Follow these expert tips to keep the toilet running efficiently and halt any needlessly wasted water, and reduce your water bill. Well let’s get right down to your ghost flushing problem.

Top Causes behind Your Toilet's Random Flushes

Just a couple of small components are all that separate the water in your tank from where it wants to be. They are so much the better, but if they get worn, or change position out of place, then the toilet refill it. These are some reasons that may be the cause of a random flushing of your toilet:
• Leaking flapper valve - allows water to slowly escape from the tank to the bowl
• Wrong setting of water level and over run in pipe
• Flapper chain or flush level issues, which interfere with correct sealing
• Refill tube shoved down too far in overflow pipe runs continuously
• Changes in water pressure that cause the fill valve to suddenly turn on
These problems are ...
... what lead to ghost flushing and water waste.

Faulty Fill Valve Issues

If there is a misadjusted or failing fill valve, water runs through it and cycles.
• What you hear: Hissing, gurgling or short explosions of refilling.
• What you find: The water level is above the marked line, or water trickles into the overflow.
• Fast checks: Raise the float softly. If the flow doesn't stop, the valve or float height needs adjusting. Check the float arm for a possible rub against the tank wall.
Worn Flapper Valve Leaks
The flapper is the rubber barrier at the bottom of the tank. Leaking occurs when it sets, warps or cracks.
• Signs: A silent drip, dye from a tank test appearing in the bowl or a chain that is too tight.
• Why it happens: Rubber begins to break down over time from minerals, cleaners, and age.
• Simple test: Drop food coloring into the tank, wait 15 minutes; don’t flush. If there’s color in the bowl, it means the flapper leaks.

Easy Steps to Fix the Ghost Flushing Issue

• First off, turn off the water supply to your toilet, and then flush to empty the tank out - it's a good idea to make sure it's fully empty before moving on.
• Take a look at the flapper - If it's slimy, twisted, or just plain brittle, it's probably on its way out and times to get a new one - make sure you get one that matches your toilet model.
• Clean around the seat of the flapper - get all the mineral deposits off so that new flapper can fit snugly and do its job properly.
• Now have a look at the chain - make sure that new flapper has a bit of room to sit flat and get the job done. A quarter inch gap is a good starting point.
• Have a check on that float on the fill valve - the water level needs to be about an inch below the overflow tube.
• If your fill valve is stuck, give it a good clean or swap it for a new one if needs be. Changing most modern valves is a pretty quick and easy job.
• Now turn the water back on and have a listen - if you don't hear any hissing, dripping or ripples in the bowl you should be all good.

Remember to utmost care here - don't let wires or plugs get wet and if you're ever in doubt or see something looks broken just stop what you are doing.
