Have a toilet leak?
If you think you might have a leak in your toilet here is how you can check.
1. Remove the TANK lid.
2. Put 5-10 drops of food coloring in the TANK. Put lid back on but don't flush it.
3. After about 10 minutes, look in the BOWL. If you see color, you have a leak.
The main causes of a leak are either a "fill valve" that will not shut off or a bad
"flapper".
Fill valve problem
A fill valve problem will cause water to flow over the "overflow tube", either
because the water level is set too high or it won't shut the water off. If you can't
adjust the water level lower or can't get the fill valve to shut off, replace the fill
valve. Pedestal fill valves are considered more reliable than the ball and float type.
Bad flapper
If you had water run into the bowl during the dye test and the water level is not
set too high, your flapper is probably leaking and it should be replaced. If your
old flapper has a float on the chain, make sure your new one does too (or put the
old float on the new chain).
When replacing a toilet flapper, remember that it is very important to replace it
with the proper flapper model for your toilet. Using a standard flapper in many
1.6 gallon toilets can make the toilet flush up to 3.5 gallons per flush (except
FlushStar models).
