There are several bathtub drain stopper types, each with a distinct function. Among the various bathtub drain stopper types, pop-up drain stoppers are also used in various drainage systems. A simple mechanical device closes off a sink or bathtub drain by raising and lowering the stopper using links and levers. A pop-up drain stopper can seem complicated but simple to repair. Taking a bath when water drains slowly due to a leaking pop-up stopper isn’t amusing. This guide will explain the type of bathtub drain stopper removal, such as pop-up drain stopper. All can be fixed quickly and easily; you must only check the precise places first and then beneath the tub.

Why You Need Bathtub Drain Stopper Removal?

Since drain stoppers are designed to sit inside the drain, most products reduce water flow when installed. However, this reduction in water flow is rarely apparent so long as debris such as hair and grime does not accumulate within the drain stopper. Unfortunately, drain stoppers’ shape, size, and operation frequently increase the probability that they will trap this dispersed residue; therefore, bathtub drain stopper removal has become compulsory.

Another reason for bathtub drain stopper removal is to repair or replace it. Some parts of the drain stopper mechanism can break or wear out, which means you can’t close and open the stopper properly. Now, the bathtub drain stopper must be removed; either the broken part needs to be replaced or the whole stopper needs to be replaced. Before fixing anything, you should know how to put in and remove various drain stoppers. For other types of bathtub drain stopper removal, click here.

What is a Pop-Up Drain Stopper?

A set of parts in your bathroom sink called a bathtub pop-up drain stopper lets you open or close the stopper on your sink drain. The stopper (the piece that goes into the drain and secures it) is closed by lifting the rod behind the bathroom sink faucet. The assembly opens up the stopper when you push down on the rod. This permits the water to flow away. This kind of bathtub pop-up drain stopper is in most bathroom sinks. An assembly’s parts work together to let water flow down your sink drain and stop water from running down your sink drain.

What Are the Parts of a Pop-Up Drain Stopper?

It is critical to understand its components before bathtub drain stopper replacement or repair, such as a pop-up stopper. Although the adjustment or repair is relatively straightforward, the part design can be confusing. The core components of a pop-up drain assembly, often found in the bathroom sinks, are as follows.
Pivot Rod: As the lift rod ascends or descends, the pivot rod transfers vertical motion to the bathtub drain stopper, which is attached to the clevis via a spring clip.
Clevis (strap or clevis strap) links the lift rod that regulates the drain to the sink’s pop-up drain.
Lift Rod: The component is typically located directly behind the faucet that opens and closes the pop-up drain.
Clevis Screw: The screw (located at the top of the clevis) that tightens the clevis to the lift rod. 

How Does a Sink Pop-Up Stopper Work?

Each bathtub drain stopper type works differently, so here we discuss how the hoe pop-u drain stopper works. In a pop-up drain stopper, a rod on the back of your sink stops the drain when you lift it. It lets water fill the sink. It opens when you push down on the rod, allowing the water-filled sink to drain if this mechanism is not working correctly because of an issue with the pivot rod and bathtub drain stopper.

The drain stopper under the sink is linked to a pivot rod. A few parts must be removed before the pivot rod can be removed. Some of these include the clevis, sealing nut, spring clip, and gasket. The sink has a sealing nut and gasket connecting a pivoting rod. The clevis is connected to the horizontal pivot rod with a small spring clip. It is a vertical strap with many holes that remain in place.

How to Remove a Pop-Up Drain Stopper?

A pop-up drain stopper, similar to other main bathtub drain stopper types, such as trip-lever stoppers, comprises a complex assembly attached via the overflow drain. These stoppers are connected to a rod assembly and positioned on the overflow faceplate of these drain stoppers lower vertically through the overflow drain. However, the rod assembly is connected to a spring on top of a horizontal rocker arm instead of a plunger. The rocker’s arm regulates the movement of a pop-up valve by passing through the tub or sink drainpipe.

The spring is compressed when the lever is in the open position, which causes the rocker arm to be pushed and the plug rises. The closed position of the spring enables the rocker arm’s upward pivoting motion, resulting in the downward reach of the stopper and sealing of the drain. Pop-up drain stoppers are prone to blockage due to the complicated rod assembly and rocker arm.

The overflow cover has a lever that you can flip to make the plug pop up and open. This makes getting to the plug and drain easy so the rocker arm assembly can be pulled off.

  • Remove the Rocker Arm and Drain Stopper Plug

Use pliers or your hands and press the sides of the drain plug. Then, pull it straight up and out of the drain. It is the right way to pull out the plug, rocker arm, and stopper simultaneously. Be careful not to pull too hard.

  • Unscrew the Overflow Faceplate

A screwdriver is needed to take the screws out of the overflow cover. Make sure to put the screws in a secure place until you are ready to put them back in. Take off the overflow faceplate to gain access to the lever and rod assembly.

  • Remove the Rod Assembly

The rod assembly should be cautiously removed from the overflow drainpipe, ensuring that every component, including the rods, spring, and lever, has been removed without any damage. If the part gets stuck, use a lubricant to move the spring and rod.

The rocker arm, spring, rods, and trip lever are some parts of the pop-up drain stopper that should be checked. Before re-inserting the stopper back in place, any parts that show signs of too much wear or damage, like rust, cracks, or bending, should be changed to avoid problems in the future. If the stopper is still in good shape, use a bathroom cleaning solution to get rid of hair, soap scum, dirt, grime, and other things that are stuck in the sink and stopper.

