This well tank has been designed to store and deliver
water under pressure between pump cycles in a domestic
water system. It features a patented Controlled Action
Diaphragm (CAD2) system that completely contains the
system water in a safe SF approved chamber. The CAD2
system prevents water from ever touching the internal
walls of the tank which greatly reduces external conden-
sation. Each tank is finished with a two coat appliance
quality paint finish to minimize external corrosion.
  
Without a storage tank, a domestic water system’s pump
would cycle (turn on) every time there was a demand for
water. This frequent and potentially short cycling would
shorten the useful life of the pump. Flexcon well tanks are
designed to store water when the pump is running and
then deliver pressurized water back to the system when the
pump is shut off. A properly sized well tank will store at least
one gallon of water for every gallon per minute (GPM) of
pump capacity. This allows for fewer pump starts and longer
run times which should maximize the life of the pump.

Select a location where a water leak will not cause prop-
erty damage and provides adequate means for water
drainage. This well tank and the associated piping may in
time leak. The manufacturer is not responsible for any
water damage that may occur in association with the well
tank installation. The tank location should be as close as
possible to the system pressure switch to reduce the
negative effects of friction/elevation pressure loss. This
tank has been designed to be mounted on a level surface
and must be adequately supported around the entire base.

Before turning on the water supply to the system, open a
water faucet to allow air from the system piping to be
released. Turn on the power to the water supply and the
pump should turn on, filling the system piping. When the

faucet. The pump will continue to run filling the well tank.
Inspect the installation for water leaks paying close
