Fitting Saver Repair System 4" (“Frankenplug”) — for 1.5" Pool Plumbing

Fix underground return-line leaks in seconds. The 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 keeps water moving, so circulation is restored immediately—no excavation, no costly replacements.

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.

Long-Term Fix

• Engineered for durable, underground use on return fittings that are cracked, stripped, or broken.

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

Where it’s used

• Underground return fittings on 1.5" pool plumbing (PVC/most standard return lines).

Features

• 4" overall length

• Repairs typical underground leaks in < 15 seconds

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

• 0.75" flow-through passage maintains water movement

• Simple, tool-assisted tightening for a secure set

How to Use

1. Locate the failed return fitting and ensure the line is accessible from the pool wall.

2. Insert the Frankenplug fully into the broken fitting.

3. Tighten until snug to expand the seals.

4. Verify flow through the ¾" passage and check for leaks.
