STEP 1: The first step is to shut off the water supply to your toilet. Then flush and hold the lever down to drain the water from your tank.

STEP 2: Place a bucket underneath your toilet tank to catch any excess water.

STEP 3: Disconnect your water supply line. Locate and remove all old nuts, bolts, and washers from the toilet tank.

STEP 4: Carefully lift up on the tank from the bowl and remove the old tank-to-bowl sponge gasket. 

STEP 5: Place the new red sponge gasket over the mounting nut threads. Need a new tank to bowl gasket? Find one here.

STEP 6: Carefully set the tank onto the bowl. Use the bolts, rubber washers, washers, and hex nuts, to attach the tank to the bowl. Apply downward pressure to keep the tank level as you tighten the nuts in an alternating fashion until the tank is stable.

STEP 7: Do not over tighten the nuts; doing so may cause the porcelain to crack.

STEP 8: Reattach the water supply line.

STEP 9: Turn the water supply on to complete your installation.
