How to Work Bathtub Cable Drain?

Understanding of bathtub cable drain;

Bathtub cable drains, also known as cable-operated bath wastes or cable-driven bath drains, are a type of drain mechanism that uses a cable to control the opening and closing of the drain. This system offers a smooth and reliable way to operate the bathtub’s drainage, eliminating the need for internal linkages that can break or become tangled.

Here’s a simplified step-by-step guide on how a bathtub cable drain works:

1. Setup:
   • The bathtub cable drain system consists of a drain stopper, an overflow plate, a cable, and a control knob.
   • The control knob is typically positioned near the overflow plate on the tub.
   • The cable connects the control knob to the drain stopper.
2. Operation:
   • Depending on the design, you’ll turn or push the control knob when you want to fill the bathtub with water.
   • This action pulls or releases the cable inside the overflow tube, which is attached to the drain stopper at the bottom of the tub.
3. Opening the Drain:
   • When the control knob is turned or pushed to the open position, it either pulls the cable or releases it in a manner that lifts the drain stopper, allowing water to flow out of the bathtub.
4. Closing the Drain:
   • Conversely, when you want to stop the water from draining, turning or pushing the control knob in the opposite direction causes the cable to move in a way that positions the drain stopper to seal the drain.
5. Advantages:
   • One of the primary benefits of a cable drain system is its reliability. Since there are no internal linkages to get tangled or broken, the system tends to have a longer lifespan and fewer issues.
   • It provides a clean look because the overflow plate and control knob can be combined into one piece.
   • Maintenance is generally simpler because, in most designs, there’s no need to disassemble the overflow to reach the mechanism.
6. Maintenance:
   • Over time, like all moving parts, the cable can wear out or become misaligned. It may need adjustment or replacement if the drain becomes hard to operate.
   • Removing the drain stopper and cleaning any hair or debris that might collect there is a good practice, ensuring smooth operation and preventing clogs.

In conclusion, a bathtub cable drain provides an efficient and aesthetically pleasing way to control the drainage of your bathtub. Its simple mechanism ensures reliable function, and with basic maintenance, it can serve a household for years. A cable-operated bathtub drain might be a modern and dependable choice if a bathroom renovation or update is considered.

What Is A Cable-Driven Drain?

The cable-driven drain is a bathtub drain kit used to drain the wastewater from the tub. To clarify, it is a drain for the bathtubs, powered by a cable, to stop and allow the water to flow from the tub to the main wastewater line. In addition, it will help you to control the overflow of your bathtub.

Cable-Driven Drain Components

A cable-driven drain combines two separate sections: the main drain and the overflow. The upper part is the overflow, and the bottom is the main drain. In addition, these two sections consist of some more elements.

In the overflow section, first of all, there is a faceplate. It is also known as a control knob. This is because it is the thing with which you will control the drain kit. In addition, you will see a strainer flange and a rubber gasket underneath the plate. All these attach with a small rod connecting them to the cable.

On the other hand, the main drain section has a pop-up stopper at its face. Moreover, this section also has a gasket and strainer flange, like the overflow part. This time, however, a connecting nut (with a hole inside) connects them. Finally, the stopper goes inside the nut hole and completes the main drain.

After that, these two sections connect with the help of pipes. The connecting pipe also comes in two variations. It could be a Tee with two other pieces of pipe OR only a flexible plastic pipe. In the end, a metal cable runs outside the line and links a knob to the stopper from the overflow. 

Steps to Install a Bathtub Cable Drain:

Pre-Installation Preparations:

• Remove Old Drain and Overflow: Remove any existing drain and overflow components before installing a new bathtub cable drain.
• Clean the Area: Make sure the drain and overflow holes are clean, removing any residue or old plumber’s putty.

