My leak test setup
I've been lurking for a while and decided to post a couple of pics of my leak test setup. I bought my first TT a month or so ago and she has a leak and some water damage to the floor (working on fixi...

Several years back I ran a DIY leak test using an electric leaf blower. I did find some leaks but always wondered whether I was getting enough air pressure inside. I had used my U-tube manometer to measure the pressure and got about 0.7 inches of water. (In the picture the red stuff is colored water and each line is 1/2 inch)
A couple of weeks ago someone here posted a link to the Sealtech company, the folks that make the equipment for the "official" leak test done by RV dealers. This page on the Sealtech website has a link to their operating instructions, which says that the normal pressure should be between 0.3 and 0.6 inches of water. So any blower system that can produce that range of pressure will duplicate the Sealtech test.
When the weather warms up I'm going to hook up my manometer and see if I can get sufficient pressure by running the MH cab air blower on high and running my TurboMaxx fan on the bathroom vent full speed blowing in. Perhaps I don't really need the leaf blower.
let us know what you find for pressure. I have two fantastic fan vents, I'm curious to see if having them "suck" rather than "blow" might give enough pressure. IMHO you don't want much pressure, you don't want to make leaks, and soapy water doesn't take much to make a bubble.
I'll probably give my two fans a try. As far as I know I don't have any leaks but who knows!
