Dealing with a Shower Diverter Pin Came Out[Quick Solutions]

Nothing would be more annoying than when you have just pulled up your diverter pin to engage the shower and it has become dislodged from its setting or fallen out completely. Don’t worry, the issue is very common to most of the users. 

But what would be the reason if your shower diverter pin came out? 

Over time the internal rubber gasket and diverter assembly become loose and release the pin even with minimal force. In most cases, a damaged or worn-out O-ring is the culprit.

The good news is this can often be repaired by simply replacing the O-ring or gasket inside the diverter assembly. Take apart the diverter, remove the old ring, lubricate, and properly install a new one, then reassemble. Test for smooth operation and no leaks.

Read our complete step-by-step instructions on how to easily fix a shower diverter pin that fell out with a few tools and replacement parts!

Quick Overview Of The Shower Diverter Mechanism: What’s The Role Of the Diverter Pin here?

A shower diverter is the most common plumbing device that allows you to switch the flow of water between the tub faucet and the shower head. All its functions are performed through the equipped pin or knob that controls the water flow by blocking from one outlet while allowing it to a different outlet.

• Mainly when you push down or turn the diverter pin one way, it blocks the opening to the shower outlet and routes all water directly through the tub faucet into the bathtub.
• Conversely, when you pull up on the pin, it seals off the tub opening and allows water pressure to force upward to the showerhead.

Common Reasons For Shower Diverter Pin Coming Out

Before heading over the repairing processes, let’s have a short glimpse at some primary reasons why your shower diverter pin may come out:

1. Improper initial installation:

Have you just installed a new diverter for your bathtub spout and that has fallen out? If so, the higher possibility is the diverter wasn’t installed correctly. 

For instance, you might be using an incorrect replacement part for your tub spout. 

Either the diverter pin is too small or too large, causing it to slip out. It is the proper manufacturer replacement pin for a secure connection. 

2. Missing or Loose Rubber Washer

Almost all the diverter pins are equipped with a short rubber gasket inside that holds the pin in place. In case the rubber is loosened or not correctly secured in place, it fails to hold the pin, causing it to fall down. 

In most cases, a missed rubber washer during installation or any of the plumbing work leads to this issue. 

3. Damage From Force:

The diverter valve is designed to be used very delicately. Hitting or forcing the diverter handle can knock the pin loose and make it unstable at its connection point. 

4. Excessive Water Pressure:

Water pressure has a big impact on the overall operation of the tub spout including the diverter function. If there is too much water pressure from the back, it is not quite impossible that it will wear out a tub spout diverter. 

High water pressure puts additional stress on the diverter valve, making it fall out if it’s not properly secured.

Repairing The Shower Diverter Pin That Has Fallen Out? Learn Easy Ways To Fix!

If your shower diverter has fallen out, reinstalling it is the cheapest method to deal with the issue. But here fret not even if you are completely new to this plumbing work.

Here I will share with you the easiest methods to re-insert the diverter pin back in place. So, let’s get to the point!

Step #1: Turn Off The Water Supply

Start by turning off the water supply to your bathroom fixture. Locate the shut-off valves at the main line and turn them clockwise all the way to stop the flow.

Step #2: Seal Off The Drain

Now take a rag or wood block over the drain to seal it off. It would keep parts from falling into the drain and prevent potential clogs.

Step #3: Inspect The Fell Out Diverter Pin

Before inserting the pin, it’s important to closely inspect it to determine if it is still in good condition and suitable for reuse. For instance, here are a few things that you should check:

• Examine the pin for any visible damage like cracks, chips, or excessive wear and tear. Even small defects can prevent the pin from seating securely.
• Look to see if the pin is bent or distorted in any way. If really that is so, you will need to replace it.
• Ensure any o-rings or seals on the pin are still present and in good condition. Missing or damaged seals can cause leaks.
• Clean off any debris, residue, or corrosion from the pin surface before reusing.

Step #4: Do You Need To Remove The Tub Spout?

Well, it is not necessary to disassemble the tub spout in order to replace the fallen-out single-lever diverter pin.  Diverter pins are designed to be removed and installed through the front without complete spout removal. 

But still, to get a better view of the internal parts, you can remove the tub spout from the connection. To do so:

• Simply scrape off the chalk around the tub spout with a putty knife or razor. Or remove the little rubber seal securing the tub spout in connection. 
• Check for any set screws underneath the spout.  unscrew them using an Allen wrench or small screwdriver if present.
• Now hold the tub spout in hand and turn it counterclockwise until it comes off the brass adapter.

Step #5: Re-attach The Diverter Pin

Now start attaching the diverter pin. First, take your diverter pin and put it inside the hole of the tub spout. It will go down until the upper pole comes to the mouth.

Anyway, in the next step, take your white plastic part of the diverter and inspect it for any damages. For instance, make sure the rubber gasket is secured in place. 

Now slide the plastic part with the rubber gasket on the opposite side between the notches of the diverter gate. Make the groove of the diverter pin rest in the plastic hook.

