FYI..................................

I put a lot of effort into controlling air leaks and have owned my Newell for over 8 years.  I would find an air pump cycling every 20 minutes totally unacceptable.  My 12V air pump cycles once a day and my 120V air pump cycles 3 or 4 times a day when the coach is not in use. 

95% of my air leaks have been found without going under the coach!  When I start looking for air leaks, I start in the first compartment on the right side and work my way around the coach.  Then I go inside the coach.  Lastly I go under the coach.  All but one air leak I have found has been at either a component or connection.  The key to finding leaks is being organized and understanding how to isolate components and connections to determine where you do and don't have a leak.  Also having the right tools and understanding what they are good for and what they don't do is also important.  C this thread:  http://newellgurus.com/showthread.php?tid=2705

Remember 20 very small leaks can look like one big leak.  I have never found the "shotgun method" an effective use of time.

Good luck in your search................................
