Seal underground return-line leaks in seconds, even when the break is deeper in the line. The 14" Frankenplug slides into a broken or cracked 1.5" return fitting, then expands to seal both the threads and the pipe beyond the break. A built-in 0.75" flow-through tube maintains circulation immediately—no excavation, no costly replacements.

Why the 14" model

• Extended reach to bypass damage farther past the wall fitting.

• Same fast, dual-seal performance—just designed for deeper or recessed breaks.

Fast, Reliable Repair

• Insert, tighten, done—typical installs take under 15 seconds.

• Expanding design creates a dual seal: in the fitting’s threads and in the downstream pipe.

• Restores flow via the ¾" internal open pipe that runs through both seals.

Where it’s used

• Underground return fittings on 1.5" pool plumbing (common PVC return lines).

Features

• 14" overall length (extended-reach design)

• Repairs typical underground leaks in < 15 seconds

• Dual-seal design (threads + pipe beyond the break)

• 0.75" flow-through passage keeps water moving

• Simple, tool-assisted tightening for a secure set
