A Step-by-Step High-Efficiency Toilet Installation Guide

Are you considering upgrading your bathroom with a high-efficiency toilet (HET)? It’s a smart choice! High-efficiency toilets are not only better for the environment, but they can also help you cut down on water bills without compromising performance. This guide walks you through every step of the installation process, from removing your old toilet to ensuring a perfect finish for your water-saving upgrade.

Why Choose a High-Efficiency Toilet?

High-efficiency toilets are specifically designed to use less water per flush, with many models consuming as little as 1.28 gallons compared to the standard 1.6 gallons. Over time, this can save thousands of gallons of water annually for an average household. Besides being eco-friendly, HETs are sleek, modern, and a valuable improvement to any home.

Whether you’re a professional plumber or a handy homeowner, this guide will show you how to install a high-efficiency toilet quickly and efficiently.


Tools and Materials You’ll Need

Before you start, gather these essential tools and materials to make your installation smooth and hassle-free:

Tools:

  • Adjustable wrench
  • Screwdriver set
  • Tape measure
  • Utility knife
  • Plumber’s putty
  • Level

Materials:

  • New high-efficiency toilet
  • Wax ring (included with most toilet kits)
  • Bolts and caps
  • Water supply line
  • Sponge or bucket (for cleanup)

Step-by-Step Installation Guide

Follow these steps to remove your old toilet and install your new high-efficiency toilet with confidence.


1. Preparing the Area

Step 1. Shut Off the Water Supply

Locate the shut-off valve behind the toilet and turn it clockwise to stop water flow. Flush the toilet to drain as much water as possible. Use a sponge or bucket to remove any remaining water in the tank and bowl.

Step 2. Disconnect the Water Supply Line

Use an adjustable wrench to unscrew the water supply line from the base of the toilet. Keep a bucket handy to catch any excess water.

Step 3. Remove the Old Toilet

Unscrew the bolts holding the toilet to the floor. Gently rock the toilet back and forth to loosen the seal of the wax ring. Lift the toilet off the flange and set it aside. Be cautious as old toilets can still contain residual water.


2. Installing the New Toilet

Step 1. Install the Wax Ring

Place the new wax ring onto the toilet flange or the base of the toilet. Make sure it’s centered to prevent leaks.

Step 2. Position the Toilet

Carefully lower the new toilet onto the flange, aligning the bolts with the holes on the base. Press down gently to create a solid seal with the wax ring.

Step 3. Secure the Toilet

Add washers and nuts onto the bolts, tightening them evenly. Avoid overtightening as it can crack the porcelain. Snap the bolt caps into place for a polished appearance.


3. Connecting the Water Supply

Step 1. Attach the Water Supply Line

Connect the water supply line to the base of the tank and tighten it with the adjustable wrench. Be sure it’s secure but not overly tight to avoid damaging the threads.

Step 2. Turn On the Water

Slowly turn on the shut-off valve and allow the water to fill the toilet tank. Check for any leaks around the supply line and base.


4. Final Checks

Step 1. Test the Flush

Flush the toilet several times to ensure it works properly and that there are no leaks around the base or supply line.

Step 2. Level the Toilet

Place a level across the bowl to ensure it’s even. If it’s tilting, make adjustments at the base.

With these steps completed, your high-efficiency toilet is now ready to use!


Troubleshooting Common Issues

Here are some quick fixes for common hiccups you might encounter during installation:

Leaks Around the Base

Likely caused by improper placement of the wax ring. You may need to reset the toilet and ensure the ring is centered correctly.

Water Supply Line Leaks

Check that all connections are secure and replace a worn or damaged supply line if necessary.

Weak Flush

Ensure there’s no debris in the water supply line or clogging in the toilet trapway. If it persists, consult the manufacturer’s manual.

Wobbly Bowl

Use shims around the toilet base to level it, then apply caulk to seal the edges for added stability.
