Common Causes of Constant Toilet Water Flow

1. Worn-Out Flapper Valve

The toilet flapper is a rubber seal that controls water flow from the tank into the bowl. Over time, it can wear out, crack, or warp—causing water to leak constantly from the tank to the bowl.

Symptoms:

• Toilet refills frequently

• Constant running sound

• Jiggling the handle temporarily stops the noise

2. Float Issues

The float controls the water level in the tank. If the float is set too high, the tank will keep filling and draining through the overflow tube.

Symptoms:

• Overflow tube is always draining

• Water spills into bowl frequently

• High water level inside the tank

3. Faulty Fill Valve

The fill valve brings water into the tank after every flush. If it’s defective or misaligned, it can cause continuous water flow.

Symptoms:

• Noisy or slow filling

• Overflowing tank

• Constant water trickling sound

4. Chain Problems

If the chain connecting the handle to the flapper is too short or tangled, it may prevent the flapper from sealing properly.

Symptoms:

• Handle feels loose

• Flapper doesn’t close all the way

• Constant trickling sound

Step-by-Step Fixes to Stop Constant Toilet Water Flow

✅ Step 1: Inspect the Flapper

• Turn off the water supply to the toilet.

• Flush the toilet to empty the tank.

• Inspect the flapper at the bottom of the tank.

• If it looks warped or brittle, replace it with a new one (costs around $5–$10).

• Ensure the chain isn’t too tight or too loose.

✅ Step 2: Adjust or Replace the Float

• Look for a float ball or cup-style float.

• Adjust the float to lower the tank water level (usually a screw adjustment or clip).

• If the float doesn’t respond or appears damaged, replace the fill valve and float assembly.

✅ Step 3: Replace the Fill Valve

• Shut off the water and drain the tank.

• Unscrew the old fill valve using pliers.

• Install a new adjustable fill valve (cost: $10–$25).

• Connect the refill tube and turn water back on to test.

Bonus Tips from a Good Plumbing Service Co

• Use food coloring to detect hidden leaks. Add a few drops to the tank. If color appears in the bowl without flushing, your flapper is leaking.

• Flush your toilet monthly if unused for long periods. Stagnant water wears out the rubber parts.

• Check water pressure. High water pressure wears out valves and flappers faster.

Need help? A good plumbing service co can handle full toilet replacements, valve repairs, and system inspections.
