Testing drains and pipes using smoke machines

Our specialist fog machine kit specifically designed for testing the integrity of drains. It generates a persistent water-based non-toxic smoke and is very easy to use.

It may just transform the way you test drains!

Concept Portable Drain / Pipe Testing Smoke Generator

Photo above: The DrainTester in off-power operation.
The green drain bag shown inflated above would slide into the opening of the pipe you are testing whilst deflated, and then be inflated inside the pipe to create a seal.
The thick black tube ducts the smoke through the inflatable bag and into the pipe, and the smaller black pipe is used to inflate the bag and has standard fittings to connect to an air pump.

A user friendly, effective and non toxic means of introducing smoke into drains - the DRAINTESTER is the ultimate tool.

• Clean, simple and cost effective, with a 5 year parts warranty
• Produces smoke on demand - simple push button operation
• Can be user “off power” once pre-heated
• Uses re-sealable aerosols to produce up to 15 minutes of
smoke per canister

• Can travel through hundreds of metres of drains
• Dense, highly visible, with a distinct odour
• Is water based, non toxic and completely controllable

• Drastically reduced running costs
• User friendly, easy operation
• Greatly enhanced performance and safety compared to existing pyrotechnic smoke methods

Perfect for pest controllers

(please specify when ordering)

The DrainTester allows you to operate the unit off-mains power - you can produce a considerable amount of smoke using the retained energy within the high mass heat exchanger, allowing you to carry the generator around, making smoke as required, without a trailing electrical lead. After being on mains for around 15 minutes, the DrainTester will generate large amounts of smoke for around 2 minutes whilst off power. Connected to the mains, the DrainTester can operate continuously at full output.

An open-air example of how the drain bag would be inflated inside the open end of the pipe to seal it and the smoke does not exit.

Operation off the mains power supply? Yes

The DrainTester's basic principle of operation is simple. Use the DrainTester to fill the pipework with smoke. The pipe system should ideally have an open end. When smoke starts to exit the open end, this signals the pipework is filled with smoke and you simply need to cap it off. Leaks in the pipes will be shown by smoke exiting from them. The DrainTester does not produce pressurised smoke, but is normally sufficient to visualise any leaks.
