3. Attach the Tankless Toilet to the Floor 

Place the toilet over the flange, aligning the mounting holes. Secure it to the floor utilizing screws or bolts.  

4. Installing the Wax Ring 

Carefully place the wax ring on the flange, ensuring a proper seal between the toilet and the drainpipe.

Post Installation Steps

1. Inspect for Leaks: After installing the tankless toilet, carefully inspect all connections, including the water supply line and flushometer valve (if applicable), for any signs of leaks. Address any leaks promptly to prevent water damage.
2. Test Flush Functionality: Flush the toilet several times to ensure that it operates smoothly and effectively. Pay attention to the strength and consistency of the flush and make any necessary adjustments to the flushometer valve or water pressure.
3. Check Stability and Alignment: Ensure that the tankless toilet is securely anchored to the floor and does not wobble. Adjust the bolts at the base if needed to achieve stability. Additionally, check the alignment of the toilet with the wall and adjust if necessary for aesthetic purposes.
4. Clean Up: Clean up any debris or excess materials left from the installation process. Wipe down the exterior of the toilet with a mild cleaner to remove any fingerprints or smudges.
5. Inspect Surrounding Area: Inspect the area around the tankless toilet for any damage or water leakage. Check for water pooling on the floor or signs of moisture on walls or baseboards. Address any issues promptly to prevent further damage.
6. Test Additional Features (if applicable): If your tankless toilet includes additional features such as a bidet function or automatic flush sensor, test these features to ensure they are functioning properly. Refer to the manufacturer's instructions for guidance on testing and adjusting these features.
7. Educate Users: Provide instructions to household members or users on how to operate the tankless toilet properly. Include information on flushing techniques, maintenance requirements, and any special features or functions.
