Remove the Old Tank

Don't let toilet replacement scare you; it's easy to do.

Start by removing old toilet.

Turn off water.

Flush old toilet and remove excess water with sponge.

Loosen T-bolts securing tank to floor, and remove the old tank.

Remove the Wax Ring

Rock bowl side to side to loosen wax seal.

Remove bowl and use putty knife to remove old wax seal.

Tip: Caution, hazardous gases could rise from pipe.

Wipe away remaining wax with rag or damp sponge.

Position the New Bowl

With new toilet bowl resting on padded surface, attach new wax seal to bottom of bowl.

Align new bowl outlet with flange. Apply weight and press down to set wax seal.

Tip: Do not move bowl after seal has touched flange; seal could break and cause leakage. If seal is broken, replace with new one.

Secure the Bowl

Place plastic cap bases over T-bolts in upright position.

Slide washer and thread nut over T-bolt. Evenly tighten nut over T-bolt until secure. Do not over-tighten; this could damage toilet.

Shorten bolt with hacksaw, if necessary. Do not touch bowl with hacksaw; this could damage it.

Snap plastic caps onto cap bases.

Slide retaining bolts into brackets on bottom of tank.

Install the New Tank

Press gasket onto tank outlet.

Position tank on bowl by centering gasket on bowl inlet.

Assemble washers and nuts on tank bolts. Alternately tighten nuts until tank is level and mounting bracket tabs make contact with bowl.

Place long carpenter's level on top of tank to check for level.

Connect the Water Supply and Finish Installation

Connect water supply to tank. Open valve and check for leaks.

Tip: Place bucket under valve before turning it on.

Install the toilet seat, and place the tank cover on the tank.

Adjust flush volume by pinching C-clip and sliding it up or down float rod.
