EWARP patch material cannot be used on ruptured pipes in which system?

• A. Potable water
• B. Fuel oil
• C. Sewage
• D. Compressed air

Answer: (A)

EWARP is a water-activated resin patch meant for a quick, temporary seal on pipe leaks without introducing fluids that could contaminate the system. It’s not approved for use on potable water lines because the resin and its additives could contaminate drinking water or introduce substances not suitable for human consumption. For this reason, you’d patch non-potable systems (like fuel oil, sewage, or compressed air) where fluid quality isn’t a concern, while potable water lines require other repair methods that keep drinking water safe.
