App Concept

PinSeal Pro

PinSeal Pro is a spray-on or injectable sealant specifically designed for sealing pinhole leaks in inaccessible cast iron P-traps. Unlike putty, it can be applied remotely via a flexible applicator, cures to a durable epoxy-like finish, and buys years of time before replacement is needed. It's the first product purpose-built for this exact pain point.

Rapid-curing epoxy formula bonds to cast iron
Withstands water pressure and sewer gases
Non-toxic and safe for plumbing systems

Target Users: Plumbers and maintenance professionals dealing with hard-to-reach cast iron P-traps in residential and commercial buildings.
