PLUMBING

EccoFlo recommends at least 1 ft (.3m) of 1/2" (13mm) I.D. flexible high pressure tubing to
both ports. Ideally the pump's ports/strainer should not be connected to plastic or rigid
pipe. The pump's normal oscillation may transmit through rigid plumbing causing noise, and
possibly loosen or crack components.
Installation of the 50-mesh strainer such as is recommended to prevent foreign debris from
entering the pump. EccoFlo hex/swivel barb fittings provide easy removal if maintenance
or access is required. The fittings are designed with a "taper-seal", creating a water tight
connection when hand-tightened. Always secure barb tubing connections with properly sized
stainless steel clamps to prevent leaks. Never use plumbers tape or sealing compounds on
threads. Sealer may enter the pumps causing a failure. Failure due to foreign debris is not
covered under warranty.
Rapid cycling may be caused by excessive back pressure created by one or more of the
following within a plumbing system: Water filters and purifiers not on separate feed lines,
flow restrictors in faucets and shower heads, small ID lines pipe/tubing should be at least
1/2" (13mm) for main lines, restrictive fittings and connections (elbows, "T"s, feeder lines to
faucets, etc.) The pump with by-pass do not need to use pressure tank. If the pump is cycling
rapidly increase the setting by turning the screw clockwise (1 ½ turn max) until the pump
operates for 1 sec. with at least 2 sec." OFF time".
The pump's duty cycle is: intermittently. Do not use the pump under anti-osmosis filtering
systems. Continuous running under higher pressure may reduce pump life and it is not under
the warranty.

OPERATION

(This pump is designed for intermittent duty only.)
The pump operates normally up to about 40-psi, where a spring-loaded by-pass valve opens,
allowing flow back from the output side to the input side, providing smooth, steady flow with
virtually no cycling, all the way down to a trickle. As a faucet is opened back up, the pressure
will drop, the by-pass will close and full flow is again obtained. This allows good flow, even
with today's restrictive showers and pullout sprayer faucets. Performance will vary, of course,
depending on the voltage to the pump; lower voltage = lower flow, higher voltage = higher
flow. Remember your electrical safety: It is always best to shut off power to the pump OFF
when leaving the RV unattended.
About the by-pass NOTE: By-pass adjustment should be performed by professional
technicians with proper gauge and equipment.
The by-pass is a spring loaded diaphragm that opens up allowing water from the discharge
side back to the inlet side. The by-pass is set to begin opening at about 40psi and increasing
full by-pass at about 62 psi. The pressure switch on the pump is set to shut off at 55 psi. If the
switch or by-pass is adjusted too much, the by-pass and switch shut-off pressure. Unscrewing
the switch screw counterclockwise will lower the pump shut-off pressure. Screwing the by-pass
screw in will raise the pressure at which the by-pass starts and lower the full by-pass pressure.
