Toilet Tank Leaking: 5 Causes and How to Fix

Why Is Your Toilet Tank Leaking?

A leaking toilet tank wastes up to 200 liters per day. Here are the 5 most common causes and fixes.

1. Worn Flush Valve Seal

The rubber seal deforms over time. Replace it — costs about 30-80 UAH.

2. Faulty Float Mechanism

Adjust the float height or replace the mechanism.

3. Cracked Overflow Tube

Replace the tube or entire flush mechanism.

4. Loose Tank Bolts

Tighten bolts or replace gaskets.

5. Condensation

Not a leak — it's moisture from temperature difference.
