How do I
change the voltage on my jet pump?
Follow the instructions on the motor nameplate, in the
Jet Instruction Manual, or under Terminal Board and
Voltage Change Plug in the Technical Manual.
How do I
prime my pump?
Priming means filling the pump and suction pipe with
water. You must evacuate the air from all the suction
lines and the pump. It may take several minutes to prime
depending on depth to water, pipe size and length. Note:
it is easier to prime a pump if you allow all the air to
escape from the pump and pipes. The water cannot go in
unless the air can escape.
I have a 1/2
hp jet pump manufactured by a Goulds competitor. Will a
1/2 hp Goulds jet pump give me the same flow?
It depends. Pumps should always be sized based on the
application (head and flow), not the horsepower of the
old pump. While many 1/2 hp jet pumps have very similar
performance, it should be known that pumps are available
in high flow or high pressure models with very different
My pump will
not hold prime, why?
Pumps do not hold prime, the piping system does that
job. Jet pumps must be primed on the original start-up.
They will reprime after that as long as the footvalve or
check valve holds and there is no air leak on the
suction side of the pump. See "Priming" in the Jet
What is the
recommended cycle time to extend pump life in a home
The pump should have a minimum cycle time of at least
Will a 1/2 hp
competitor submersible pump give me the same flow as a
Goulds 1/2 hp submersible pump?
Our 1/2 hp submersible pumps are available in four (4)
models. They are designed to flow 5, 7, 10 or 13 gpm.
Make sure that you are comparing not only horsepower,
but also the flow and head produced by the pump. Your
Goulds Professional Pumps Dealer can explain this in
performance improve if I install a larger motor on my
submersible or jet pump? For example, a 10GS05 with 3/4
Absolutely not. GPM and head are based on speed and
impeller diameter. Using a larger horsepower motor does
not affect speed and therefore will not change
How do I buy
a Goulds Pump?

Yellow pages under "pumps".
I have a pump
motor that says "Gould" on it. Did Goulds Pumps
manufacture this motor?
No. Goulds Pumps does not manufacture motors. If you
have a motor that says "Gould" on it, it is probably
made by Gould - Magnetek, a separate company not
affiliated with Goulds Pumps. Anything manufactured by
Goulds Pumps will have the GP logo on it or will have
Goulds Pumps printed across it.
Pumps Hydro Pro Water System Tank has a leak. Can this
No. If a leak occurs in the tank or diaphragm of the
tank, the tank will need to be replaced. If this leak
occurred within 5 years, return the tank for warranty
my bladder tank pressure setting (psi) be?
On a jet or submersible pumping system, the pressure in
the tank should be set at 2 psi below system cut-in
pressure. For a "Balanced Flow System", the pressure in
the tank should be set at 10 psi below the system
package is very common from other manufacturers. Do you
offer any packages?
Goulds Pumps offers a standard package for the
residential grinder, as well as custom packages upon
Are there any
rules for sizing receiver basins?
In some areas, local codes may dictate the size of the
receiver basin. If not, the most important guideline is
to make sure the basin is big enough to do the job.
Select a receiver basin with a total volume of 2½ to 3
times the pump capacity. If possible, specify a tall
basin rather than a wide basin. If the basin is too
wide, solids may settle out on the bottom and cause
Does it void
the warranty to cut the plug from the cord?
No. It has no effect on warranty or agency listings such
as U.L. or C.S.A.
offers a full line of panels for sewage pumps, but do
they offer anyting not already listed?
We quote special panels directly from the vendor daily,
and we welcome any special requests.
pumps be sized in a duplex system?
A duplex system divides the pumping load between the two
pumps and provides backup in case of failure. For this
reason, each pump and discharge pipe should be sized to
handle the maximum anticipated flow.
The pump is
powered and running with no liquid being delivered. What
could be the problem?
The pump is probably airbound. Drill a 3/16" hole 2"
above the pump in the discharge line to allow the air to
What is the
recommended pump down level for a sewage pump?
Goulds Pumps recommends that the motor must remain
covered in water during pumping. We realize this may be
difficult when using small basins for confined spaces.
Our recommendation is for optimal pump life.
What is the
recommended size of piping on the discharge of a pump?
Discharge piping should be at least as large as the
discharge of the pump.
