have 2 sizes of guzzlers. They are both 2 feet deep. One
is 4 ft. in diameter and the other is 7 ft. in diameter.
The drinker tray is the same size on both – 7.5’x2’ wedge.
The size of hole that you will need will depend on which
size tank you are installing. The hole for either one will
need to be approximately 20 inches deep. I suggest digging
the hole at least 1 foot larger in diameter than the
diameter of the tank to make backfilling the hole easier.
AS FOR THE HOLE -
"YOU CAN DIG IT WITH A SHOVEL,
YOU CAN DIG IT WITH A RAKE.
BUT ONE THING IS FOR CERTAIN,
CAN'T TELL HOW LONG IT'LL TAKE!"
All Dr. Seuss aside, I do not recommend using a shovel. We
have installed them using a skid loader and a backhoe. The
choice depends on two things – which do you have available
and how hard the ground is. A backhoe will work better in
dry clay soils because you can put more down pressure on it.
You need to get the bottom of the whole level and flat –
free of clods. The skid loader works good in sandy or loamy
soils. The drinker tray is attached to the tank with
flexible hose so it is best to have a deeper hole right
where they attach so there is no pressure on the ell
fittings and the hose is not kinked or crushed. The hole
will look like a key hole when you are finished digging.
Place lid on the ground to mark where to dig. Dig out hole
for tank then dig out sloping hole for the drinking tray.
Point tray to south so sun will shine on it in the winter.
