I had my septic tank pumped yesterday, first time since we built the house 4 years ago. The gent who pumped it thought there was a large amount of paper in the tank, which may be true with 3 small children in the home...they sometimes will fill the bowl with t.p. then Daddy needs to 'remind' them. Anyway, while I had the lid off, he suggested I put a garden hose in the line that runs out the side of the tank to the distribution box. As luck would have it, it appears that there must be a clog somewhere from the tank to the distribution box or worse yet in the leach field /forums/images/graemlins/crazy.gif b/c it was running s-l-o-w. I am going to need to get to the distribution box and see if the clog is within there. Is it common to find a clog within the box? Can any of you off a tip or two about my dilemma?
