Is the P2 Smoke Blower safe for indoor use?

Yes. The P2 is the only pellet-based smoke blower that features a sealed smoke chamber and threaded Cleanout Adapter to prevent smoke leakage at the setup area. Proper blower setup is critical for safety - always follow proper smoke test procedures.

Can I test large or multi-story structures with the P2?

Absolutely! Don’t let the compact size of the P2 fool you. The P2 is a great choice for testing building plumbing of structures both big and small. For very large buildings the goal is not necessarily to fill the entire system with smoke at one time - as you likely would not have the manpower to inspect all that plumbing at once anyway. A better solution is to break up the system into sections and relocate the blower as needed. Pipe plugs are another fantastic way to localize tests on a large system.

Do I need to be a professional to use the P2?

The P2 is designed for professional plumbers and contractors. While operation is straightforward, smoke testing procedures and setup can vary by application, and best results are achieved by trained professionals familiar with plumbing diagnostics.

What maintenance does the P2 require?

Routine maintenance is minimal and typically includes basic inspection, proper storage, and occasional cleaning. The unit is designed for durability and repeat jobsite use with minimal upkeep.

Is service and repair available if something goes wrong?

Yes. The P2 is backed by a strong warranty and full U.S.-based service and repair support. In the unlikely event of an issue, repairs, parts, and support are handled directly by the same team that designs and builds Blowfish equipment.

Plumbing smoke testing is a diagnostic method used to identify leaks and defects in building plumbing. By introducing visible smoke into the plumbing system, professionals can quickly observe where smoke escapes—pinpointing cracked pipes, loose fittings, failed seals, and other hidden issues that are difficult to detect with traditional inspection methods.

It is widely used in residential, commercial, and sewer lateral inspections because it provides fast, visual confirmation of system integrity without invasive demolition. When performed with professional equipment and controlled airflow, smoke testing is clean, effective, and highly precise.
