How to Remove a Stuck Bathtub Drain Flange · Step 3 of 5

Use a large adjustable wrench to hold the lower, larger hex nut on the extractor tool stationary. With a second adjustable wrench, turn the smaller, square nut on the very top of the tool clockwise. This action expands the serrated base of the tool, forcing it to press firmly against the inside walls of the drain fitting and locking it securely in place.
Goal: Lock the tool inside the drain fitting
- Ensure the tool is tightly secured before attempting to unscrew the drain. If it's not tight enough, it may slip and damage the inside of the drain or the tool itself.

FAQs
What should I do if the drain key or wrench just slips, or the flange doesn't budge after applying penetrating oil?
If initial attempts fail, the flange is likely severely corroded or the putty is rock-hard. Apply more penetrating oil, like KROIL, and let it sit for several hours or even overnight to allow it to fully penetrate. If it still won't turn, your last resort is to carefully cut the flange using a rotary tool with a metal cutting wheel, making two opposing cuts without damaging the drain pipe threads.
Is it safe to cut the drain flange, and what precautions should I take?
Cutting the flange is a last resort and requires careful attention to safety. Always wear safety glasses and gloves to protect against metal fragments and sparks. Use a rotary tool with a metal cutting wheel, making two shallow, opposing cuts from the inside of the flange, being extremely careful not to cut into the drain shoe's threads below the flange.
How can I minimize the risk of damaging the bathtub or drain pipe during removal?
To prevent damage, protect the tub surface with a rag or towel if using a wrench or other tools that might slip. When cutting the flange, make shallow passes and continuously confirm you are only cutting the flange metal. Avoid excessive force, as that can warp the drain shoe or break connections further down the pipe.
Given this is a 'beginner' project, what are the most essential tools I absolutely need to have on hand?
Beyond basic safety gear, you'll definitely need a high-quality penetrating oil like KROIL, an adjustable wrench, and a specialized drain key or removal tool. For very stuck flanges, a rotary tool like the WEN 101-Piece Rotary Tool Kit with a metal cutting wheel (Stark 5 in. Metal Cut Saw Wheel) becomes essential. A putty knife and rags are also vital for preparation and cleanup.
