Removing Delta Monitor Bathtub Faucet Handle: A Step-By-Step Guide

Removing the handle from a Delta Monitor bathtub faucet can be a challenging task, as evident by the numerous forum posts and discussions on the topic. The process may vary depending on the specific model of the faucet, but there are some general steps and tips that can be followed. One common issue is a stripped or stuck set screw, which can be addressed by using the appropriate screwdriver or drill, applying penetrating oil, or using a screw extractor. It is important to note that excessive force should be avoided to prevent damage to the faucet. Additionally, covering the bathtub drain with a cloth is recommended to prevent small parts from falling into it. In some cases, it may be necessary to replace the handle or the entire faucet if the set screw cannot be removed or if other issues arise.

Removing a stripped set screw

Understand the Cause:

Before attempting any repairs, it's important to understand why the set screw is stripped in the first place. In most cases, it's due to corrosion or rust buildup over time. This results in the screw becoming stuck and difficult to turn.

Apply Penetrating Oil:

Start by applying a penetrating oil, such as WD-40, CLR, or PB Blaster, to the screw. This will help loosen any corrosion or rust that is holding the screw in place. Let the oil sit for a while, following the product instructions, to allow it to penetrate effectively.

Attempt to Turn the Screw:

After applying the penetrating oil, try using the appropriate screwdriver or Allen key to turn the screw counterclockwise. If the screw is severely stripped, you may need to use a slightly larger Allen key and gently tap it into the screw with a hammer to gain some grip. Be careful not to apply too much force, as you don't want to damage the screw head or the surrounding handle.

Use a Screw Extractor:

If turning the screw is unsuccessful, the next step is to use a screw extractor. These tools are designed to remove stripped or broken screws. Choose an extractor that fits snugly into the screw head, and use a tap handle or adjustable wrench to turn it counterclockwise. This method should allow you to grip and remove the screw without causing further damage.

Drill Out the Screw:

If the screw still won't budge, drilling it out may be your last resort. This method will likely ruin the screw and possibly the faucet handle, so proceed with caution. Use a drill bit that is slightly smaller than the screw diameter to avoid drilling into the surrounding parts. Drill slowly and carefully to avoid slipping and causing additional damage. Once the screw is drilled out, you may need to replace the handle to restore the faucet's appearance.

Handle Removal:

After successfully removing the stripped set screw, focus on removing the handle. In some cases, the handle may be stuck due to corrosion or calcium buildup. Try gently tapping the handle with a mallet or using a flat-head screwdriver to pry it loose. If necessary, apply heat to the top of the handle where the spindle is located, being cautious not to overheat and damage the plastic parts.

Remember to work carefully and patiently when dealing with stripped screws and stuck faucet handles. It's always a good idea to have replacement parts on hand, such as a new handle or cartridge, in case any damage occurs during the removal process.

Using a handle-pulling tool

If you are struggling to remove the handle from your Delta Monitor bathtub faucet, you may need to use a handle-pulling tool. This is a good option if the set screw is rusted in place or has been stripped.

You can purchase a handle-pulling tool from a home store. Once you have the tool, follow these steps:

• Place the handle-pulling tool around the handle, ensuring a secure fit.
• Slowly and firmly, begin to pull on the tool to create tension.
• Continue to increase the tension until the handle pops off.

It is important to be careful when using a handle-pulling tool, as applying too much force can damage the faucet or the surrounding area. If you are concerned about damage, you may want to consider other methods of removing the handle or consult with a professional.

Additionally, if the set screw is stripped, you can try drilling it out with a cobalt drill or a titanium drill bit. This will require some force, but be careful not to damage the handle or the underlying cartridge.

If the handle is still not coming off, you can try applying heat to the top of the handle where the spindle is located. A hair dryer or similar tool can be used for this purpose. Alternatively, gently tapping the handle with a rubber mallet may help loosen it.

In some cases, you may need to cut the handle off with a hacksaw. This should be a last resort, as it will require replacing the entire faucet.

Drilling out a set screw

Step 1: Understand the Challenges

Before you begin, it's important to know that drilling out a set screw can be difficult. The screw might be tightly fastened, or there could be corrosion or rust holding it in place. In some cases, the screw may be made of a very hard material that can dull or break regular drill bits. This is a common issue with set screws, as they are often made from hardened steel.

Step 2: Gather the Right Tools

To drill out a set screw, you will need a suitable drill and appropriate drill bits. A power drill or drill press can be used, but it's crucial to secure the drill firmly in place, such as by clamping it to a table. The type of drill bit you'll need depends on the material of the set screw. For example, if the set screw is made of hardened steel, you may require a solid carbide drill bit or a carbide-tipped masonry bit. In some cases, you may need to use a drill bit with a specific type of point, such as a flat point.

