Having a dripping bathtub or shower faucet is a common household problem that can be annoying and costly. Not only does it waste water, but if left unresolved, it can lead to higher utility bills and potential water damage. Luckily, fixing a leaking bathtub and shower faucet is often a straightforward task you can do yourself with the right tools and a little know-how. This article will walk you through the steps to repair both a single-handled and two-handled dripping faucet and restore your bathroom functionality.
Diagnosing the Problem
Before diving into repairs, it's important to understand the type of faucet you have and what might be causing the drip. There are two types of faucets.
Single-handled faucets: a type of faucet that controls both the temperature and flow of water using a single lever or knob. Instead of having separate handles for hot and cold water, a single-handle faucet combines the two functions into one operating mechanism using a cartridge which is the main component. To get the temperature you want, you can combine hot and cold water and control the flow of water by shifting the handle.
Two-Handled Faucets: a type of faucet that has separate handles to control hot and cold water separately. Each handle controls the water flow and temperature from its respective supply line, allowing for precise control over the water mixture. Typically operating with compression or cartridge mechanisms.
Tools and Materials Required
Before you begin, it's essential to gather all the necessary tools and materials. Here's what you will need for the repair:
Adjustable wrench
Flathead and Phillips screwdrivers
Replacement faucet parts (depending on the type of faucet, such as a cartridge, valve, washer, or O-ring)
Plumber's tape (optional, for sealing threads)
Towel or cloth (to protect fixtures and catch any water)
Bucket or container (for catching water and preventing spills)
Allen wrench (if required, for some types of faucets)
Lubricant (silicone grease or plumber's grease, optional for smooth operation)
Preparation Steps
Proper preparation ensures a smoother repair process.
Turn Off the Water Supply: Locate the stop valve for your bathtub or shower, usually found under the sink or near the water heater in the basement and turn it off. If thereʼs no specific valve for the faucet where the problem is, then shut off the main water supply to your home.
Relieve Water Pressure: Open the faucet to release any residual water pressure from the pipes. This also helps drain any remaining water from the faucet, making the repair process cleaner.
Cover the Drain: Place a cloth or stopper over the drain to avoid losing small parts.
Gather Tools and Replacement Parts: You'll need screwdrivers, an Allen wrench, pliers, and potentially replacement cartridges, washers, or O-rings for the damaged component.
Fixing a Single-Handled bathtub or shower Faucet
In a single-handle faucets, the cartridge is the main component which contains ceramic discs, which slide against each other to control the flow and temperature of water. To fix the single-handle bathtub or shower faucet.
Step 1: Disassemble the Faucet
After turning off the water, it's time to take the faucet apart.
Take off the decorative cap from the handle (if applicable).
The screw holding the handle in place is sometimes covered with a decorative cap on some faucets. You should carefully remove the cap with a flathead screwdriver. The screw holding the handle in place will become visible as a result.
Remove the handle screw
Remove the screw holding the handle in place with a Phillips or flathead screwdriver, depending on the kind of screw. Remove the handle from the faucet base with care.
Take off the Escutcheon cover plate.
To reach the valve, you must remove any cover plate or escutcheon that may be attached to your faucet. Use a screwdriver or adjustable wrench to remove the plate.
Take out the cartridge or valve.
Use a wrench to unscrew the valve or cartridge, depending on whether your faucet is a cartridge or compression faucet. Gently remove the valve or cartridge, being cautious not to harm the other parts.
Step 2: Inspect and Identify the Problem
Now that the faucet has been disassembled, you can locate the source of the leak.
Examine the washer or cartridge.
Examine the washers on your faucet for wear, cracking, or brittleness. Check for mineral buildup or cracks on the cartridge in cartridge faucets.
Check for any damaged seals or O-rings.
Examine any rubber seals or O-rings inside the cartridge or valve. These parts are frequently to blame for leaks. Keep an eye out for wear indicators like cracks or distortion.
Compare Old Parts to New
Make sure the replacement part is the same size and kind as the damaged one by taking it to your neighborhood hardware or plumbing supply store.
Step 3: Replace Faulty Parts
It's time to install new parts now that you've determined what the problem is.
Install the New Washer, O-Ring, or Cartridge.
Replace the old cartridge, O-ring, or washer with the new one, depending on what was damaged. Apply a tiny bit of silicone grease or other lubrication if you're using an O-ring or rubber washer to guarantee a smooth fit and avoid early wear.
Reassemble the Faucet.
Put the faucet back together when the replacement parts have been installed. First, replace the cartridge or valve in the faucet body. After that, screw the cover plate or escutcheon back into position.
Reinstall the Handle.
Plug the handle back in on the faucet and tighten it using the screw you previously removed. Make sure everything is securely fastened, but don't tighten it too much since this could lead to damage.
Step 4: Test the Faucet
It's time to test your repair after the faucet has been put back together.
Switch the water supply on - Restart the water supply gradually. Verify that there are no leaks near the faucet and that the water flows correctly.
Look for any drips - Let the faucet run for a few minutes after turning it on. You have successfully repaired the faucet if it no longer drips. If the faucet still drips, though, there might be a problem with the replacement parts or the installation.
Fixing a Two-Handled bathtub or shower Faucet
Fixing a two-handled bathtub or shower faucet follows the same process as the single-handled faucet. But for the two-handled faucet, you have to know which handle the drip is coming from.
Step 1: Identify the leaking faucet
Determine if the leak is coming from the hot or cold side. One of the finest ways is to feel the temperature of the drip water.
If the drop is hot or warm, it is coming from the hot side, while cold water is coming from the cold side.
Turn off the hot or cold water supply gradually. Only try one at a time. Wait and see whether the drip appears. If the leakage continues after the first value has been switched off, the leak is on the other side.
Step 2: Disassemble the Faucet
Remove the decorative screws and caps: Using a flathead screwdriver, pry off the handles' ornamental caps. To remove the screws holding the handles in place, use a Phillips screwdriver.
Remove the handles: To reveal the faucet stems, carefully remove the handles.
Unscrew the faucet stems: Carefully loosen and extract the stems from the valve body using an adjustable wrench.
Step 3: Inspect and Replace Components
Check O-rings and washers: Look for signs of hardness, wear, or cracks in these rubber parts. If they are damaged, replace them.
Check valve seats: Use a flashlight to check for pitting or corrosion. Use a seat grinder to resurface the valve seats, or replace them if they are seriously damaged.
Inspect the faucet stem: Look for rust, cracks, or other damage. If required, swap out the stem.
Step 4: Reassemble the Faucet
Reinstall the faucet stems: Using an adjustable wrench, firmly tighten the stems into the valve body.
Reattach the screws and handles: Tighten the screws and align the handles correctly.
Replace decorative caps: To get a finished appearance, snap the caps back onto the handles.
Step 5: Testing the Faucet
Restart the water supply.
Check the faucet for leaks by running water through it.
To make sure everything is correctly aligned, tighten connections or check the internal components again if leaks continue
