Aqua Plugs: The Most Versatile Solution for Irregular Fittings, Buried Ports, and Light Pressure Testing

When it comes to leak detection and pool repair, having the right tools isn’t just convenient—it’s essential. That’s exactly why Aqua Plugs from LeakTronics have become a go-to solution for professionals who need reliability, adaptability, and performance in the field. Whether you’re dealing with odd-sized fittings, buried ports, or light pressure testing, Aqua Plugs deliver unmatched versatility that simplifies your workflow.

Built for Irregular and Non-Standard Fittings

Not every job presents you with a perfect, uniform fitting. In fact, many fittings are out of round, oversized from aging or corrosion, undersized from manufacturing variations, or simply irregular due to years of use. Traditional plugs rarely account for these inconsistencies.

Aqua Plugs are engineered specifically to grip and seal irregular fittings with confidence.

Their inflatable design expands evenly in all directions, allowing them to conform to imperfect shapes while maintaining a strong, uniform seal. This makes them ideal for:

• Odd-sized or non-standard fittings
• Aging or worn fittings that no longer match spec
• Variations caused by corrosion, mineral buildup, or manufacturing tolerances

You can choose the right size range for the job:

• Small Aqua Plugs (¾" to 1 ¼") – perfect for smaller lines and tight fittings.
• Medium Aqua Plugs (1 ¼" to 2") – the go-to plug for standard pool plumbing sizes.
• Large Aqua Plugs (2 ½" to 3") – built for larger lines and heavy-duty isolation.

If the opening isn’t perfect—Aqua Plugs make it workable.

Perfect for Fittings That Have Been Plastered Over

Anyone working in older pools knows the struggle: fittings that have been plastered over or buried beneath layers of finish. Trying to work around these conditions with standard plugs usually leads to poor seals, wasted time, and unnecessary frustration.

Aqua Plugs are different.

Their flexible, inflatable bodies can insert into partially obstructed openings and expand behind the plaster, forming a tight seal even when the face of the fitting is no longer accessible.

This makes them invaluable for:

• Skimmer throats and returns partially covered in plaster
• Old pool remodels where fittings were incorrectly buried
• Renovation environments where access is limited

With Aqua Plugs, you don’t need a perfect surface—just enough access to position the plug and inflate it into place.

Ready for Light Pressure Testing and Injection

Aqua Plugs don’t just block water—they also open the door for testing and controlled injection.

Each plug is equipped with a dedicated inflation valve and, when paired with injectors, gives techs a way to introduce air or water for light pressure testing, line confirmation, or leak detection without removing the plug. For maximum efficiency, match your plugs with the dedicated injectors:

• Medium Injector – designed to work with Medium Aqua Plugs (1 ¼" to 2") for controlled air injection.
• Large Injector – built for use with Large Aqua Plugs (2 ½" to 3") on bigger lines.

That means you can:

• Seal a fitting and test from the same point
• Perform low-pressure checks without cumbersome adapters
• Inject water or dye for targeted leak tracking
• Confirm line isolation instantly and accurately

Always follow safety guidelines: Aqua Plugs are designed for static and low-pressure testing. Never exceed 10 PSI when pressure testing, and only use them in conditions where a plug failure will not cause injury or damage.

For technicians who want multi-function capability in a single tool, Aqua Plugs deliver exactly that.

A Tool Designed for Real-World Job Conditions

In the field, perfection is rare—and adaptable tools win. Aqua Plugs are built to handle situations that traditional plugs simply can’t, providing:

• A secure seal in imperfect or obstructed openings
• A way to inject or test without swapping equipment
• Durability to withstand frequent, real-world use
• Tight sealing performance across a wide range of conditions

From leak detection techs to repair specialists, Aqua Plugs are quickly becoming an essential part of every pro’s truck. If you want one kit that covers everything, the Master Aqua Plug Kit includes small, medium, and large Aqua Plugs, injectors, testing cones, and a pressure rig—so you’re ready for any pool plumbing layout you run into.

Build a Complete Plug and Testing Setup

Aqua Plugs work even better as part of a complete plug and testing system. Alongside the dedicated Aqua Plug lineup, LeakTronics also offers a full range of plug kits and accessories for pool, spa, plumbing, and irrigation work.

Use Aqua Plugs to:

• Isolate lines before pressure or vacuum testing
• Support leak detection with listening equipment and cameras
• Prepare plumbing for trenchless repairs and targeted fixes

Pair Aqua Plugs with LeakTronics leak detection kits and inspection tools to create a fast, repeatable workflow that lets you diagnose the problem, show your customer the issue, and move straight into repair.

Why Aqua Plugs Belong in Every Pro’s Truck

If you’re working on pools, spas, or small-diameter plumbing, Aqua Plugs solve problems traditional plugs just can’t touch. They’re especially valuable when you’re dealing with:

• Irregular or out-of-round fittings
• Plastered-over or partially buried ports
• Light pressure testing and injection from one access point
• Mixed plumbing sizes across one job site

Instead of fighting your plugs—or walking away from questionable fittings—you can seal, test, and confirm with confidence.

For a simple, scalable solution, start with the size range you use most. For an all-in-one answer that covers almost everything you’ll see in the field, step up to the Master Aqua Plug Kit and keep every Aqua Plug you need in one organized, professional package.

When the fittings aren’t perfect, the plaster isn’t clean, and the specs don’t match the real world, Aqua Plugs give you the control, seal, and flexibility to get the job done right.
