Removing a push down tub drain may seem like a simple task, but it requires the right approach to avoid damaging the finish or losing small components down the waste line. This guide walks you through the process methodically, ensuring you understand the mechanics before applying force. Whether you are dealing with a stubborn lever or a seized linkage, following these steps will save you time and potential frustration.
Understanding the Push Down Drain Mechanism
Before attempting removal, it helps to understand how the mechanism functions internally. A push down drain operates through a simple yet effective system involving a pivot rod and a rubber stopper. When you press down on the lever, it lifts a horizontal rod underneath the drain, allowing the rubber component to retract and let water flow freely. To remove push down tub drain parts effectively, you must reverse this process while being mindful of the linkage hidden behind the overflow plate.
Tools You Will Need
Having the correct tools on hand streamlines the process significantly and reduces the risk of stripping screws or scratching the tub. You do not need an extensive toolkit, but specific items are essential for a smooth removal. Gather the following items before you begin work to ensure you are prepared for every scenario.
- Adjustable wrench or basin wrench
- Screwdriver (flathead and Phillips)
- Pliers (needle-nose preferred)
- Flashlight or work light
- Rag or bucket
- Penetrating oil (if dealing with rust)
Step-by-Step Removal Process
The actual procedure involves accessing the linkage mechanism that connects the drain lever to the stopper. Start by positioning yourself comfortably in front of the tub and locating the access point under the tub. This usually requires you to open a small door or panel beneath the faucet handles where the pivot rod enters the drain tailpiece. Shining a flashlight into this cavity is crucial for seeing the nuts and clips that secure the hardware.
Disconnecting the Linkage
With the area illuminated, identify the pivot rod and the rod nut that holds it in place. You will need to loosen this nut to free the linkage from the drain assembly. If the nut is corroded, apply a small amount of penetrating oil and allow it to sit for several minutes. Once loose, use pliers to grip the nut while turning the rod slightly to unscrew it. Be careful not to let small washers or clips fall into the wall cavity, as they can be difficult to retrieve later.
After disconnecting the rod, the drain flange will no longer be held in the raised position. At this stage, you can gently lift the drain stopper out of the basin. If resistance is met, check the drain body for hair or debris that might be catching on the rubber seal. Cleaning the surface at this point ensures that the drain operates smoothly when you reinstall it or fit a new push down tub drain.
Troubleshooting Common Issues
Encountering resistance is normal, especially in older installations where mineral buildup or rust can weld components together. If the drain refuses to budge, check the relationship between the lift rod and the drain tailpiece. Sometimes the rod is simply disconnected, making it appear stuck when the issue is actually a misalignment. Inspecting the linkage rod for bends or damage can save you from applying excessive force that might crack the tub overflow plate.
- Sticky Lever: Lubricate the pivot point with silicone grease.
- Leaking Drain: Ensure the rubber seal is clean and seated properly.
- Hardware Corrosion: Replace rusty nuts and washers during reinstallation.
Reassembly and Final Checks
Once the old drain is free, take a moment to inspect the drain hole for cracks or chips before installing the new push down tub drain. Reassembly is essentially the reverse of removal, but attention to detail is vital to prevent future leaks. Thread the pivot rod back through the assembly and tighten the nut securely, but avoid overtightening which can strip the threads. Ensure the lift rod returns to a horizontal position when the drain is fully closed, indicating proper tension on the linkage.
After reattaching the hardware, test the mechanism by filling the tub and observing the water level. Verify that the drain holds water without dripping and that the lever moves smoothly without sagging. A successful removal and reinstallation mean you have restored the functionality of your tub drain without the need for professional assistance.
