Animals Easily Adapt to the JUG Waterer

With the JUG, animals can see and smell clean, fresh water. They do not have to learn to lift flaps or push balls and floats out of the way to get a drink. An internal, pilot-operated float valve which is adjustable from the outside of the JUG, automatically keeps the water at the determined level.

Thermal energy, Not electric energy

The “Draw Tube” is really three tubes. Two copper and one CPVC. As the water gets cold in the drinking bowl, it becomes heavier and sinks down the CPVC tube forcing the warm tank water up the copper tubes into the drinking bowl. This keeps the water in the bowl from freezing by slowly circulating it and replenishing it with warmer water from the bottom of the reservoir.

In addition, the copper tubes are designed with a large surface area in the Feed Trap. Since copper is an excellent heat conductor, heat is transferred from the tank water to the trap area through the copper tube walls.

For Energy Free Models in marginal climates, you need enough animals drinking to keep water in the tank warm enough to provide heat energy (At least 15 head per drinking bowl.) Otherwise a small 65-watt heater may be added to make the JUG Energy Efficient. In either case it is primarily thermal energy, not electrical energy keeping the water fresh and at a constant temperature, summer and winter. The average electrical cost for a JUG Livestock Waterer is $10.00 for the Entire Sea-son.

The Jug is super insulated with urethane foam to conserve heat loss, and is very reliable in extreme cold and wind chills.

It’s like a Thermos JUG.


Features of the JUG

External Adjustment Screw JUG

JUG Livestock Waterers have an external adjustment screw. Simply turn the screw with a coin or screwdriver. It is not necessary to remove the lid to raise the water level in the drinking bowl. When the animals know the JUG is their drinking station, return the water to its lower operating level to minimize the amount of water exposed to the weather.

Inspection Cover

The JUG has an inspection cover that can be easily removed for inspection and service to the float valve.

External Drain Plug

The External Drain Plug allows easy draining of the water from the JUG tank. The JUG’s design keeps the water free from feed or hay, but most water has iron bacteria which will leave a residue in the tank over time. It is therefore wise to drain the tank periodically.

New JUG Installations

install-option-1 install-option-2

OPTION #1 Water Supplied by Heavy Duty Shut Off & Drain

This shows the use of the water supply Heavy Duty Shut Off & Drain. Advantage: If the JUG is installed in a location where animals will not be using it for long periods of time, the water can be shut-off and the water in the riser will be drained away. The JUG tank should also be drained and the incoming electric supply disconnected if it is an energy-efficient model.

For this installation you will need:

    1. Energy-Free or Energy-Efficient JUG
    2. Insulated Earth Tube
    3. Uninsulated Earth Tube
    4. Coupler for Earth Tubes
    5. Heavy Duty Shut Off & Drain
    6. Mounting Bracket for HD Shut Off & Drain
    7. Anchor Bolt Kit

OPTION #2 Water Line / Ball Shut Off Combination

In this option the user furnishes the incoming water supply to the Shut Off Ball Valve.

For this installation you will need:

  1. Energy-Free or Energy-Efficient JUG
  2. Insulated Earth Tube
  3. Uninsulated Earth Tube
  4. Coupler for Earth Tubes
  5. Top Mounting Bracket
  6. Shut Off Ball Valve
  7. Anchor Bolt Kit

JUG Mounting Pad Information


Replacing an Existing Waterer

The Energy Efficient JUG is the choice when replacing a worn-out old fountain. This requires no excavation; just bolt the JUG down to your existing mounting pad. The JUG Waterer has a low wattage (65 watt) heating element and thermostat to provide “insurance” in cold climates. If your existing incoming water line is in an open uninsulated tile and you have been experiencing waterline freeze ups in the past, it is a good idea to install a low wattage (42 Watt) 5 Foot Air Space Heater in the tile when you install your new JUG. For warm climate areas the Energy Free JUG is the model of choice.
