How to Install a New Toilet

Installing a new brand toilet is not an easy process. However, it is a process that many DIY home owners can handle. In this post, I am going to give you the simplest guide to installing a new top performance toilet. As a professional plumber, I have used this guide for a very long time and it is quite dependable.

Step 1: Prepare the Required Tools 

For your new toilet installation, there are a number of tools that you will need if you want a neat job. Keep the tools together and set them out in an easy to reach place. Here are the toilet installation tools to have.

  • Adjustable wrench
  • Plumbers Putty
  • Screwdriver
  • Toilet Installation kit
  • Safety goggles
  • Plumber’s tape
  • Jigsaw scraper
  • Silicone Caulk
  • Gloves

Step 2: Prepare Toilet Connections 

Start out with the manufacturer’s instructions. They should paint a clear picture of how your toilet looks like and whether the toilet comes readily assembled or not. If your toilet requires to be assembled before you can install then do so.

Now prepare the flange. Attach your flange to the over pipe that connects to the valve. Also slide the compression washer and the large nut on the pipe. Wrap the threads with plumbing tape (Teflon) and tighten using a wrench.

Ensure your supply line is cut to the right length. Use jigsaw cutter. Then turn off your water supply at the shut off point. Water that supplies a toilet comes through a small pipe on the wall or floor. The pipe is set at the left side of the toilet bowl.

Step 3: Organize Flange, Drain, and Base

The hollow on which a new toilet is supposed to be installed is called a plug. Make sure the plug is free of any debris or obstructions before you can install a toilet on top of it. Most plugs are often stuffed with paper to prevent debris from getting in and blocking it. Remove paper and any debris.

Now slide the closet bowls into the new flange setup. The bolts basically stick out of the floor once the flange is fixed in place. Apply wax to the bottom of the bowl. It will give you a water tight seal over your drain pipe. For an added seal, you can also run a bead of silicone caulk.

Step 4: Fix the New Toilet on the Drain

Now set your toilet on the flange. Make sure the closet bolts are aligned with the holes on the toilet’s base. Then tighten with a wrench. But do not over-tighten. Doing so could break the toilet base. Remember to use a nylon washer over each bolt and follow it with a metal washer.

Note:Use plastic retainers. Push them down to the flange. This will prevent bolts from popping over.

Step 5: Attach Tank to Bowl

First attach flexible line to the water supply. Then align the holes at the bottom of the tank to those at the top of the bowl. Attach washers on tank bolts and then set bolts through the aligned holes; before tightening the bolts using nuts.

Attach the toilet seat to the setup to complete your installation. You can now turn on the water supply and test your toilet.
