HOW DO YOU KNOW IF YOUR TOILET IS LEAKING?

Toilets are one of the most common sources of leaks in the home, usually unnoticed by the residents because the leaks are often silent and out of view. Most toilet leaks will send the waste water directly into the sewer line without detection by residents. Several research studies have found 20% to 35% of all residential toilets leak to some degree. These leaks, if undetected and/or unattended, can cause a significant price increase in ones water bill.

Large toilet leaks can be detected when the valve constantly emits a hissing or gurgling sound when the toilet is not in use. Smaller, though significant, leaks require further investigation. Removing the tank lid to inspect the flush mechanisms is the first step.

The water level in the tank should be no higher than 1-inch below the top of the overflow tube. Some tanks require a lower water level, but are never higher than 1-inch. If the water level is to the very top of the overflow tube, water is slowly leaking into the overflow tube and down into the drain. The problem has one of three causes:

1. The water level is adjusted too high.
2. The float is damaged and not shutting off the refill valve.
3. The refill valve (ball-cock assembly) is worn and needs replacement.

Performing a dye test will allow detection of leaks in the flapper valve. Test procedures include placing dye tablets into the tank water which causes the water to turn dark blue. If the dark blue water appears in the bowl within 15 minutes, there is a leak in the flapper valve.

There are several causes for these leaks, but flapper valves are the most common problem. The flapper provides the barrier that holds the water in the tank until the user activates the flush handle by pulling on the chain attached to the flapper valve. When the flapper is raised, the water in the tank rushes into the bowl creating the flush. After the flush is complete, the flapper falls back down onto the valve seat to retain the water as the tank refills. Leaks occur when the flapper valve does not create a watertight seal. The seal can be compromised due to several reasons:

1. The most common cause is due to a worn or warped flapper.
2. The chain could be snagging resulting in the flapper not able to drop completely onto the valve seat.
3. The valve seat is worn.
