: Deb,

: Thanks for your reply. When you say a clogged drainage line, do you mean in the house or from the house to the septic tanks? Is this something a little Drano or Liquid Plumr can fix or is it bigger than that?

: Again, thanks.

Do NOT use chemical drain cleaners like Drano or Liquid Plumber EVER (not yelling, just raising my voice a little :-). Most of us plumbers think those products should be illegal--they do not work, and can cause damage to people and equipment.
If you have an outside cleanout, you can open it and determine if the drainage water is flowing by this point. If not, the clog is inside the house. If so, the clog is between the cleanout and the septic tank. The inlet baffle is a favorite place for stuff to clog.
