You're welcome. I DIY pressure test using a 120V furnace squirrel cage mounted in a window. The furnace blower gives me a pressure of 1" differential displacement, perfect for pressure testing. A homemade manometer made from a vinyl tube and secured to a board can be used for accuracy of pressure.Other folks use a leaf blower or floor dryer and report success. Any kind of air mover that delivers a fairly good amount of air into the cabin will work. It is about volume and not about pressure.
Typically, I use five sheets of paper depicting the four walls and the roof, marking off where bubbles appear when pressurized. A user can draw in windows, doors, awning hardware, vents, and such to get an accurate depiction of leak locations.
