What To Know

- Install the new flapper valve by hooking it onto the flush valve and adjusting the chain length so that the flapper sits properly on the valve seat.
A dripping toilet tank is a common household annoyance that can waste gallons of water and increase your utility bills. Understanding the causes behind this persistent problem is crucial for finding an effective solution. This comprehensive guide will delve into the reasons why your toilet tank might be dripping and provide step-by-step instructions on how to fix it.
Causes of a Dripping Toilet Tank
1. Worn-Out Flapper Valve
The flapper valve is a rubber seal that sits at the bottom of the tank and prevents water from flowing into the bowl when the toilet is not in use. Over time, the flapper can become worn, cracked, or misaligned, allowing water to leak into the bowl.
2. Faulty Fill Valve
The fill valve controls the water level in the tank. If the fill valve is malfunctioning, it may not shut off properly when the tank is full, causing water to overflow into the bowl.
3. Loose or Damaged Flush Valve
The flush valve is responsible for releasing water from the tank into the bowl when the toilet is flushed. If the flush valve is loose, it can allow water to leak into the bowl even when the toilet is not in use.
4. Corroded or Broken Tank Bolts
The tank bolts hold the tank to the toilet bowl. If the bolts become corroded or broken, they may no longer seal properly, allowing water to leak from the base of the tank.
5. Cracked Toilet Tank
In rare cases, the toilet tank itself may be cracked or damaged, allowing water to leak out. This is usually caused by excessive force or impact.

1. Replace the Flapper Valve
- Turn off the water supply to the toilet.
