Roof Vent Early Warning System - Save 1000's of $$$$
Here is a tip for you.  Leaky sewer vents are so destructive, so deceptive, so sneaky, that I have decided to install an "early warning" system on two of my 3 vent pipes, the two that I can get access to. Both of these vents go into my holding tanks that sit in a pan that I just had to re-build because it was rusted out. Those of you who have "been there, done that" know what I'm talking about. I never want to have a "leaky" sewer vent, ever again! Now, this is a high-tech solution, so follow this very carefully. I am going to tie an old white cotton sock around each vent pipe, up about head height, just below where they come through the roof. The two vent pipes that I can get to are both hidden in closets, so the socks will not be noticable. Then periodically, after it rains, I will feel the socks to see if there is any evidence of moisture!! If I got moisture, then I have a LEAK! SHAZAM! Simple and effective! The price is right, too! Airstream should offer these as a required accessory. 
Cheers, Bill
P.S. - I have been haveing all kinds of trouble posting to and reading the Forums. Something is definitely WRONG!!

My socks are the larger size 10- 15, will they work too? Do you recommend dress socks or athletic style? I am thinking Athletic.
I wonder if they do take on water will the extra weight cause any problems?
Thank you for your help, If I can verify the correct style of sock I am going to install a set asap!

Sock selection
Well, let's see. After thinking on it some more, I believe the socks should definitely be used, but clean, and made of COTTON. The Cotton will absorb and hold water effectively. The color is your choice, but I like white. A well used athletic style is ideal, the bigger sizes might have to be cut down in size a bit to go around the vent pipe if the space is tight. So there you have it!
Somewhere, I have seen some kind of material that is initially PINK and then it turns BLUE when it gets wet. Hmmm......  now that has definite possibilities. Bill

I have quite large supply of used white athletic socks that I had been thinking of throwing away. Now, I'm thinking that I might be able to sell them on Ebay.
If I list them as "RV leaky sewer vent early warning system" would you want a share of each pair that I sell? Or, would selling them on Ebay be cutting into your market?

It wouldn't be too difficult to place two wire loops close together in the material of choice as electrodes to get an indicator similar to the tank monitors we know and love - a 10-year lithium 9 volt battery, a couple of FET transistors, etc., and a LED and you have a high tech moisture intrusion signal...
