Rain Water Leak Testing

Sealtech RV Leak Detector

This new machine draws in a high volume of air from a roof vent and disperses it throughout the coach. With all the doors and windows closed, the coach is pressurized slightly.

 

A soapy water solution is sprayed on the exterior components that penetrate the coach "shell".

Bubbles indicate a leak - where air gets out, water can get in! This roof seam leak caused a lot of interior water damage.

 

 

This door and door frame show extensive leaking.

Another problem at a component hatch.

 

This moulding is leaking.

Window leak problem.

 

More leaks.

The foam rubber seals around the window frames has compressed and deteriorated to the point that every window is leaking on this unit. This has caused extensive delamination of the exterior fiberglass panels and dry rot on the interior.

One reader asks:

"Too cool! Is this really a legitimate test to do and is it practical to expect to be able to plug the leaks? Where can a person get this done? The article (which had great pictures by the way) did not have a date on it so I can't determine how 'new' the machine is now. I'd never heard of such a thing but it makes sense to me and is a whole lot better idea than spraying the mh with water and waiting to see where the leaks show up to do damage!"

Answer:

Yes, this is a legitimate test and it does very well at finding leaks sources. I took all of these pictures myself. The machine and process have been around for at least 8 years, that I know of.

It takes about an hour to do a test. It is very practical as it shows where the exterior source of the leak is located. This may be several feet from where the water eventually shows up in the interior.
