Jug Insulated Earth Tube - Variety of Lengths

The JUG Insulated Earth Tubes provide superior protection for your waterline by insulating it below the frost line. With a 15-inch outer diameter and 10-inch inner diameter, these corrugated plastic tubes are lined with 5 inches of foam insulation, ensuring energy efficiency and minimizing heat loss into the frozen ground. The durable poly exterior resists rust, rot, and chemically active soil, while the corrugated design adds rigidity to withstand ground movement caused by freezing and thawing.

Available in 2', 3', and 4' sections, these Earth Tubes are easy to install and can be extended using an Earth Tube Coupler (sold separately). Bury the waterline at least 1 foot below your frost line and ensure the tube's top is level with the concrete pad for optimal performance. The Earth Tube is designed to insulate waterlines below ground and does not feature a tapered design.
