rubber O-rings come out with the cartridge.

5 Be sure the rubber gasket will seal properly. Position it so the orientation is properly aligned. Use the metal ring and four screws to secure it. When it’s tight, turn the water supply back on and check for leaks. If you don’t discover any leaks, caulk around the perimeter of the trim and then replace the escutcheon trim and the handle. Here is a really helpful video that shows this process.

3 A white plastic nut-like tool should be packaged with the new cartridge. Slip this plastic nut tool over the shaft so it interlocks with the cartridge. Then turn it back and forth with pliers to release the cartridge from the valve body. Remove the nut, and then use pliers to grip the stem of the cartridge and pull it straight out of the valve body.

4 Push the new replacement cartridge straight into the valve body until it seats. Slip the plastic nut tool onto the cartridge and orient the cartridge so that its ears are at the top and bottom of the valve body. Slide the U-shaped retainer clip back into the valve body until it snaps into place. If the retainer clip doesn’t snap into place properly, the cartridge is not seated correctly in the valve body—readjust it with the plastic nut tool.

5 Now turn the water supply back on. Temporarily mount the faucet knob on the shaft. Holding a bucket under the shower head, turn on the hot water to make sure the hot water works. If the water doesn’t get hot, you’ll need to readjust the cartridge with the plastic nut tool and check again until you get hot water.
