When buying bathroom fixtures and hardware, look for the WaterSense label.

Pro Tip

WaterSense is an Environmental Protection Agency partnership program to promote water-efficient products which offer significant water savings and meet strict performance standards.

Step 3

Replace the Showerhead and Faucets

Replacing a 2.75 gpm showerhead with a 1.75 water-conserving showerhead can save a family of four more than 7,700 gallons of water a year.

Fixing leaky faucets and installing faucets with water-saving aerators can save hundreds of gallons of water per year.

Pro Tip

Save water by turning off faucet while brushing teeth or shaving.

Step 4

Choose a New Toilet

Toilets use 27 percent of daily indoor water in US homes

Replacing older, less efficient toilets with 1.28-gallon High-Efficiency Toilets (HETs) can save up to 16,500 gallons of water per year

Dual-flush toilet with 1.6 gallons per flush (gpf) and .8 gpf flush options can save as much as 6000 gallons of water a year over a traditional, 1-flush 1.6-gallon toilet

Pro Tip

For greatest waters savings, use the .8-gpf button for liquids, the 1.6-gpf button for solids.

Step 5

Remove the Old Toilet

Turn off water. Flush old toilet and remove excess water with sponge.

Remove old tank. Loosen T-bolts that secure tank to floor.

Rock bowl from side to side to loosen wax seal. Remove bowl and use putty knife to remove old wax seal.

Wipe away remaining wax with rag or damp sponge.

Pro Tip

Caution, there is a risk of hazardous gases rising from pipe.

Step 6

Install the Toilet 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.

If seal is broken, replace it.

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 as this may damage toilet. Shorten bolt with hacksaw if necessary. Do not touch bowl with hacksaw as this may damage it

Snap plastic caps onto cap bases.

Pro Tip

Do not move bowl after seal has touched flange; this may break seal and cause leakage.

Step 7

Install the Toilet Tank

Slide retaining bolts into brackets on bottom of 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.

Step 8

Check for Level and Finish Installation

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

Connect water supply to tank.

Open valve and check for leaks. Place bucket under valve before you turn it on.

Install toilet seat, and place tank cover on tank.

Pro Tip

Save even more water by adjusting flush volume with C-clip.
