Unlike a toilet, you may not know you've cleared the drain clog until you lift the plunger. Every 30 seconds or so, lift the plunger to see if the water recedes.

Whether fixing a toilet that’s running or leaking from the base, cleaning the tank, or replacing a unit that’s beyond repair, your first step must be to drain the toilet in order to inspect ...

The Main Drain consists of a urine-receiving head designed to reduce splashing, an articulated hose, and a clip where the liquid comes out, that hooks over the edge of the toilet bowl.

If there's not enough water in the toilet, add some so that you can submerge the plunger. Insert a flange plunger into the toilet bowl. "The trick is to put it in at a 45-degree angle," says Medina.
