How to Fix a Running Toilet: A Simple Guide for Melbourne Homeowners
A running toilet can quietly waste thousands of litres of water each year and push your utility bills steadily upward. The good news is that most causes are simple to diagnose and repair in under an hour with a few basic tools.
Why Is My Toilet Running?
Water continuously trickles from the tank into the bowl when the flush mechanism fails to seal properly. The three most common culprits are a worn flapper, a faulty fill valve, and a misadjusted float that keeps the refill running non-stop.
Step 1: Check the Flapper
Lift the tank lid and inspect the rubber flapper at the base of the tank. If it looks warped, cracked or covered in mineral buildup, water will leak past it constantly. Replacing a flapper is a five-minute job — simply unhook the old one, snap a compatible new one into place, and test the flush.
Step 2: Adjust the Fill Valve
If you hear water hissing after the tank is full, the fill valve may not be shutting off completely. Many fill valves have an adjustment screw or dial that lets you lower the water level. Turn it down until the water stops about 10mm below the overflow tube.
Step 3: Inspect the Flush Handle and Chain
A chain that is too long can snag under the flapper and hold it open. Trim or reposition it so there is just enough slack for a full flush. If the handle feels loose, tightening the mounting nut usually resolves it.
When to Call a Professional
If your toilet still runs after these checks, or you notice the tank refilling constantly, you may have a more complex issue with the valve seat or supply line. Our licensed plumbers can pinpoint the problem quickly. Contact Prizesvector for fast, affordable assistance across Melbourne.
