Drug Testing & Toilet Leak Testing


Bluing tablets have a number of uses. The tablets can be used to detect leaks in flapper or ball valves. A tablet is placed in the toilet tank and if the valve is defective, the bowl will turn blue.

Plumbers use the dye tablets for testing customers’ toilets for leaks. Municipalities often tell home owners to test their own toilets for water conservation.

The tablets are also used for drug testing collections. A tablet is placed in the toilet tank and bowl so as to prevent water from being used to dilute their sample. Clinical laboratories around the country use our product.

Our bluing dye tablets turn the water a vibrant blue color. They dissolve in a minute or two as they effervesce, spreading dye in the bowl — if there’s a leak.
