Jarl is a pillar of the community who always does the job right. He can sleep peacefully at night, knowing that his work will hold water. It is useful to compare how each handle various residential plumbing challenges. The homeowner responsibility for the water supply system begins at a junction to the city utility equipment. This is typically just inside the property line and about two feet underground.
Many older houses have a steel water supply pipe which is steadily corroding.
When this finally springs a leak, Joe Camel will go into action with his shovel to find the hole, patch it, and call it good. Jarl might apply a temporary patch if the pipe is not buried too deep. He will also begin the installation of a new, heavy wall copper pipe. This is placed in a ditch that has no large or sharp rocks, and is inspected by the Water Department before being covered. Jarl will assure freeze protection by covering the pipe with at least two feet of soil, and keeping it at least two feet away from any concrete or rock retaining wall.
