Gather the necessary tools and materials

Before starting the installation process, it is important to gather all the necessary tools and materials. Here is a checklist to ensure you have everything you need:

  • Toilet bowl and tank
  • Toilet flange
  • The ejector pump and associated components
  • PVC pipes
  • Shut-off valves
  • Water supply line
  • Drainage pipe
  • Wrenches and pliers
  • Adjustable wrench
  • Hacksaw
  • Teflon tape
  • Silicone sealant
  • Screwdriver
  • Level
  • Measuring tape

Having these tools and materials ready will make the installation process smoother and more efficient.

Choose the location for the toilet

Determining the best spot for your basement toilet is crucial for both functionality and convenience. Consider the following factors when selecting the location:

Determining the best spot

Take into account the layout and use of your basement space to determine the most suitable spot for the toilet. It should be easily accessible and provide enough room for comfortable use.

Considering the proximity to plumbing and sewage lines

Ensure that the chosen location is in close proximity to existing plumbing and sewage lines. This will make the installation process easier and more cost-effective. If the desired location is far from these lines, additional plumbing may be required.

Prepare the area for installation

Before installing the toilet, it is important to properly prepare the area. This involves the following steps:

Clearing the space

Remove any obstructions or debris from the intended location to provide a clean and clear space for installation. This includes removing any items or furniture that may hinder the installation process.

Checking for any structural issues

Inspect the surrounding area for any structural issues, such as cracks or uneven flooring. It is important to address these issues before installing the toilet to ensure the stability and longevity of the installation.

Ensuring proper ventilation

Basements often lack natural ventilation, so it is crucial to ensure proper ventilation for the toilet area. Consider installing an exhaust fan or a venting system to prevent odors and humidity buildup.

Install the sewage ejector system

To properly install a basement toilet, a sewage ejector system is required. Follow these steps for installing the ejector system:

Selecting the appropriate type of ejector system

There are different types of sewage ejector systems available, including submersible and pedestal systems. Consider your specific basement layout and plumbing requirements to choose the most suitable system for your needs.

Determining the capacity needed

The capacity of the ejector system is determined by the number of fixtures it will be servicing. Calculate the total fixtures, including toilets, sinks, and showers, to determine the appropriate capacity for your ejector system.

Connecting the ejector pump to the main sewer line

Connect the ejector pump to the main sewer line using PVC pipes. Ensure proper alignment and secure connections to prevent leaks. It is recommended to consult a professional plumber for this step if you are not familiar with plumbing installations.

Install the toilet flange

The toilet flange is a critical component that connects the toilet bowl to the drainpipe. Follow these steps to install the toilet flange:

Choosing the right flange

Select a toilet flange that is suitable for your specific toilet and installation requirements. The flange should be made of durable materials and compatible with the existing plumbing system.

Positioning and securing the flange

Position the flange over the drainpipe and align it with the mounting holes on the toilet bowl. Secure the flange to the floor using screws or bolts, ensuring a tight and stable connection.

Rough-in the plumbing

Rough-in plumbing involves connecting the PVC pipes from the toilet flange to the ejector pump. Here’s how to rough-in the plumbing for your basement toilet:

Measuring and cutting the PVC pipes

Measure the distance between the toilet flange and the ejector pump. Cut the PVC pipes to the appropriate lengths using a hacksaw. Ensure clean, straight cuts for proper pipe fitting.

Connecting the pipes to the toilet flange and ejector pump

Connect the PVC pipes to the toilet flange and the ejector pump, ensuring a secure and watertight connection. Use PVC cement and primer according to manufacturer instructions to bond the pipes together.

Install the toilet bowl and tank

Now that the plumbing is in place, it’s time to install the toilet bowl and tank. Follow these steps for a proper installation:

Attaching the bowl to the flange

Carefully lower the toilet bowl onto the flange, ensuring that the mounting bolts pass through the holes on the bowl base. Press the bowl firmly onto the wax ring to create a watertight seal. Secure the bowl to the flange using nuts and washers, tightening them evenly.

Setting up the tank and connecting it to the bowl

Attach the tank to the toilet bowl, aligning the mounting holes. Insert bolts through the holes and secure them with nuts and washers. Connect the water supply line to the bottom of the tank, ensuring a tight connection. Use Teflon tape on the threaded connections to prevent leaks.

Connect water supply and drainage

With the toilet bowl and tank installed, it’s time to connect the water supply and drainage. Follow these steps:

Installing shut-off valves

Install shut-off valves on the water supply line near the toilet. These valves allow you to shut off the water supply to the toilet in case of maintenance or repairs.

Connecting the water supply line

Connect the water supply line to the shut-off valve and the bottom of the toilet tank. Ensure a secure and leak-free connection. Turn on the water supply and check for any leaks. If necessary, tighten the connections or replace any faulty parts.

Connecting the drainage pipe to the ejector pump

Connect the drainage pipe to the outlet of the ejector pump using PVC fittings. Ensure a tight and secure connection to prevent any leaks or sewer gas odor. Consult a professional if you are unsure about the proper connections.

Test the toilet and make adjustments

Before finalizing the installation, it is essential to test the toilet and make any necessary adjustments. Follow these steps:

Filling the tank and checking for leaks

Turn on the water supply to fill the toilet tank. Check all connections for any signs of leaks. If there are leaks, tighten the connections or replace faulty parts as needed.

Adjusting the water level and flush mechanism

Check the water level in the tank and adjust it if necessary. Follow the manufacturer’s instructions to adjust the float and refill mechanism. Ensure proper flushing and efficient water usage.

Finish the installation

To complete the basement toilet installation, follow these final steps:

Sealing around the toilet base

Apply silicone sealant around the base of the toilet to create a waterproof seal. This will prevent any water or sewage leaks from the base and ensure a clean and hygienic installation.

Installing the toilet seat

Attach the toilet seat according to the manufacturer’s instructions. Ensure proper alignment and a secure fit. Test the seat for stability and adjust as needed.

Cleaning up the work area

Clean up any debris, tools, or materials left from the installation process. Wipe down the toilet and surrounding area to remove any dirt or dust. Dispose of any waste or packaging materials responsibly.

By following this step-by-step guide, you can successfully install a basement toilet. Remember to consult a professional plumber if you encounter any difficulties or are unsure about certain steps.