Installation Process:

1. Apply Plumber’s Putty: Roll a small amount of plumber’s putty into a snake shape and place it around the drain hole.
2. Install Drain Flange: Insert the drain flange into the drain hole and press it down into the putty.
3. Tighten Drain Body: From beneath the tub, attach the drain body to the drain flange and tighten it using a pipe wrench.
4. Connect Cable to Drain: The cable will typically connect to a mechanism in the drain body. Secure it as per the manufacturer’s instructions.
5. Install Overflow Cover: Apply the plumber’s putty or caulk around the overflow hole, then attach the overflow cover using screws. This is where your cable control knob will usually be located.
6. Attach Cable to Overflow: Insert the cable through the hole in the overflow cover and connect it to the control knob.
7. Test Mechanism: Before sealing everything up, test the cable drain mechanism to ensure it appropriately opens and closes the drain.
8. Apply Teflon Tape: Wrap Teflon tape around the threading where the drainpipe will connect.
9. Connect Drainpipe: Screw the drainpipe into the drain body and tighten it using a pipe wrench.
10. Seal and Test: Seal any remaining openings or connections with silicone caulk. Wait for the caulk and any other sealants to dry, per the manufacturer’s recommendations, and then test for leaks by filling the bathtub and draining it while inspecting the overflow.

Final Checks:

1. Water Test: Fill the bathtub with water and test the cable drain to ensure it opens and closes properly.
2. Check for Leaks: Fill the bathtub to the overflow level to ensure no leaks around the overflow or drain.

If everything is working correctly, your installation is complete. If not, you may need to re-check your connections and seals and tighten or re-apply sealant.

Remember that improper installation can lead to leaks or other issues, so if you’re uncomfortable doing this yourself, it may be best to hire a professional.

Connect Them

After the installation of both sections, you will need to connect them. To do that, measure the pipe pieces accurately with your tub and cut off the extra pipes if necessary. Then, connect them with the Tee pipe. Or, if you have a flexible pipe, cut the extra pipe after the measurement and attach it to both ends. 

Do not forget to tighten each joint of the pipes. Also, use some plumber putty or silicone gel (if possible) in the bathtub holes while installing. Hopefully, the cable is already attached to the head pipes of both sections. So, your cable-driven drain is ready for use. You can now test it and start using it. 

Sizes of Bathtub Cable Drains:

Bathtub cable drains are designed to fit the standard sizes of bathtubs, but they do have variations based on the design and style of the tub.

• Standard Bathtub Drain Size: The most common size for bathtub drains is 1 ½ inches in diameter. This is the usual size for the drain hole itself.
• Overflow Pipe: This usually measures about 1 ½ inches in diameter, though sizes can vary.
• Cable Length: The length of the cable that connects the overflow control knob to the drain mechanism can vary. Typically, it’s designed to span the distance from the overflow hole to the drain, with some extra length to ensure smooth operation. This might range from 12 to 30 inches or even longer for larger tubs.

How to Use a Bathtub Cable Drain:

Using a bathtub cable drain is generally straightforward:

• Fill the Tub: As you fill your bathtub with water, the drain should be open to remove any cold water or debris.
• Close the Drain: Once ready to soak, use the control knob at the overflow to close the drain. This usually involves turning the knob for most cable drains, though the specific motion (clockwise/counter-clockwise or push-pull) may vary based on the model.
• Drain the Tub: Once you’re done with your bath, turn the control knob again to open the drain and let the water out.
• Maintenance: Every once in a while, it’s a good idea to open and close the drain mechanism when the tub is empty to ensure the cable moves freely. It might need cleaning or maintenance if you notice any issues or the drain doesn’t seal properly.

Always refer to the manufacturer’s specific guidelines and instructions regarding the sizes and usage of their bathtub cable drain product. If you are unsure about the size of your bathtub drain or how to operate it, consulting with a plumbing professional can provide clarity.

How to Check The Bathtub Cable Drain

Checking the quality of a bathtub cable drain (or any plumbing fixture, for that matter) involves a combination of visual inspections, functional tests, and understanding the materials and brands involved. Here’s a comprehensive guide to evaluating the quality:
