No, I'm not being unpatriotic.
A septic system expert once recommended to me to use the 4th of July and Thanksgiving as reminder days for switching between leech lines in my septic field. There are two lines and switching approx. every six months gives the soil around them an opportunity to dry out and 'rest' to maintain efficiency.
Don't know how accurate that advice is but I do the switch and have never had a problem in eight years or the six years prior to our buying the house. So, I'm not about to stop the practice to find out if it works or not.
