Persistent Flushing: Why Does My Push Button Toilet Keep Flushing?
What To Know
- A faulty fill valve may overfill the tank, causing the excess water to overflow into the bowl and trigger the flush mechanism.
- Turn off the water supply to the toilet and open the flush valve to drain the water from the tank.
- If the water level in the tank is too high or too low, or if the toilet keeps overflowing, it’s likely that the fill valve is malfunctioning.
Push button toilets, a common fixture in modern bathrooms, offer convenience and efficiency. However, when these toilets malfunction and keep flushing uncontrollably, it can be a frustrating and perplexing problem. This blog post aims to shed light on the underlying causes of this persistent flushing issue and provide you with practical solutions to restore your toilet to its proper functionality.
Common Causes for Uncontrolled Flushing in Push Button Toilets
1. Faulty Fill Valve:
The fill valve is responsible for regulating the water level in the toilet tank. A faulty fill valve may overfill the tank, causing the excess water to overflow into the bowl and trigger the flush mechanism.
2. Worn-Out Flapper:
The flapper is a rubber seal that sits at the bottom of the toilet tank. When the push button is pressed, the flapper lifts, allowing water to flow into the bowl. A worn-out or damaged flapper may fail to seal properly, leading to a continuous flow of water and constant flushing.
3. Misaligned Flush Valve:
The flush valve is the mechanism that releases the water from the tank into the bowl. If the flush valve is misaligned, it may not close completely after the flush, resulting in a continuous leak and uncontrolled flushing.
4. Clogged Overflow Tube:
The overflow tube is a small tube located near the top of the toilet tank. It prevents water from overflowing if the fill valve fails. A clogged overflow tube can cause water to back up into the overflow tube and trigger the flush mechanism.
5. Faulty Push Button:
The push button is the mechanism that activates the flush valve. A faulty push button may malfunction and trigger the flush even when not pressed, leading to constant flushing.
6. Air in the Water Lines:
Air in the water lines can cause the fill valve to malfunction and overfill the tank, resulting in uncontrolled flushing.
7. Water Pressure Issues:
High water pressure can put excessive strain on the toilet’s components, causing leaks and uncontrolled flushing. Conversely, low water pressure may not provide enough force to properly close the flush valve, leading to a similar problem.
Troubleshooting and Repair Solutions
1. Adjust the Fill Valve:
If the fill valve is overfilling the tank, adjust the water level by turning the adjustment screw on the fill valve.
2. Replace the Flapper:
A worn-out flapper should be replaced with a new one. Make sure to select a flapper that is compatible with your toilet model.
3. Realign the Flush Valve:
Disconnect the water supply to the toilet and loosen the bolts holding the flush valve in place. Realign the flush valve and tighten the bolts.
4. Clean the Overflow Tube:
Use a wire or pipe cleaner to clear any clogs in the overflow tube.
5. Check the Push Button:
If the push button is malfunctioning, replace it with a new one.
6. Remove Air from Water Lines:
Turn off the water supply to the toilet and open the flush valve to drain the water from the tank. Turn the water supply back on and let the tank refill. This should remove any air from the water lines.
7. Adjust Water Pressure:
If the water pressure is too high or too low, contact a licensed plumber to adjust the pressure regulator.
