Plumbing an Upflush Toilet: A Comprehensive Guide
Upflush toilets, also known as macerating toilets, are a practical solution for spaces with limited plumbing, such as basements or small bathrooms. They grind waste into a fine slurry, allowing it to be pumped away through small-diameter piping. Here's a step-by-step guide on how to plumb an upflush toilet, ensuring a professional and efficient installation.
Understanding Upflush Toilets
Before we dive into the installation process, it's crucial to understand the components of an upflush toilet system. These toilets consist of a toilet bowl, a macerating pump, and a control panel. The pump is usually located in a separate tank or a compartment beneath the toilet.
Tools and Materials Needed
- Upflush toilet kit (including toilet bowl, macerating pump, and control panel)
- PVC pipe and fittings
- PVC cement and primer
- Pipe cutter or hacksaw
- Adjustable wrench
- Screwdriver (Philips and flathead)
- Tape measure
- Level
- Plumber's putty
- Gloves and safety glasses
Preparation and Planning
Before you begin, ensure you have the correct upflush toilet kit for your space. Measure the area where the toilet will be installed, and check the dimensions of the kit to ensure it fits. Also, locate the nearest drain and power source, as these will be crucial for installation.
Installing the Toilet Bowl
Begin by installing the toilet bowl. Follow these steps:
- Position the toilet bowl in place, ensuring it's level and centered.
- Mark the location of the mounting bolts and drill pilot holes.
- Attach the mounting bolts and secure the toilet bowl to the floor using nuts and washers.
- Apply plumber's putty around the base of the wax ring, then attach the toilet to the floor flange, ensuring a tight seal.
Plumbing the Waste Line
Next, connect the waste line to the macerating pump. Here's how:
- Measure and cut the PVC pipe to the appropriate length, ensuring it reaches from the toilet outlet to the pump inlet.
- Apply PVC primer and cement to the pipe and fitting, then connect the pipe to the toilet outlet and pump inlet.
- Secure the connection with clamps if necessary.
Plumbing the Vent Line
Upflush toilets require a vent line to prevent odors and ensure proper operation. Here's how to install one:

- Measure and cut the PVC pipe to the appropriate length, ensuring it reaches from the pump vent to the roof or exterior wall.
- Apply PVC primer and cement to the pipe and fitting, then connect the pipe to the pump vent and the vent stack.
- Secure the connection with clamps if necessary.
Wiring the Control Panel
Upflush toilets require electrical power to operate. Here's how to wire the control panel:
- Turn off the power at the main electrical panel.
- Run a dedicated 120V, 15A circuit from the power source to the control panel.
- Connect the wires according to the manufacturer's instructions, ensuring the polarity is correct.
- Turn the power back on and test the toilet.
Testing the System
Before using the upflush toilet, it's essential to test the system to ensure it's working correctly. Here's how:
- Fill the toilet bowl with water.
- Flush the toilet and observe the pump. It should activate and pump the waste away.
- If the pump doesn't activate, check the wiring and ensure the toilet is properly plumbed.
Congratulations! You've successfully plumbed an upflush toilet. Regular maintenance, such as cleaning the pump and checking the connections, will ensure your upflush toilet continues to function efficiently.
