Once the tub overflow is firmly sealed with duct tape you are ready to clear the clogged drain. Proceed as follows:
- Remove the tub drain stopper. You may have to turn it back and forth a little while pulling up.
- Once the stopper is removed open the hot water faucet (not cold) and let the water run until it is hot.
- Once there is about 1” to 2” of water in the tub bottom, place the cup plunger over the drain and using firm pressure, quickly press the plunger down and pull up 5 to 6 times.
- You will see the duct tape over the overflow move back and forth as the drain line changes from a pressured to vacuum state.
- Lift the plunger to allow the clog debris to rise and remove any clumps of hair or other things that have come up.
- Repeat the procedure of placing the plunger over the drain and rapidly moving the plunger up and down.
- Repeat this process until the drain starts to flow freely.
- Remove the duct tape and replace the drain stopper.