Put the rocker arm into the drain to start the reinstallation process. Make sure it goes all the way through the drainpipe and into the drain opening. Put the spring and rod assembly into the overflow drain while the rocker’s arm is still in place. When everything is set up right, the spring should touch the rocker’s arm and make the plug pop up. Finally, you will need to use the screws that you saved to connect the overflow faceplate, and you will also need to move the lever on the drain stopper to ensure that it works properly.

How Do You Fix a Bathtub Pop-Up Drain Stopper?

Take off the securing screws from the overflow cover plate.
Pull the lever and plate away from the overflow opening to pull out of the mechanism.
Adjust the linkage’s nut: extend it to elevate the stopper or shorten it to lower it.
Reinstall the assembly with the cover plate in its position.
The stopper and rocker linkage must be lifted. After checking the seal and removing debris or hair, put it in the drain.

Explained In Details:

When the lever or knob is turning, a prevalent issue with bathtubs is that the pop-up stopper fails to close completely, does not suit the drain flange snugly, or opens easily. Poorly closing stoppers may hinder the filling process of the tub, leading to water loss. When stoppers fail to open completely or quickly, the drainage process in the tub becomes sluggish.
A bathtub pop-up is a two-component mechanism consisting of the overflow assembly. This lever raises or lowers a rod with a spring-like end, and the stopper consists of a rocker arm extending back toward the drain. By raising the overflow lever, the rod is forced downward against the rocker arm of the stopper, resulting in the plug being raised. The rod is elevated by raising the lever, enabling the stopper’s drop-down, which obstructs the drain.
Depending on the style of the pop-up, how the stopper is seated can be modified via the rocker arm or the length of the striker rod.
To change the overflow assembly, remove the screws that attach the overflow cover plate and pull the lever and the plate from the overflow opening, thereby partially pulling the mechanism. Modify the length-adjusting fastener of the rod assembly; by lengthening it, one can elevate the stopper to a higher, while by shortening it, one can lower it. After that, reinstall the assembly and replace the cover plate.
Simply follow the bathtub drain stopper removal and the rocker’s arm from the drain to make adjustments. If a rubber seal is present, inspect it for damage and replace it as necessary. After removing debris and hair, adjust the underside nut to shorten or elongate the nut’s connection to the rocker’s arm.
Lower the arm and stopper into the drain opening to ensure a secure flange insertion, although corroded flanges may be present in older tubs.
One of the most efficient ways to keep the stopper in excellent condition is to keep the drain clean by regularly removing material such as hair, shampoo, soap residue, and other particles.

How Do You Fix a Sink Pop-Up Drain Stopper?

There are various potential causes for water to leak or clog around a sink pop-up. Fixing a sink pop-up that will not pop up or sit correctly is typically a simple matter of adjusting a few components. Frequently, the cause is an accumulation of hair near the stopper’s base or the pivot rod mechanism. On the other hand, the clevis might be misplaced.
When the knob and lift rod press down, the stopper is raised by the pivot rod. When the knob is pulled, the stopper is pulled downwards by the pivot rod. If the drain’s blockage is too high or too low, use a flashlight to inspect the drain for the components. However, pinch the spring attachment to remove the flat bar (clevis) from the pivot rod. After repositioning the rod in a different aperture of the clevis, replace the spring attachment.
In various sinks, the drain becomes blocked due to hair and other material accumulated around the stopper’s body. Pulling the cork out is necessary to clean it. Certain sinks could allow you to take it out of the hole. It is usually necessary to do work underneath the sink. The retaining nut has to be removed before the pivot rod can be extracted. Slip-joint pliers could be useful if the nut has gotten stuck in its position. You may need to rotate the stopper to separate it from the pivot rod.

Here’s more detail on how to fix the problem:
Step 1.
Try to left the stopper out by giving it a little twist. It seems to be connected to the device below. To disconnect it, reach under the sink, remove the nut that maintains the pivot rod in position, and pull it out. If you need to, use locking-jaw pliers to loosen it. The spring clip, hinge rod, seals, and screws inside a sink pop-up stopper.
Step 2:
Take the plug off the drain. Get rid of all the hair and dirt. If the stopper is broken or the seal looks old, you should get a new one.
Step 3:
Put the stopper back in the drain hole by facing the hole at the bottom of the stopper toward where the hinge rod is. To tighten the holding nut with the stopper up, put the pivot rod through the hole in the bottom of the stopper and make sure it fits. When the drain is closed, the pivot rod should rise slightly uphill from the clevis to the tailpiece.
Step 4:
Loosen the set screw on the clevis, then rotate the strap up or down such that it moves the pivot rod open and shuts the stopper. This will need the set screw to be loosened. Replace the set screw in its original place.
Step 5:
Squeeze the spring clip to free the pivot rod and fix the rod if changing the clevis screw doesn’t work. Put the rod in the next clevis hole after moving the clip up to it. You might have to make a few changes to this to get the clevis hole just right.
Step 6:
Tighten the nut if water drips from the pivot ball. You will likely need to change the seal or nuts inside the pivot ball-and-rod system. One of the best ways to keep pop-up stoppers working well is to keep drains free of hair, soap and shampoo residue, and other trash.

How Do You Clear the Blockage in the Pop-Up Stopper?

Apply a bent wire hanger to clean the lines of hair and gunk after you’ve cleaned the pop-up stopper in a different sink. Put the wire with the hook on the end into the drain and turn it around until you feel something on the end. Then, pull up and throw away everything you pull up with covered hands. You can also use the hole in the pivot rod to pull hair and other stuck items. Clean the inside of the pipe and the area around the drain with an old toothbrush. If a hanger doesn’t remove the clog, you might have to take the P-trap out from under the sink and clean it by hand.
