Setup and Installation
This section outlines the general steps for installing your TOTO MS853113E toilet. A 12-inch rough-in is required for proper installation. Top-tightening mounting bolts are included for ease of installation.
Required Tools (Not Included):
- Adjustable Wrench
- Screwdriver
- Putty Knife
- Tape Measure
- Level
- Wax Ring with Flange
- Flexible Water Supply Line
Installation Steps:
- Prepare the Area: Ensure the floor flange is clean and free of debris. Remove any old wax ring material.
- Install Flange Bolts: Insert the T-bolts into the floor flange slots and secure them with washers and nuts, ensuring they are upright and parallel to the wall.
- Set the Wax Ring: Place the new wax ring onto the horn of the toilet bowl or directly onto the floor flange, ensuring a good seal.
- Position the Toilet: Carefully lift the toilet and align the bolt holes in the base with the T-bolts. Gently lower the toilet onto the wax ring, pressing down firmly and evenly to create a watertight seal. Do not rock the toilet.
- Secure the Toilet: Place washers and nuts onto the T-bolts. Hand-tighten the nuts, then use a wrench to tighten them incrementally, alternating between bolts to ensure even pressure. Do not overtighten, as this can crack the ceramic.
- Connect Water Supply: Attach the flexible water supply line from the shut-off valve to the toilet's fill valve connection. Hand-tighten, then use a wrench for a final snug turn. Do not overtighten.
- Restore Water Supply: Slowly turn on the main water supply and check for leaks at all connections. Allow the tank to fill.
- Install SoftClose Seat: Follow the separate instructions provided with the SoftClose seat for proper attachment to the toilet bowl. The top-tightening design simplifies this process.

Operating Instructions
Flushing the Toilet:
To flush the toilet, press down firmly on the chrome trip lever located on the left side of the tank. The E-Max flushing system will initiate a powerful siphon jet action, clearing the bowl efficiently with 1.28 gallons of water. Release the lever once flushing is complete.

Using the SoftClose® Seat:
The TOTO SoftClose® seat is designed to lower gently and quietly, preventing slamming. To close the seat or lid, simply push it down slightly and release. The built-in hinge system will control the descent, ensuring a soft closure.
Maintenance
Regular cleaning and maintenance will ensure the longevity and optimal performance of your TOTO toilet.
Cleaning the Toilet:
- Exterior: The one-piece design eliminates crevices, making the exterior easier to clean. Use a soft cloth and a mild, non-abrasive bathroom cleaner. Wipe down all ceramic surfaces, including the tank, bowl exterior, and base.
- Interior Bowl: Use a toilet brush and a non-abrasive toilet bowl cleaner. Apply cleaner, let it sit for the recommended time, then scrub thoroughly and flush.
- SoftClose® Seat: Clean the seat and lid with a soft cloth and mild soap and water. Avoid harsh chemicals or abrasive cleaners, as these can damage the finish and the SoftClose mechanism.
- Chrome Trip Lever: Wipe with a soft, damp cloth. Avoid abrasive cleaners that can scratch the chrome finish.
General Maintenance Tips:
- Periodically check the water supply line connection for any signs of leaks.
- Ensure the tank cover is properly seated to prevent foreign objects from falling into the tank mechanism.

Troubleshooting
This section addresses common issues you might encounter with your toilet.
| Problem | Possible Cause | Solution |
|---|
| Weak Flush / Multiple Flushes Required | Low water level in tank; obstructed trapway; faulty flush valve seal. | Check water level and adjust if necessary. Inspect the trapway for blockages. Examine the flush valve seal for wear or debris. |
| Continuous Running Water | Fill valve not shutting off; flush valve seal not seating properly. | Check the fill valve for proper operation and adjustment. Inspect the flush valve seal for debris or damage and replace if needed. |
| Leaking at Base | Improperly seated wax ring; loose mounting bolts; cracked ceramic. | Tighten mounting bolts evenly (do not overtighten). If leaking persists, the wax ring may need replacement. Inspect for ceramic cracks. |
| Noisy Operation (e.g., Water Hammer) | Faulty fill valve; high water pressure. | Inspect or replace the fill valve. Consider installing a water hammer arrestor if the issue persists and is related to water pressure. |
