Installation of 303 Riser Tubes
The Water Supply Line servicing the 303 JUG Waterer must be buried at a sufficient depth below the frost
line to prevent it from freezing. The size waterline of choice going from the buried horizontal underground
waterline up through the Riser Tube into the 303 JUG is 1/2” inch in diameter. This is a commonly used
size, and will allow enough room for the waterline to get from the riser tube up into the Service Tunnel of
the JUG. Initially extend the incoming water line about 6 inches above the top of the 303 riser tube (for
good measure). Then, when ready for final placement of the 303 on the riser tube, cut the line down to
about 2 inches above the top of the riser tube. For With Heat JUG Waterers, run the Electrical Line under-
ground along with the Water Line, leaving the proper distance between the two lines, as recommended by
your electrician and plumber. Contact your electrician for the proper sizing of electric line to be used to
accommodate the 30 Watt 120 Volt Heater in a With Heat JUG, as well as the string heater that is placed
down the 303 riser tube.

Installation of the 303 JUG Horse Stall Waterer
when not using 303 Riser Tubes.
When a 303 is not mounted on top of a 303 Riser Tube it will be necessary to “Field Drill” the hole in
the JUG that will accommodate the incoming waterline. The proper size hole (the size of your
incoming water line) can be drilled in the back area of the JUG. This is the area that is not part of
the water reservoir. The water line can enter the JUG through the top or the bottom. The size of the
incoming water line will then need to be adapted to the 1/2 inch 303 shut off valve that is mounted
inside the Service Tunnel of the 303.
Mounting the 303 JUG to the wall
If mounting on top of a 303 Riser Tube, slide the JUG on top of the tube. The Riser Tube will extend
up into the JUG approximately 1 1/2 inches.
Mounting Holes Used
Top———Use all 4 Holes
Bottom—–Use 2 Front Holes
Flushing The Water Line
Remove the Front Half Float Valve by turning it counter
clockwise 1/4 turn and pulling it out of the Float Valve Base,
as shown on the following page. Turn on the incoming
water supply and let it run freely for a few minutes. The
water reservoir will need to be drained away at this time by
removing the External Drain Plug. Turn the water off and
reinstall the Front Half Float Valve and the External Drain
Plug. Turn the water back on.
Final Installation Steps
After connecting the power to the Heater and Thermostat, (see wiring diagram on following pages).
Install the 303 JUG Lid.
***Be careful not to cross thread the bolts as they are turned into the brass inserts.***
Turn the water on and fill the reservoir to the desired level. You can adjust this by turning the
External Adjustment Shaft. Ideally the water level out in the drinking bowl will be 1/2 inch above the
highest part (back side) of the drinking hole.
Installation of the 303 JUG Horse Stall Waterer
when using 303 Riser Tubes
Insert the 1/2 inch X 1/2 inch Hose Barb/Elbow into the incoming 1/2 inch waterline and secure with
a hose clamp. (If you are not using a standard 1/2 inch waterline to supply the 303 Jug, you will
need to provide your own Barb/Elbow fitting components.) Using thread sealant, attach the
enclosed Brass Nipple to the incoming Barb/Elbow. Attach the 1/2 inch end of the enclosed 303
flex hose to the incoming Brass Nipple and tighten securely. Gently ease the Flex Hose up into the
Service Tunnel of the 303 as you slide the fountain on the riser tube. Attach the small fitting on the
other end of the 303 Flex Hose to the threaded Brass Elbow coming out of the end of the 303 Shut
Off Valve, and tighten securely. When the water line has been properly flushed and checked for
leaks, and the electricity (if with heat) has been properly hooked up, and the 303 has been
mounted to the wall, pump sealant between the outside of the riser tube and the 4 inch hole on the
bottom of the 303 to create a good weather seal.
Corner Mount 303: Mount the
JUG to the wall using the 303 Wall
Mounting Kit.
Flat Back 303: “Field Drill” 6 holes in the back wall of the Flat Back 303.
The holes should be drilled in such places so that when lag bolts with
washers are placed through them that they will attach to the strongest
points of the wall available. Use whatever length of Lag Bolts fit your
specific mounting situation.

Diaphragm
Trouble Shooting Tip
If at sometime you find the bowls over flowing:
Clean and, or replace the diaphragm, as this will almost always be the cause of a JUG over
flowing. It is recommended that the diaphragm be replaced every year.
Check all connections and fittings for leaks.
If the Float Valve is working properly but you are having trouble getting enough water in the
Drinking Bowl check to see that the Plumbing (hoses, etc.) inside the Service Tunnel are not
“pulling” the Float Valve down so that it can’t be raised high enough by turning the External Float
Adjustment. In this case “twist, turn or pull” the plumbing so it is in a position of pushing up on
the Float Valve instead of pulling it down.

JUG Fluidmaster Valve Flow Rates
The Fluidmaster Float Valve used on the 303 is among the most reliable , trouble free valves
available today. Because of the precision qualities built into the valve, it is to your benefit to see
that at the time of installation your water supply is clean. Please follow these guidelines to en-
sure proper installation.
1. Flush sufficient water through the water line before attaching the Float Valve.
2. Attach the Float Valve to the Water Line.
3. Turn on the water supply.
4. Let the reservoir fill a few times.
5. Turn off the water supply.
6. Remove the Front Half Float Valve. This is done by giving the tabs at the base of the gray
arm a 1/4 turn counter clockwise and removing it from the base of the valve.
7. Remove the rubber Diaphragm from the stainless pin and wash all components. Reinstall the
Diaphragm on the stainless pin.
8. Reinstall the Front Half Float Valve by placing it back into the Float Valve Base, and turning it
1/4 turn clockwise.
9. Turn on the water supply.
10. We recommend that you do this procedure a few times. If you still realize dripping water you
need to do it again.
11. At this time check all water fittings , and connections for leaks.
By following these instructions you should realize the trouble free performance of the 303 JUG
that customers have come to expect over the years.

When placing a 303 JUG on a 303 Riser
Tube, it is recommended that a string
heater be placed down the riser tube and
tied into the electric line. The length of the
heater is determined by the depth of the
riser tube. Select the longest heater possi-
ble without letting it lay in the dirt at the
bottom of the hole.

Feed Trap Maintenance
Because of it’s “Draw Tube” design, the JUG Livestock Waterer will provide the cleanest water
available to your animals. The JUG Feed Trap (where the Draw Tubes attach to the bottom of the
lid) will catch most of the feed that falls off the animals face. Because of the suction action created
in the feed trap while drinking, most animals will “self clean” the JUG. However, over a period of
time, feed will accumulate in the feed trap. A proven and quick method of removing that feed from
the feed trap is with a wet/dry vac. A vacuum as small as 2 gallons will work well. One or two sucks
with the vacuum will do an excellent job of cleaning the feed trap.
Remember that draining the 2 gallon reservoir of the
303 JUG is as easy as removing the front mounted
external drain plug.
