Leak testing tubes
 
What is the best method used for identifying leaks in sponsons? Is there one where there is a UV dye added to the pumped air?
I don't want to do it myself........just intrigued, as it may need to be farmed out soon.

Haven't heard of using a dye, but might be a great idea, after all other industries use it for leak detection.

Generally for liquid leak detection. Don't know of any gas leak detection that uses a dye. Then again, I don't know that much about gas leak detection, anyway.

If you use a really soapy mix and spend ages being really thourough tiny bubbles will be there.

Boat sat outside in the rain on a calm dayworks wonders.

I have been chasing a tiny leak in my forward toob for over a year. Found it just before I launched on the shores of loch lomond last month as the rain soaked everything and a little bubbly wet hiss was heard. Also found two others in a similar way after having painted the toobs about three dozen times with the soapy water looking for them.

You mean you can't find it.

Refrigerant gases can have UV dyes added for leak detection.

Another interesting concept is http://www.cs-instruments.com/int/do.../page40-41.pdf It basically listens for the leak. This particular model will probably not work at the relatively low pressures we use but maybe there is something there.

There is probably a good reason the tube guys I know use soapy water.

The acoustic leak detectors need a leak of 6 bar.
Snoop is what we use for finding leaks and if we run out of that its soapy water.
