Query: A MUST for septic systems!

After moving from the city & having a life of a city water supply, & no worries using the garbage disposal, I move to the woods...now I have a septic system. I had MANY mishaps the first few years...& after numerous & quite expensive "dates" with my plumber, I heard about Rid-X. I started using it, & felt very comfortable that my system was happy...only one problem,I'd forget to buy it every now & then, or the store didn't carry it, & I wasn't as reverent with the process as I should have been.Then Amazon.com came to my rescue. I now have a monthly delivery right to my door & the day it is delivered is the day it's putto use. Now, I never miss a month, I don't worry as much about my septic system, & I've been able to lose the plumber!
