How to Repair an Old Bathtub Faucet

As a homeowner, you will inevitably encounter various household repairs, and addressing a leaky or malfunctioning bathtub faucet is a relatively common task. While it may seem daunting, repairing an old bathtub faucet is a manageable project that can be completed with the right tools and a systematic approach. This article will guide you through the essential aspects of how to repair an old bathtub faucet, providing step-by-step instructions to restore your faucet to proper working condition.

Step 1: Identifying the Faucet Type

Before commencing any repairs, it is crucial to determine the type of bathtub faucet you have. Two main types of bathtub faucets exist: compression faucets and cartridge faucets. Compression faucets feature a washer that creates a seal against the valve seat to control water flow, while cartridge faucets utilize a single removable cartridge to regulate water flow and temperature.

Step 2: Gathering Tools and Replacement Parts

Once you have identified the faucet type, gather the necessary tools and replacement parts for the repair. For compression faucets, you will need adjustable wrenches, a screwdriver, and new washer(s). For cartridge faucets, you will require a cartridge puller or wrench specifically designed for your faucet model and a replacement cartridge.

Step 3: Disassembling the Faucet

Begin by turning off the water supply to the faucet using the shut-off valves located beneath the bathroom sink. Next, remove the faucet handle by unscrewing the handle screw with a screwdriver. For compression faucets, use adjustable wrenches to loosen the packing nut and remove the stem assembly. For cartridge faucets, insert the cartridge puller into the cartridge slot and pull out the old cartridge.

Step 4: Replacing Washer or Cartridge

Inspect the removed washer or cartridge for any visible damage or wear. Replace the old washer with a new one of the same size and type. For cartridge faucets, simply insert the new cartridge into the faucet body and align it properly before tightening the retaining nut.

Step 5: Reassembling the Faucet

Tighten the packing nut securely for compression faucets, ensuring no leaks occur. Reattach the stem assembly and handle. For cartridge faucets, tighten the retaining nut to the manufacturer's specifications. Finally, reattach the faucet handle and tighten the handle screw.

Step 6: Testing the Faucet

Turn on the water supply and check for leaks. If no leaks are present, your faucet is successfully repaired. Run the faucet for a few minutes to ensure proper water flow and temperature control.

Additional Tips

Here are some additional tips to help you repair your old bathtub faucet:

If you encounter significant difficulty removing the faucet handle or cartridge, apply penetrating oil to the threads and allow it to soak for a few minutes before attempting removal.
Use caution when tightening the packing nut, as overtightening can damage the faucet.
If you are unsure about any aspect of the repair, it is recommended to consult a professional plumber.
