How to Install a Low Flush Toilet (Part 1 of 2) How to Install a Low Flush Toilet (Part 1 of 2)

A low flush toilet can provide you with a way to save a great deal of water on an annual basis. With this type of toilet, only a small amount of water will be used when flushed. If you are considering replacing your old toilet with a low-flush model, follow the steps below to get started with planning.

Step 1 - Shopping for a Toilet

The first part of the process will involve choosing the right toilet. As you compare models, find out information about how much water each one uses. You should see an EPA WaterSense sticker on the side of the box if it has been certified as a low flow toilet. If it does not have the sticker, it did not meet the qualifications that have been set forth by the EPA.

Step 2 - Flushing Mechanism

When you are looking at the different toilet options, you will also want to pay special attention to the flushing mechanism. There are many options here:

  • Gravity Assisted Flushing Mechanism - This type relies on the power of gravity to flush the water down the bowl and remove the waste. While this is a common type of flush mechanism, it is not necessarily the most effective.
  • Pressure Assisted Flushing Mechanism - This type uses air pressure to increase the power of the flush. This also allows the toilet to function with much less water, but it is very loud when you flush the toilet.
  • Electronic Assisted Mechanism - This type of toilet uses an electronic pump to increase the amount of pressure when you flush the bowl. This is definitely quieter than the pressure assisted toilets and you can get by with low amounts of water.

Step 4 - Gathering the Tools

Before you can begin installation, you must gather the tools and materials you will need:

  • Screwdriver
  • Wrench
  • Caulk
  • Caulk Gun
  • Old carpet or newspapers
  • Flexible water supply line

You should also purchase a new wax ring unless one comes in the box with the toilet. You should also have some type of tool that you can use to scrape the old wax up off of the floor.

Step 5 - Preparation

Before you get started actually installing the new toilet, you should prepare for the job. When you take out the old toilet, it will be dirty and wet underneath. Find get an old piece of carpet or newspapers that you can set the old toilet on so that the water does not get out onto your flooring. 

You may also want to familiarize yourself with the new low flow toilet that you purchased. Read the instruction manual that comes with the toilet so that you will understand the basic process of installing that particular model. Every toilet will be very similar, but some of them have a few subtle differences that you need to keep in mind. You should also make sure that the supply line you have will fit the new toilet.