See the picture below for any confusion.

Step #6: Secure & Test the Diverter Pin

When done, check and ensure that the diverter pin is aligning with its white plastic assembly.  Now test pin by push and pull it out. It should in and out with the inner plastic conveniently and efficiently. 

Step #7: Insert The Tub Spout

If you have removed the tub spout, inspect the water pipe thread for any calcium or rust buildup before inserting the spout. If so, clean it thoroughly with vinegar or any descaler solution. 

When done, slide the tub spout in until the pipe itself meets with the rubber gasket. Make sure the tub spout is aligned with the pipe correctly.  

Now take your Allen wrench and secure the lower screw back in place.  You are done! Enjoy your shower! 

How To Fix Fallen Out Push Pin Shower Diverter?

If you have a tub with a spout with a push button diverter pin, then replacing methods of the pin back in connection would be different than the above one. It uses a spring-loaded push button on the underside of the spout that is pressed to divert water up to the shower head.

Anyway, here are step-by-step instructions to fix a push-pin tub diverter (Delta Brand): 

Step #1: Start by turning off the water supply to your bathroom fixtures. Locate the main shut-off valves and turn them to the off position. 

Step #2: Then pull out the shower handle from the connection. For instance, you may need to pry off the plastic decorative piece from the handle and remove the set screw. 

Step #3: Remove the screws from the escutcheon plate and pull it out. Now you will see the shower valve where the diverter valve is connected.

Step #4: Now use a stem wrench or pliers and take out the existing part of the diverter valve. 

Step #5: Inspect the diverter valve hole for any hard mineral or rust build-up. If so, use needle nose pliers and remove any chunk piece of debris. 

Step #6: Now insert the plastic piece of the diverter valve inside the hole and tighten it down as much as possible. Use a socket wrench for a better grip.

Step #7: When done, assemble the escutcheon plate and shower handle back in place and test your shower diverter. 

In case you have a Kohler shower push button diverter valve, repair it just by the following:

• First, take the push stop first and thread it back in the hole.
• Now use a small Allen wrench and secure the set screws with a small Allen wrench, making sure they are tightened enough. 
• Finally, insert the cover over the push stop and screwed it as well. 

Major Reasons Why My Shower Diverter Pin Keeps Coming Out [With Easy Troubleshooting Tips]

While dealing with the same case, I found my shower tub spout diverter pin stuck and fell down when I tried to toggle it back and forth with force. Then I inserted the pin back in connection following the exact step discussed above. 

Unfortunately, after turning on the water supply, I pulled the pin and it again came off. If your diverter pin keeps falling down again and again, here are some major factors that you should concentrate on: 

i) Mineral Buildup:

If you are living in a hard water area, it would be a common phenomenon for you to frequently build lime scale in the plumbing fixtures. Hard water mineral content like calcium or magnesium is responsible for it which passes through the diverter and adheres to rubber washers and gaskets.

At a certain time, it leaves scale behind when the water evaporates. If that is so,  Hard water deposits in the tub spout and around the pin will prevent it from seating securely. 

How To Fix:

Descaling the hard mineral from the metal parts of the tub spout is the only solution to deal with the issue. Even it’s not something rocket science. 

Just remove the tub spout from the connection and submerge it in a vinegar solution for a few hours. After that, scrub the loose minerals with a brush and rinse them away. 

You can even use a suitable scaler or home remedy like lemon juice as well for cleaning purposes. 

ii) Corrosion

After a long time, the adhered rust, and calcium deposits start wearing away or deteriorating the metal components of the tub spout, leading to corrosion. Pitting and corrosion roughen the inside bore of the spout, making it unstable to hold the pin. 

How To Fix:

In case of a corroded or rusty tub spout, you will need to replace it as a whole. This will provide undamaged threads, sealing surfaces, and a smooth pinhole for a secure fit.

If somehow, it is not feasible right that moment, thoroughly clean out the pinhole and threads using a wire brush or steel wool. Use a descaling solution for a better result. 

iii) Corroded or Damaged Washer

The rubber washer inside the white plastic rubber plays a big role in holding the pin in place. In case the pin comes out again and again, the best possibility it is damaged or worn out. 

How To Fix:

Inspect closely the rubber washer for signs of corrosion, cracking, and deformation. Replace the damaged rubber gasket with a new one and secure it back in place. 

Tips: You can lightly coat the washer and sealing surfaces with a lubricating oil during reassembly. This will improve its moving function. It will also provide a barrier against moisture and early corrosion. So don’t skip this part! 

iv) Cracked Tub Spout

If still you are dealing with the malfunctioning shower diverter valve that keeps falling down even after once you set it up, check whether the tub spout is in good condition. 

Yes, you got it right! If the tub spout is cracked especially in the opening where the diverter valve is installed, it will fail to hold the pin. 

How To Fix:

Examine your tub spout for any hairline cracks or fracture lines. If so, remove it and install a new one. Don’t worry, it’s not too expensive.  

Tub spouts with diverter pins can cost between $27 and $180, depending on the brand and model.
