Cleaner Smoke.
Smarter Smoke Testing.
The Blowfish F2 Plumbing Smoke Blower represents a fundamental advancement in professional smoke testing. Designed for residential and commercial building plumbing and sewer laterals, the F2 pairs powerful airflow with continuous, dense, water-based smoke—moving far beyond the limitations of traditional pellet-based systems. The result is a next-generation smoke testing solution that is cleaner, safer and more effective.
Instead of burning pellets, the patent-pending F2 uses F-Series water-based smoke fluid to produce dense, highly visible smoke with minimal odor. This cleaner smoke profile makes the F2 especially well-suited for smoke testing in occupied buildings or areas with sensitive interiors or inventories such as restaurants.
The F2 delivers continuous smoke output with no burn time to manage and no pellets to reload, allowing plumbers to perform extended tests and inspect large systems, complex layouts or multiple problem areas in a single setup. An optional remote control further enhances efficiency, enabling operators to initiate smoke from the inspection area—an advantage for solo plumbers and large job sites alike.
Made and designed in the USA, the Blowfish F2 Plumbing Smoke Blower sets the new benchmark for professional smoke testing. With features and functionality unmatched by conventional systems, it provides cleaner operation, safer interior use, and a more effective approach to modern plumbing leak detection.
The F2 operates on Blowfish F-Series Smoke Fluid only.

The Right Connection.
Every Time.
The Blowfish F2 includes a blower hose equipped with a threaded Cleanout Adapter, allowing for leak-free smoke delivery. The hose connects to the blower using a quick-attach fitting, making setup fast and straightforward. On the business end, the 4-in-1 Cleanout Adapter threads directly into common plumbing cleanout sizes, creating a secure, leak-free connection. No duct tape or improvised fittings—thread it in and begin testing.
The adapter also includes an internal anchor point for direct connection to Blowfish Pipe Plugs. This keeps the entire setup contained within the system, helping prevent lost plugs while maintaining a sealed connection. The hose itself is lightweight, flexible, and easy to position. It extends to a full 10 feet during use, then compresses down for compact storage. The result is a setup that stays clean, controlled, and easy to manage from start to finish.

F2 Smoke Blower FAQ
Is the F2 safe to use indoors?
Yes. The F2 is by far the industry’s best solution for situations that require a smoke blower to be positioned indoors. Its sealed design and water-based fluid produce dense, highly visible smoke with a very mild, low-odor profile, making it exceptionally well suited for finished interiors and environments with sensitive contents. Always be sure to follow proper Smoke Test Procedures, especially when setting up a smoke blower inside.
What makes the F2 different from pellet-based smoke blowers?
The F2 operates on water-based smoke fluid rather than traditional smoke pellets. This provides a cleaner, lower odor smoke. The F2 platform also allows for continuous smoke output and has advanced features like remote control.
Can the F2 handle large commercial or complex plumbing systems?
Yes. The F2 is an excellent choice for testing multi-story and larger plumbing systems. Its continuous output allows for steady, uninterrupted smoke production, which is especially helpful when working through extensive piping layouts. On very large structures, dividing the system into sections with pipe plugs or relocating the blower as needed remains the most efficient approach.
What maintenance does the F2 require?
The F2 is designed for repeat use with minimal routine upkeep. Standard care includes basic inspection and proper storage. We recommend running the machine at least once every couple months. We also recommend doing a basic clean procedure every 3 years.
Is service and technical support available?
Absolutely. The F2 is backed by a comprehensive warranty and U.S.-based service support. In the event of an issue, diagnostics, parts, and repairs are handled directly by the same team responsible for engineering and manufacturing Blowfish equipment, ensuring knowledgeable and efficient support.

What Is Plumbing Smoke Testing?
Plumbing smoke testing is a proven diagnostic technique used to locate leaks, faulty connections, and defects within building plumbing systems. By introducing smoke and calibrated airflow into plumbing, technicians can immediately identify escape points—revealing cracked pipes, improper fittings, and other concealed failures that often go undetected with cameras and other inspection techniques.
Smoke testing is commonly performed in residential homes, commercial buildings, and sewer lateral inspections because it delivers rapid, visual confirmation of plumbing system integrity without unnecessary demolition. When conducted properly with the right equipment, the process is controlled, efficient, and highly effective for pinpointing air leaks and odor sources.