Step 3: Prepare the Screw

Before drilling, it's a good idea to apply penetrating oil to the set screw and let it sit for a while. This can help loosen any corrosion or rust that is holding the screw in place. If the screw is very tight, you may also need to apply heat to the area to help loosen it. However, be cautious when applying heat, especially if there are plastic components nearby that could melt.

Step 4: Start Drilling

Once your drill is securely mounted and you have the appropriate drill bit, you can begin drilling. Brace the set screw firmly and apply the drill bit to the centre of the screw head. Start drilling slowly and with moderate speed, as too much speed can generate heat and damage the drill bit. Use a steady pressure and continue drilling until you have completely drilled through the set screw.

Step 5: Remove the Screw

After drilling through the set screw, you may be able to simply unscrew it from the hole. If the screw is badly damaged or broken, you might need to use a tool like an easy-out to remove it. Alternatively, you can try cutting over to the side of the screw at two points to split it into halves and then pick out the pieces with a small tool like a dental pick.

Step 6: Finish the Job

Once the set screw is removed, you may need to retap the hole to clean up the threads. This will ensure that you can properly secure a new set screw in place. After retapping, apply a small amount of thread-locking fluid or thread sealant to the new set screw before installing it. This will help prevent the new screw from becoming seized in the future.

Removing a rubber plug

Step 1: Turn Off the Water Supply

Before starting any work on your bathtub faucet, it is crucial to turn off the water supply to the house. This will prevent any leaks or flooding during the repair process. Locate the main building shut-off valve, typically found in the basement or mechanical room, and turn off the water. Then, open the bathtub faucet to drain any trapped water in the pipes.

Step 2: Prepare the Work Area

Place a towel or a drop cloth in the bottom of the tub to catch any small parts and prevent them from falling into the drain. This will also protect the tub's surface from scratches or damage.

Step 3: Remove the Handle

The process of removing the handle will depend on whether your Delta Monitor faucet has a set screw or not.

Delta Monitor Faucet with a Set Screw:

• Identify the set screw at the base of the handle. It is usually covered by a plastic cap or index, which you can pry off gently using a flat-head screwdriver.
• Once the set screw is exposed, use an Allen wrench or the appropriate screwdriver to loosen and remove it.
• Pull the handle off the faucet stem. If it is stuck, try using a faucet handle puller, available at most hardware stores.

Delta Monitor Faucet without a Set Screw:

If your faucet handle does not have a set screw, try twisting the handle counterclockwise to remove it. You may need to use a handle puller for extra leverage.

Step 4: Remove the Rubber Plug

The rubber plug, also known as the cartridge, is located inside the faucet handle. It regulates water flow and temperature. To remove it:

• Use a pass-through socket wrench to grip the hex nut at the base of the faucet stem.
• Turn the socket wrench counterclockwise to loosen the hex nut.
• Once loosened, pull out the rubber plug/cartridge by hand.

Tips and Troubleshooting:

• If the set screw is stripped or stuck, you may need to drill it out. This will likely require replacing the handle.
• If the handle is stuck even after removing the set screw, try using penetrating oil like WD-40 or vinegar, and let it sit for a while before trying again.
• For stubborn corrosion, use a rust softener like CLR and let it sit for about 20 minutes before attempting to remove the screw.
• If all else fails, consider cutting the handle off with a hacksaw, but be careful not to damage the underlying parts.

Remember to keep your work area well-organized and take your time during the removal process. Always put pressure on the handle and rubber plug evenly to avoid damaging the faucet body or surrounding fixtures.

Using a flat-head screwdriver

To remove the handle from a Delta Monitor bathtub faucet using a flat-head screwdriver, follow these steps:

First, place a washcloth or towel over the bathtub drain to prevent the small handle-securing screw from accidentally falling down the drain.

Next, identify the type of handle you have. If you have a lever-type handle, feel or look under the curve of the handle for a small rubber plug. This plug is slightly raised and can be removed by pulling it out with your fingers or a pair of needle-nose pliers. If you do not see a plug, look for the seam between the top and body of the handle, as Delta uses a cover on knob-type faucets and some lever-type faucet handles.

If your handle has a rubber plug, remove it with your fingers or needle-nose pliers, then use an Allen wrench or Phillips-head screwdriver to remove the screw, depending on the type of screw head. If your handle has a cover, insert a small flat-head screwdriver into the seam between the top and body of the handle and gently pry the cover away.

Once the cover or plug is removed, you will expose the centre-located securing screw. Turn this screw counterclockwise with a Phillips-head screwdriver and pull the handle straight off the cartridge.

If your handle does not have a plug or cover, you may need to slowly and forcefully turn the faucet handle past its resistance point with the faucet in the on and off positions. Alternatively, there may be a retaining nut on the underside of the sink counter that needs to be loosened.

If you encounter a stripped screw, you may need to drill it out with the next size up drill bit.
