Hi All,

Is Plumber's Putty drinking water safe, or should you
only use it on waste water lines?

Many thanks,

exhaust line of my swamp cooler, which is giving me a bad time with
a slow leak. My concern was if something toxic got mixed into
the water and then got blown all over the house.

Aquarium sealant?
