4. Setup and Installation
The PROFLO PF1501 Calhoun Elongated Toilet Bowl is designed for floor-mounted installation. For detailed, step-by-step installation instructions, please refer to the official Installation Manual PDF provided by PROFLO. This document contains critical diagrams and specific procedures for a successful setup.
Key Installation Considerations:
- Bowl-Only Configuration: This product is the toilet bowl only. You will need to select and install a compatible toilet tank and toilet seat separately.
- Floor Mounted: Ensure your plumbing rough-in is suitable for a standard floor-mounted toilet bowl.
- Elongated Design: The elongated bowl extends approximately 1-1/2 inches further than a round bowl, providing enhanced comfort. Account for this dimension in your bathroom layout.
Important: Always use a new wax ring or equivalent sealing gasket for installation to prevent leaks. Secure the bowl firmly to the floor flange using the provided bolts (typically included with the tank or a universal installation kit).

5. Operation
The PROFLO PF1501 Calhoun Elongated Toilet Bowl functions as the receptacle for waste. Its operation is directly linked to the toilet tank and flushing mechanism that you install with it. Once properly installed with a compatible tank and seat, the toilet operates by flushing water from the tank through the bowl to clear its contents into the drainage system.
The elongated design offers increased comfort compared to standard round bowls.
6. Maintenance
Regular cleaning and maintenance will ensure the longevity and hygiene of your toilet bowl.
- Cleaning: Clean the vitreous china surface regularly with a soft cloth, sponge, and a non-abrasive bathroom cleaner. Avoid harsh chemicals, abrasive scrubbers, or scouring powders, as these can damage the finish.
- Inspections: Periodically check the connection points between the bowl and the floor, and between the bowl and the tank, for any signs of leaks. Tighten bolts if necessary, but do not overtighten.
- Drainage: Ensure the drain is clear of obstructions. If clogs occur, use a toilet plunger or a plumbing snake designed for toilets.
7. Troubleshooting
This section addresses common issues related to the toilet bowl itself. For issues related to flushing mechanisms, water supply, or tank components, refer to the manual for your specific toilet tank.
- Issue: Water leaking from the base of the toilet bowl.
- Possible Cause: Loose floor bolts or a faulty wax ring.
- Solution: Gently tighten the floor bolts. If the leak persists, the wax ring may need to be replaced. This requires removing the toilet bowl.
- Issue: Toilet bowl wobbles.
- Possible Cause: Uneven floor or loose floor bolts.
- Solution: Ensure the floor bolts are securely tightened. If the floor is uneven, shims can be placed under the base of the toilet to stabilize it.
- Issue: Persistent odors around the toilet base.
- Possible Cause: Compromised wax ring seal.
- Solution: A faulty wax ring can allow sewer gases to escape. Replacement of the wax ring is necessary.
