Step 2 · Choose the Correct Drain Bladder Size
Examine the packaging of your drain cleaning bladder to confirm it is designed for the diameter of your drain pipe. Bladders are not one-size-fits-all; they are rated for specific pipe size ranges, such as 1.5 to 2-inch pipes or 3 to 4-inch pipes. Based on our assumption of a 2-inch bathtub drain, you will need a bladder rated for that size. Using a bladder that is too small for the pipe will fail to create a proper seal, rendering it ineffective. Using one that is too large may not fit into the drain opening or could potentially damage the pipe when it inflates.
