We had a problem the first year here from a combination of leaves blocking the sewer right past our house and tree roots in the lines. After the pumping and clean-up got a check-valve put in the sewer line right away.
We still have to have the pipes drilled once a year because of the damn tree roots, but at least the problem now tends to be of the order "things drain veerrrry slooowwwly" or "the shower backed up into the basement" rather than "the sewer decided to flow into house instead of down the street".
