1. Flushing Issues

American Standard Titan toilets are renowned for their efficient and powerful flushing, but you could still encounter flushing problems. This could involve weak flushing, incomplete flushing, or a toilet that won’t flush at all.

Flushing problems often arise from partial or complete clogging, low water level, faulty flapper or flush valve, mineral or debris buildup, flush handle issues, or damaged seals and gaskets. Checking these potential issues will help you understand and fix the problem.


  • Raise the water level in the tank by twisting the flat adjustment screw from left to right.
  • Dislodge any blockages with a plunger. If the clog persists, use a plumbing snake or auger to clear it.
  • Examine the flapper for damage. If it’s not sealing correctly, replace it with a compatible flapper. If your Titan toilet has a 2-inch flush valve, consider this durable and reliable American Standard 7381129-200.0070A Universal Flapper and Chain with Float (View on Amazon).
  • Also, clean the flush valve and the area around it to remove any buildup or debris affecting its operation.
  • Dissolve mineral deposits by soaking the affected parts in vinegar or a commercial cleaner, then scrubbing the buildup with a brush.
  • Ensure the flush handle is properly connected and not loose. Adjust or replace the handle if necessary. In addition, check the chain or lift arm attached to the flapper to ensure it has the right amount of slack for proper operation. Adjust accordingly.
  • Clear any blockages or obstructions in the vent pipe connected to the toilet.

2. Leaking

Even a tiny leak can cause massive water wastage over time, increasing water bills. It can also weaken structures, drive mold growth, and deteriorate toilet components.

Therefore, fix any leaking issues in your Titan toilet to avoid escalating the problem. Begin by finding out the origin of the leak, which includes around the base, tank, or even within the internal components.

The causes of leaking are a faulty flapper, loose connections, tank or bowl cracks, worn-out washers or bolts, and a faulty fill valve.


  • Add food coloring into the tank, and then watch if the colored water seeps into the bowl without flushing. If it does, you have a leaking flapper. Remove the damaged flapper and replace it with a new one.
  • Inspect the tank-to-bowl connections. Replace worn-out gaskets, washers, or bolts, making sure you tighten and secure them properly.
  • In addition, if necessary, check and adjust the the float or the fill valve.
  • Also, visually inspect the tank and bowl for visible damage or cracks that could cause a leak. You can replace the tank, bowl, or the entire unit.

3. Continuous Running

If the water in your American Standard Titan toilet tank runs into the bowl non-stop, it could be due to an improperly adjusted float, faulty flapper, or a defective fill valve. A leaky flush valve, debris or mineral buildup, or misaligned components might also cause this problem.

If the float is set too high, the water level might exceed the overflow tube, leading to continuous running as excess water spills into the bowl. Moreover, a faulty flapper won’t create a proper seal after flushing, allowing water to leak into the bowl continuously.

In addition, debris or mineral buildup in the fill valve can keep the flushing mechanism from functioning correctly. It is also essential to check for part alignment since your toilet’s flushing efficiency can be impacted by misalignment.


  • Inspect the flapper for damage, wear, or misalignment. Clean the sealing area and ensure it sits correctly on the flush valve seat. Replace a damaged flapper with a compatible replacement flapper.
  • Check the fill valve, ensuring it is not sticking. It should also shut off completely when the tank reaches the correct water level. If necessary, adjust the fill valve’s adjustment screw or mechanism.
  • Adjust the float to the appropriate position to set the water level.
  • Soak the fill valve, flush valve, or other parts within the tank in vinegar and brush them to remove mineral buildup or debris.
  • Replace any other damaged components.

4. Tank Filling Issues

Is your American Standard Titan toilet taking too long to fill, or is the water level in the tank insufficient? If so, troubleshoot your toilet for this issue by checking the fill valve for problems like a worn-out valve, debris blocking the valve, or improper adjustment.

Also, determine whether the shut-off valve is partially closed or your home’s water supply has low pressure. Furthermore, an improperly adjusted float might not signal the fill valve to shut off when the tank reaches the correct water level.

Moreover, mineral deposits or debris in the fill valve or water supply line can impede water flow, leading to slow or incomplete tank filling. The tank can also fill slowly or not reach the correct water level due to a malfunctioning flapper, triggering continuous filling as the fill valve tries to compensate.

Additionally, a faulty or stuck flush handle mechanism can cause filling problems.


  • Make sure the shut-off valve supplying water to the toilet is fully open and provides adequate water pressure.
  • Clean or replace the fill valve.
  • Adjust the float by bending the rod or adjusting the mechanism.
  • Replace your toilet’s flapper if it’s worn out or not creating a good seal.
  • Ensure the flush handle mechanism is functioning correctly and not sticking.
  • Use vinegar or a commercial cleaner to dissolve mineral deposits within the tank’s internal parts. After that, clean these parts thoroughly and flush the system before reassembling.

5. Clogging

This isn’t a common problem with American Standard Titan toilets because their flushing mechanisms are designed to reduce clogs and ensure efficient waste removal. However, this doesn’t mean you can’t clog your toilet if you misuse it by flushing items other than toilet paper and human waste, such as paper towels, hygiene products, or foreign objects.

Low water pressure or insufficient water flow also causes inefficient flushing that can cause clogging. Mineral deposits, especially in areas with hard water, can also accumulate in the toilet trapway or the drain pipe, narrowing the passage and causing clogs.

Furthermore, objects or waste can get stuck in the trapway or further down the drain pipe, obstructing the flow of water and leading to a clog.


  • Stop flushing your toilet once you find it clogged to avoid causing an overflow.
  • Dislodge the clog with a plunger. If the plunger doesn’t work, use a toilet auger because it is long enough to reach deep into the drain.
  • Alternatively, pour a toilet-specific drain cleaner or a mixture of hot water and dish soap into the toilet bowl and let it sit for some time to dissolve the clog.

How To Keep Your American Standard Titan Toilet From Clogging

  1. Avoid flushing anything other than toilet paper and human waste. The unflushables include paper towels, wipes, feminine hygiene products, or solid objects.
  2. Clean your toilet regularly to prevent buildup. Use mild cleaning agents or natural substances like baking soda to dissolve mineral deposits and prevent clogs caused by hard water buildup.
  3. Monitor water pressure and ensure proper water flow during flushing.
  4. Schedule periodic plumbing inspections or maintenance to check for any blockages or issues in the plumbing system that might lead to toilet clogs.
  5. Periodically check the toilet’s mechanisms, including the flush valve, fill valve, and flapper, to ensure they function correctly. Promptly replace damaged parts to maintain proper flushing efficiency.
