How To Install A Drain Pump To Add A Bathroom or Laundry Room


Many homes were not built with the convenience of a bathroom or laundry room in mind. This can be frustrating for homeowners, who may feel squeezed for space or lacking in amenities compared to modern homes. Luckily, with a little know-how and some basic tools and equipment, you can install a drain pump and convert an unused space, such as a garage or basement, into a fully functional bathroom or laundry room. In this article, we will walk you through the process of installing a drain pump and offer helpful tips and tricks along the way.

Background and Important Steps:

Before we dive into the installation process, let’s discuss some important background information and considerations. First of all, it is important to note that depending on your local regulations, you may need an occupancy permit to convert a space from a church to a residential area. Additionally, if you are working with pre-existing plumbing, it is crucial that you accurately identify and shut off any relevant water mains or other plumbing systems in the area. Safety goggles and gloves should also be worn to protect against any flying debris or sharp edges. Lastly, make sure to clear out the area in question and lay down protective coverings to avoid any unwanted mess.

Now, onto the actual installation process. Follow these important steps to install a drain pump:

  1. Determine the location of the drain pump – This is usually located in a spot beneath and slightly behind the bathroom or laundry room, and is used to help move water up and out of the space.
  2. Connect the drain to the pump – This can be done through existing plumbing, or by cutting and manipulating pipes to fit the pump.
  3. Add a check valve – This helps prevent water from flowing back into the pump, which could cause flooding or other damage in your space.
  4. Install the necessary electrical work – This includes wiring the pump to a nearby outlet or directly to the electrical panel.
  5. Connect the pump to any relevant fixtures – This includes sink, shower, and toilet lines in the case of a bathroom, or washer and dryer hookups in the case of a laundry room.
  6. Test the setup – Make sure everything is working as expected and any leaks are fixed before proceeding.

Helpful Tips and Tricks:

Here are some helpful tips and tricks to ensure your installation is successful:

  1. Use 20 amp plugs for both your washer and your pump to ensure they can both run on the same circuit.
  2. When working with electrical systems, always shut off the power supply and carefully follow wiring instructions.
  3. To install a dryer plug, make sure to properly identify the wires and connections before wiring it up.
  4. DIY memberships that offer Q&A and live streams can be a great resource for support and troubleshooting throughout the process.
  5. Jeff’s favorite tools and products, such as his recommended pipe cutting and manipulating tools, can be purchased to make the job easier and more efficient.
