Water Reservoir Model No. ME-8594
Introduction
The Water Reservoir is a plastic, graduated cylinder
used as a water source for equipment such as the ETHydro Accessory (ET-8772) and the ET-Generator (ET-
8771).

The Water Reservoir holds up to 1 liter of water and is
graduated in 10 increments of 100 mL and 90
increments of 10 mL. On the unmarked side of the
reservoir are three ports with three hose fittings. The
hose fittings are glued to the cylinder and are not
removable. The top fitting is for attaching the hose that
connects to an external water supply. The middle
fitting is for attaching the overflow hose, which
prevents water from overflowing the cylinder. Water
exits the cylinder through the bottom hose fitting.
Two plastic clamps are included with the reservoir to
control water flow. The Water Reservoir can be used in
two ways: 1) to supply a preset volume of water and 2)
to supply water continuously at a constant head, or pressure.
Equipment Setup
1. Cut the plastic tubing into pieces of tubing long
enough for your experiment or application. (Note: To
avoid cutting the tubing too short or too long, we
recommend that you set up and measure the tubing
length needed before cutting the tubing.)

2. Fit one piece of tubing over each of the three hose
fittings (Figure 1).
3. Attach one (or two) clamps to the bottom piece of
tubing. Tightly close the clamp to the bottom tube.
(CAUTION: If the clamp is not closed tight, water
will drain out of the bottom tube. To prevent
drainage, slip the tube through the indented portion of
the clamp, and snap the clamp completely shut.)
Note: The fittings on the Water Reservoir are oversized
to reduce friction and maximize water flow. If you have
difficulty inserting the tubing to the fitting, apply a small
amount of glycerine to the tubing.
