Overview

If you need to replace or add a new toilet in your home, follow these directions. Please make sure to read through it carefully to make sure you have all necessary supplies.

What You'll Need

Tools:

Wrench, channel-type pliers, wax ring, large slotted screwdriver,

Materials:

New Toilet, wax toilet ring.

 

Step 1

Step 1

Clean and inspect the old closet flange. Look for breaks or wear. Also inspect the flooring around the flange. If either the flange or floor is worn or damaged, repair the damage. Use a rag and mineral spirits to completely remove residue from the old wax ring. Insert new closet bolts (don’t reuse old ones) into the openings in the closet flange. Make sure the heads of the bolts are oriented to catch the maximum amount of flange material.


Step 2

Step 2

Remove the wax ring and apply it to the underside of the bowl, around the horn. Remove the protective covering. Do not touch the wax ring. It is very sticky.


Step 3

Step 3

Lower the bowl onto the flange, taking care not to disturb the wax ring. The holes in the bowl base should align perfectly with the tank bolts. Add a washer and tighten a nut on each bolt. Hand tighten each nut and then use channel-type pliers to further tighten the nuts. Alternate back and forth between nuts until the bowl is secure. DO NOT OVERTIGHTEN.


Step 4

Step 4

Attach the toilet tank. Some tanks come with a flush valve and a fill valve preinstalled, but if yours does not, insert the flush valve through the tank opening and tighten a spud nut over the threaded end of the valve. Place a foam or rubber spud washer on top of the spud nut.


Step 5

Step 5

Adjust the fill valve as directed by the manufacturer to set the correct tank water level height and install the valve inside the tank. Hand-tighten the nylon lock nut that secures the valve to the tank (inset photo) and then tighten it farther with channel-type pliers.


Step 6

Step 6

With the tank lying on its back, thread a rubber washer onto each tank bolt and insert it into the bolt holes from inside the tank. Then, thread a brass washer and hex nut onto the tank bolts from below and tighten them to a quarter-turn past hand tight. Do not overtighten.


Step 7

Step 7

Position the tank on the bowl, spud washer on the opening, bolts through bolt holes. Put a rubber washer followed by a brass washer and a wing nut on each bolt and tighten these up evenly.


Step 8

Step 8

You may stabilize the bolts with a large slotted screwdriver from inside the tank, but tighten the nuts, not the bolts. You may press down a little on a side, the front, or the rear of the tank to level it as you tighten the nuts by hand. Do not overtighten and crack the tank. The tank should be level and stable when you’re done.


Step 9

Step 9

Hook up the water supply by connecting the supply tube to the threaded fill valve with the coupling nut provided. Turn on the water and test for leaks.


Step 10

Step 10

Attach the toilet seat by threading the plastic or brass bolts provided with the seat through the openings on the back of the rim and attaching nuts.
