How to Detect a Silent Toilet Leak

The nuisance of a silent toilet leak is that it may waste gallons of water without your knowledge. If leaking, your toilet may waste more water than a dripping shower and faucet combined. So, what is the best method to detect a silent leak and stop it dead in its tracks?

As with any detection, toilet leaks start with an observation. You may see a water patch at the toilet bowl's base or run into a problem while flashing. Wait no more - that is your cue to use any of the following methods to detect a toilet leak.

Install a Water Leak Sensor
Water leak sensors are among the surest way to determine if a silent toilet leak exists or not. You can buy the affordable sensor and install it between the fill valve and supply line as per the accompanying manual. If there is a silent leak, the gadget will flash red lights and beep continually. The absence of leaks triggers a green light.

Try the Dye Test
The dye test is the second cheapest way to detect a silent toilet leak. All you have to do is introduce a conspicuous color in your toilet tank. The dye may be a food color or the toilet leak detection tablets. Close the tank lid and wait for ten minutes. If the bowl water acquires a shade similar to that in the bowl, a toilet leak exists.

Try the Pencil Test
This test requires you to draw a line to mark your toilet tank's water level and shut off the water supply. Take a thirty-minute breather and brace yourself for the results. If the water level lowers or remains at the same position, a toilet leak exists.

Observe the Overflow Tube
A drip from the overflow tube is adequate proof that your toilet has a silent leak. A faulty fill valve that requires a plumber's attention may be the cause of the leak.
