AvatarByColleen Barnes Shower Hardware

Removing a Delta bathtub faucet may seem like a daunting task, especially if you’re not familiar with plumbing work. Whether you’re upgrading your bathroom fixtures, fixing a leak, or simply replacing a worn-out faucet, knowing how to properly remove your Delta bathtub faucet is an essential first step. With the right approach, tools, and a bit of patience, you can tackle this project confidently and avoid common pitfalls.

Understanding the basics of how your Delta faucet is installed and secured will help you navigate the removal process smoothly. Each faucet model may have its unique features, but the general principles remain consistent. By preparing yourself with the right knowledge, you can save time, prevent damage to your plumbing, and set the stage for a successful installation of a new fixture.

In the following sections, we’ll explore the key considerations and steps involved in removing a Delta bathtub faucet. Whether you’re a seasoned DIYer or a first-time homeowner, this guide will equip you with the insights you need to approach the task methodically and effectively.

Removing the Faucet Handle

Begin by locating the set screw that secures the faucet handle to the valve stem. This screw is usually hidden under a decorative cap on the handle face. Gently pry off this cap with a flathead screwdriver or a fingernail to expose the screw.

Using the appropriate Allen wrench or screwdriver, loosen and remove the set screw. Once the screw is out, carefully pull the handle straight off the valve stem. If the handle is stuck due to mineral buildup or corrosion, apply a penetrating lubricant and allow it to sit for a few minutes before trying again. Avoid using excessive force to prevent damaging the handle or the stem.

Detaching the Escutcheon Plate and Spout

After removing the handle, focus on the escutcheon plate (the decorative plate that covers the valve hole). This plate is typically secured with screws or may be held in place by a threaded collar.

  • If screws are present, remove them with a screwdriver and gently pull the plate away from the wall.
  • For threaded collars, turn the escutcheon counterclockwise to unscrew it from the valve body.

Next, remove the spout. Delta bathtub faucets generally have one of two spout types: slip-on or threaded.

  • Slip-on Spout: Look for a set screw underneath the spout near the wall. Loosen it with an Allen wrench and pull the spout off.
  • Threaded Spout: Rotate the spout counterclockwise to unscrew it from the pipe nipple. You may need to use a strap wrench to avoid scratching the finish.

If the spout is stuck, applying penetrating oil and gently tapping with a rubber mallet can help loosen it.

Disconnecting the Valve Body

With the handle, escutcheon plate, and spout removed, the valve body should now be accessible. To disconnect it:

  • Turn off the water supply at the main shutoff valve to prevent leaks.
  • Use a wrench to disconnect the supply lines from the valve.
  • Remove any mounting brackets or screws securing the valve body to the wall framing.
  • Gently pull the valve body out for replacement or repair.

Take care to note the orientation and position of the valve for reinstallation. If the valve is soldered or glued to the supply lines, cutting tools or additional plumbing expertise may be necessary.

Common Tools Required for Removal

The following tools are typically required to remove a Delta bathtub faucet:

  • Flathead screwdriver (to remove decorative caps)
  • Allen wrench set (for set screws)
  • Phillips screwdriver (for escutcheon screws)
  • Adjustable wrench or basin wrench (for supply lines)
  • Strap wrench (to avoid damaging spout finish)
  • Penetrating oil (to loosen stuck parts)
  • Rubber mallet (for gentle tapping)
Tool Purpose
Flathead Screwdriver Removing decorative caps
Allen Wrench Loosening set screws on handles and spouts
Phillips Screwdriver Removing escutcheon plate screws
Adjustable Wrench Disconnecting supply lines
Strap Wrench Unscrewing threaded spouts without damage
Penetrating Oil Loosening corroded or stuck components
Rubber Mallet Applying gentle force without damage

Preparing to Remove the Delta Bathtub Faucet

Before beginning the removal process, ensure you have all necessary tools and have taken safety precautions to prevent damage and injury. Proper preparation streamlines the process and protects the plumbing system.

  • Tools Needed:
    • Adjustable wrench or basin wrench
    • Allen wrench (typically 3/32″ or 1/8″)
    • Screwdriver (Phillips and flathead)
    • Pliers
    • Utility knife or putty knife
    • Bucket or towel to catch water drips
    • Penetrating oil (optional, for stuck parts)
  • Safety and Preparation Steps:
    • Turn off the main water supply or the local valve supplying water to the bathtub.
    • Open the faucet to drain residual water and relieve pressure.
    • Cover the tub drain with a rag or stopper to prevent small parts from falling in.
    • Lay down towels to protect the tub surface from scratches and catch water spills.

Removing the Faucet Handle and Trim

Delta bathtub faucets typically have a handle secured by a set screw or a decorative cap. Removing these components carefully avoids damage to the handle and underlying mechanisms.

Follow these steps to remove the handle and trim:

  1. Locate the Handle Set Screw:
    Look for a small screw on the side or underside of the handle. It is often concealed under a decorative cap.
  2. Remove the Decorative Cap:
    Use a flathead screwdriver or utility knife to gently pry off the cap, exposing the set screw.
  3. Unscrew the Set Screw:
    Use the appropriate Allen wrench to loosen and remove the set screw completely.
  4. Pull Off the Handle:
    Gently wiggle and pull the handle away from the valve stem. If it is stuck, apply penetrating oil and wait a few minutes before trying again.
  5. Remove the Trim Plate:
    Unscrew any screws securing the escutcheon (trim plate) using a screwdriver. Carefully pull the plate off to expose the valve body.

Detaching the Spout

Delta bathtub spouts can be attached via a threaded connection or a slip-on method secured by a set screw. Identifying the type of attachment is crucial for proper removal.

Attachment Type Identification Removal Method
Threaded Spout Spout rotates; no visible set screw. Turn the spout counterclockwise by hand or with a strap wrench to unscrew.
Slip-On Spout Has a small set screw underneath or on the side near the wall. Loosen the set screw with an Allen wrench, then pull the spout straight off.

When removing the spout:

  • Ensure the water supply is off and the valve is open to relieve pressure.
  • If the spout is stuck, apply penetrating oil on the joint and allow it to soak.
  • Use a strap wrench to avoid damaging the finish when unscrewing.
  • Inspect the plumbing connection for corrosion or damage once removed.

Removing the Cartridge Valve

The cartridge valve controls the flow and temperature of the water in a Delta faucet. Removing it requires careful handling to avoid damage to the valve body.

Steps to remove the cartridge valve:

  1. Remove the Handle and Trim:
    Complete the prior steps to expose the cartridge.
  2. Unscrew the Cartridge Retaining Nut:
    Use an adjustable wrench to loosen and remove the retaining nut securing the cartridge.
  3. Extract the Cartridge:
    Grasp the cartridge firmly with pliers or a cartridge puller tool and pull it straight out. Avoid twisting, which can damage the valve body.
  4. Inspect and Clean:
    Check the cartridge and valve body for mineral buildup or damage. Clean the valve body with vinegar or a commercial cleaner if needed.

Important: Take note of the cartridge orientation to ensure proper reinstallation or replacement.

Tips for Avoiding Common Issues During Removal

  • Use Proper Tools: Using the correct size Allen wrench and screwdrivers prevents stripping fasteners.
  • Apply Penetrating Oil: This helps loosen corroded or stuck parts without forcing them.
  • Protect Fixtures: Avoid metal tools directly contacting polished surfaces; use cloth or rubber grips to prevent scratches.
  • Document Assembly: Take photos or notes during disassembly to aid in accurate reassembly.
  • Work Gently: Excessive force can damage plumbing connections or the valve body, leading to costly repairs.
