Removing a stuck bathtub drain can be tricky, especially with a plastic trap. Here are some steps you can follow to try and free it without damaging the trap:
1. **Apply Lubricant**: Use a penetrating oil or a silicone-based lubricant around the edges of the drain plug. Let it sit for about 10-15 minutes to help loosen any debris or corrosion.
2. **Use a Rubber Grip**: If the drain plug has a knob or handle, try using a rubber grip or a pair of pliers with a cloth wrapped around the handle to provide better grip without damaging it.
3. **Heat Application**: Carefully apply heat using a hairdryer around the drain area. The heat can expand the metal slightly, which may help loosen the plug. Be cautious not to overheat or damage the surrounding materials.
4. **Gentle Tapping**: Lightly tap around the drain with a rubber mallet or a similar tool. This can help dislodge any debris that may be causing it to stick.
If these methods don’t work, it might be best to consult a licensed plumber to avoid damaging the trap or causing leaks. Costs for a plumber can range from $75 to $150 per hour, depending on your location. As a next step, consider getting 2-3 local quotes on Handyman.com to find a professional who can assist you.
