5 DIY Fixes for a Leaking Flush Tank
A leaking flush tank wastes 500+ litres per month — fix it yourself in under 30 minutes.
Check the Flapper Valve
Saves 200 L/dayLift the flush tank lid. If the rubber flapper is warped or worn, water keeps running. A new flapper costs ₹80–150 at any hardware store.
Food Coloring Test
Saves Quick detectionAdd a few drops of food color to the tank (without flushing). If color appears in the bowl within 15 minutes, your flapper is leaking.
Adjust the Float Ball
Saves 100 L/dayIf water keeps running after flushing, the float ball may be set too high. Bend the float arm slightly downward to reduce the refill level.
Tighten Fill Valve
Saves 150 L/dayA hissing sound after flushing means the fill valve seal is loose. Tighten the nut at the bottom of the tank. A new fill valve costs ₹200.
Dual-Flush Conversion
Saves 500 L/monthReplace your single-flush mechanism with a dual-flush kit (₹400–600). Use half-flush for liquid waste — saves 3L every single use.
