The uninsulated Jug Earth tubes offer an added layer of protection to prevent the earth from touching your waterline. Featuring a 15" OD, corrugated plastic tubing won't rust, resists rot and holds up to chemically active soil conditions. The tubes are strong! The corrugated design provides rigidity without bulk when back filled with earth.
The Uninsulated Earth Tube features a 15" OD and is manufactured of corrugated plastic tubing. Often used to extend the Insulated Earth Tube into warm ground below the frost line and form the heat well using the Earth Tube Coupler.
Available in 2', 3', 4' sections. Bury your waterline at least 1 foot below your frost line and keep the top of the Earth tube level with the top of the concrete pad.
