Locate the water line at a point near your home's foundation.
Use your shovel to carefully clear an area around the incoming line (at least 6 inches clearance around the pipe when done) to allow complete access to an 8-inch or larger length of exposed pipe.
Clean the pipe using water and sandpaper for a tight fit.
Clamp the magnet (using straps, carriage bolts or epoxy as included with the clamp housing) tightly around the pipe.
Refill the excavation, being careful to pack earth tightly under the pipe, so the water line is not stressed in the future.
Things You Will Need
- Strong permanent magnet in pipe-clamp housing
- Wet-and-dry sandpaper
- If you choose to use an electromagnet rather than a permanent magnet, add a water-resistant sealing compound around the wire connection to the magnet housing and a flexible conduit to protect the electric line.
