INSTALLATION PROCEDURES
MULTIPLE TANK INSTALLATION PROCEDURE
Typical Submersible Pump Installation
FIGURE 1.
1. When replacing an existing water tank, drain-off water and
bleed-off air completely from tank before discarding.
2. Set and position new tank on a firm, level surface with adequate
drainage. Typical installation shown in figures 1 & 2.
3. For best results use new piping; i.e.: Iron, copper, or rigid PVC.
4. If your system is capable of exceeding a working pressure of
125/100 psig (typically submersible pumps), install a pressure
relief valve (rated at 125/100 psig or less, but greater than
turn off pressure) in the system no more than 10 feet from the
tank. The valve should be the same pipe size as the tank outlet.
This is not necessary on tank-mounted jet pump units.
Typical Jet Pump Installation

5. Connect tank to the pump discharge line using the same
size pipe as the pump tap, or larger.
6. The tank should be flushed 5 times prior to household
use, see Operation section.
Water system tanks can be connected together to increase supply
of usable water (drawdown). Two tanks of same size will double
the supply and three tanks will triple the supply. When using a high
capacity pump, the manifold and pressure switch assembly must
be installed in the pipe line as close to center of tanks as possible.
Manifold and main should be 2 times the size of feederline.
