4. Setup and Installation
This section outlines the general steps for installing your SANIFLO toilet tank. It is recommended to consult a qualified plumber for professional installation to ensure compliance with local codes and optimal performance.
4.1. Before You Begin
- Ensure all necessary tools and materials are available.
- Turn off the main water supply to the bathroom.
- Remove the old toilet tank if replacing an existing unit. Clean the area thoroughly.
- Inspect the new SANIFLO tank for any visible damage before installation.
4.2. Installation Steps
- Position the Tank: Carefully place the SANIFLO toilet tank onto the back of the toilet bowl, aligning the bolt holes.
- Secure the Tank: Insert the provided bowl screws through the tank and bowl holes. Secure with washers and wing nuts from underneath the bowl. Tighten evenly to prevent cracking the vitreous china, but do not overtighten.
- Connect Water Supply: Attach the water supply line to the fill valve on the underside of the tank. Ensure a watertight connection using appropriate plumbing tape or sealant if necessary.
- Install Flush Lever: Attach the flush lever to the tank, connecting it to the flush valve mechanism inside. Ensure smooth operation.
- Restore Water Supply: Slowly turn on the main water supply. Check for any leaks around the connections. Allow the tank to fill.
- Test Flush: Perform several test flushes to ensure proper operation of the fill valve, flush valve, and water level. Adjust the fill valve if the water level is not at the marked line.

5. Operation
The SANIFLO toilet tank operates by storing water for flushing and releasing it into the toilet bowl when the flush lever is activated. The internal mechanisms are designed for efficient water usage and reliable performance.
5.1. Flushing
- To flush, press down firmly on the flush lever located on the side of the tank.
- The flush valve will open, allowing water to flow from the tank into the bowl, initiating the flush cycle.
- Once the flush is complete, the flush valve will close, and the fill valve will begin refilling the tank to the appropriate water level.
5.2. Water Level
The tank is designed to refill to a specific water level, indicated by a mark on the overflow tube. This ensures optimal flushing performance and water conservation (1.6 GPF). If the water level is consistently too low or too high, adjustments to the fill valve may be necessary.
6. Maintenance
Regular maintenance helps ensure the longevity and efficient operation of your SANIFLO toilet tank.
6.1. Cleaning
- Exterior Cleaning: Clean the exterior of the vitreous china tank with a soft cloth and mild, non-abrasive cleaner. Avoid harsh chemicals that could damage the finish.
- Interior Cleaning: It is recommended to not use harsh cleaning ingredients or in-tank cleaners. Products containing chlorine can damage the internal components, including the silicone flapper seal and fill valve.
- For internal cleaning, a soft brush and plain water or a mild, non-chlorine-based toilet bowl cleaner (applied directly to the bowl, not the tank) can be used.
6.2. Component Inspection
- Periodically inspect the fill valve and flush valve for wear or damage.
- Check the silicone flapper seal for proper seating and any signs of deterioration. Replace if necessary to prevent leaks.
- Ensure all connections, especially the water supply line, are secure and free of leaks.
7. Troubleshooting
This section addresses common issues you might encounter with your toilet tank. For problems not listed here, or if solutions do not resolve the issue, contact SANIFLO customer support or a qualified plumber.
| Problem | Possible Cause | Solution |
