Damaged flappers can leak water undetected down your drain. Simply place Niagara’s Leak Detection Dye Tablets into your toilets tank, and if blue water appears in your bowl, you have a damaged flapper that needs to be replaced. Niagara’s Dye Tablets are non-toxic and include easy to follow bi-lingual directions.


  • Tablets contain only FDA-certified, non-toxic, non-carcinogenic pigments – not harmful if swallowed.
  • Easy to follow instructions, printed in both English and Spanish
  • Packaged in moisture-resistant packs
