Water is leaking from my toilet tank into the bowl
ISSUE:  A trickle of water is leaking down the back of the toilet bowl when the toilet is not being flushed.  

 Let's Identify the problem.

There are two main valves inside your tank that could be responsible:

  1. Inlet (Fill) Valve – Controls water coming into the tank.

  2. Outlet (Flush) Valve – Allows water to leave the tank during a flush.

 

Cause #1-Inlet Valve Issues: 

Signs:

  • Water level in tank is above the fill line (the mark inside your tank showing the proper water level)
  • Water is escaping into the overflow tube (small vertical pipe connected to outlet valve)

Why it happens: 

  • Debris is stuck inside valve → prevents it from shutting off.

  • Worn seals → valve doesn’t fully close, water keeps running.

Solution:

  • If toilet is newer or there’s been recent construction/storms/flooding in your area, try cleaning the inlet valve: (these conditions increase the amount of debris present in incoming water, which makes the presence of debris in your tank/valves more likely.)

    1. Shut off water supply.

    2. Remove inlet valve.

    3. Soak in 50/50 vinegar-water solution for 10 minutes.

    4. Rinse, repeat if needed, reinstall.

  • If toilet is older or in hard-water areas, replace seals (every 2–3 years) or replace the entire inlet valve head.

Cause #2: Outlet (Flush) Valve Issue

Signs:

  • Water level is normal (at the fill line).

  • Still see a slow trickle into the bowl.

Why it happens:

  • The seal at the bottom of the flush valve has worn down or cracked.

  • More common with hard water or if you’ve used in-tank chemical cleaners. (Note: in-tank cleaners should never be used. They can void your warranty.)

Solution:

  • Replace the flush valve seal (standard toilet maintenance every couple of years).

  • Easy DIY part swap—specific replacement part depends on your toilet model.
