Plumbing cost estimates

[Philip Unger]

What is an average cost for a pipe repair under a house? The plumbing in this house is copper and galvanized mixed, but mostly galvanized. The house was built in the late 1920's. The galvanized pipes, for the most part, are decent, except where they run down into the ground. The galvanized pipe has to be replaced due to a rust spot that broke through. Also, a tee also has to be replaced.
