@allbetterapp: Food coloring. Toilet tank. 15 minutes. That's the whole test. A toilet can leak for months without a drop on the floor, because the leak goes into the bowl. A worn flapper lets a thread of water past the seat, the tank level drops, the fill valve tops it off, and it can keep repeating day and night. A few drops of color in the tank, no flush, wait 15 minutes. Color in the bowl means the flapper is leaking.
