6. Troubleshooting

This section addresses common issues you might encounter with your toilet.

6.1 Toilet Not Flushing or Weak Flush

• Check Water Supply: Ensure the water supply valve behind the toilet is fully open.
• Inspect Trip Lever: Verify the right-hand trip lever is properly connected to the flapper chain inside the tank. Adjust the chain if it's too loose or too tight.
• Examine Flapper: Check if the flapper is sealing correctly at the bottom of the tank. Mineral buildup or wear can prevent a good seal.
• Water Level: Ensure the water level in the tank is at the recommended fill line. Adjust the fill valve if necessary.

6.2 Loose Toilet Seat

• If the seat becomes loose, gently remove the quick-release seat.
• Tighten the mounting bolts that secure the seat hinges to the toilet bowl. Do not overtighten.
• Reattach the quick-release seat.

6.3 Leaks

• Base Leaks: Check the wax ring and flange bolts. If leaking from the base, the wax ring may need replacement or the bolts may need tightening.
• Tank-to-Bowl Leaks: Ensure the tank-to-bowl bolts are tight and the gasket is properly seated.
• Supply Line Leaks: Check the connection of the water supply line to the fill valve and the wall. Tighten connections if necessary.
