Here’s a comprehensive look at what’s amiss with your toilet and how to fix it.
1. Gasket Leakage
Kohler Aqapiston toilets feature rubber gaskets that wear out with time.
They will start leaking around the base of the toilet bowl as they deteriorate. It can result in floor stains and even mold growth in damp environments such as basements.
To resolve this issue, replace the gaskets with new ones purchased from a local hardware shop or hire a plumber.
2. Excess Water Usage
Many households are attempting to reduce their water consumption by using low-flow toilets. Unfortunately, a Kohler Aquapiston toilet may consume up to twice the amount as other toilets.
Therefore, Aquapiston will easily take your water bill through the rooftop.
Adjust the water level in the tank.
3. Problematic Filling Mechanism
Another issue with Kohler Aquapiston is that the fill valve does not close well after flushing. It implies that if you try to refill the tank with water, it will keep running until you cut off the water supply at the source.
- Get a new fill valve from a plumbing supply store or local hardware store. This procedure is simple, and you can DIY it without problems.
- If you’re not confident doing this work yourself, you should hire a plumber.
4. Kohler Aquapiston Not Flushing
Gravity flush woes are another prevalent issue with this model. Gravity flushing happens when insufficient water in the tank cannot provide enough pressure for appropriate flushing activity. It can stem from low water levels or other issues, such as obstructions.
If the Kohler Aquapiston toilet does not flush after use, check whether the fill or flapper valve is faulty.
Consider replacing the fill valve or the flapper valve if they are defective. Alternatively, adjust them if they are worn out from long service.
5. Weak Flush
Weak flushing is a pretty common issue with Kohler Aquapiston toilets. The flush system depends on a chain that needs to pull a rubber flapper closed over the drain opening.
The chain might stretch and loosen with time, leading to a weak flush.
To fix this issue, replace the flush chain with a new one, available at most hardware stores.
6. Leaky Flapper Valve Seal
When you flush your Kohler Aquapiston toilet, the flapper valve rises to let water into the bowl. Leaks can occur when the rubber seal surrounding this valve wears or cracks.
- Cut off the water supply and lift the tank cover.
- After that, you’ll remove the old flapper, clean any dirt from the valve seat, and replace it.
7. Challenges With Installation
Installing these toilets in your house or place of business might be one of the most frustrating aspects of utilizing them because they differ from standard toilets in design.
- If you are experiencing issues with your Kohler Aquapiston, you should first determine whether you installed it correctly. For the flushing mechanism to function optimally, your toilet must be level and plumbed according to the manufacturer’s instructions.
- The flushing system won’t operate as it should if your toilet is set up unevenly or doesn’t have an adequate water supply.
Kohler Aquapiston Not Filling
If water enters your Kohler Aquapiston toilet but does not fill it, the issue is with the float valve or fill valve. Here is how to fix it:
a) Flushing The Fill Valve
- Shut the water, flush your toilet, and take out the tank cover.
- Grasp the fill valve shaft at the base and undo it by rotating it 1/8th of a turn anticlockwise.
- Examine the fill valve for dirt and clean it if necessary.
- Position a cup upside-down over the valve to stop water from splashing.
- Turn on the water supply and allow the water pressure to wash the trash down the toilet.
- Reinstall the fill valve and tighten it clockwise.
b) Adjust The Float
- Shut off the water, flush your Aquapiston, and take the tank cover off.
- When the float arm joins the fill valve, turn the screwdriver in a clockwise direction if you’re using a ball float.
- Use a screwdriver anticlockwise on the plastic screw next to the float.
- Before adding water to the toilet tank, readjust the float into smaller amounts. About half an inch should remain in the tank above the overflow tube.
- Replace the tank lid.
Kohler Aquapiston Review (How Does it Work?)
The Aquapiston flush from Kohler is a robust built-in flushing innovation. It turns water 360 degrees to produce a more forceful flush while using less water.
Aquapiston is a flushing technology that uses a gravity-fed device. It boasts a rim’s edge represented by two large nozzles.
Water flows through the nozzles when you flush the toilet, creating cyclonic pressure that removes all waste at gravitational force.
The most remarkable aspect of Aquapiston is that it is one piece.
