CAUTION: For trouble-free pump priming (up to 4 feet above the water line), first install a 6” long riser in the discharge
connection on top of the pump. Then install an elbow and lead the discharge line downward to the discharge connection at
the BaduJet Imperial jet housing.
CAUTION: Allow at least 12 hours curing and bonding time. Insufficient curing and bonding time can result in leaks and
flooding.
CAUTION: Throughout the entire installation, make sure the plumbing connected to the BaduJet Imperial jet housing is well
supported. Unsupported plumbing WILL crack the jet housing.
CAUTION: DO NOT use the pump as a fixed point (support) for the plumbing.
CAUTION: When using 6” pipe, install 6” x 4” reducer bushings at the jet housing suction and discharge connections.
The 6” suction line should be run from the jet housing and remain under the water line to a point directly beneath the pump.
Install a 6” elbow at that point. Then run 4” pipe vertically up to the suction connection of the pump and finish with a 4”
elbow.
CAUTION: The BaduJet Imperial system includes 30 ft of cable for the LED light and two 30 ft lengths of air tubing for the air
buttons. If the control box cannot be located within 30 ft of the jet housing, please contact the factory at (800) 223-8538
or technical.usa@speck-pumps.com.
NOTE: Suction lines which are too long have significant disadvantages:
Plumbing Installation - Continued
For optimal performance, use 4” plumbing when the
total distance between the pump and jet housing is
30 ft or less. The plumbing should be as direct and
free from turns or bends as possible because elbows
and other fittings can create large friction losses
and reduce the performance of the system.
The shortest length of pipe with the minimum
number of fittings possible should be used to
avoid any significant friction loss due to the pipe
and fittings. NOTE: Refer to Figure 2 for the BaduJet
Imperial head loss curve.
A maximum of seven (7) 90
o
4” elbows may be used
with 30 ft of horizontal 4” pipe for the suction line
and 30 ft of horizontal 4” pipe for the discharge line
without negatively affecting the performance of the
system.

Higher resistance which results in less efficient priming and a higher risk of cavitation.
Longer priming time (up to 12 min).
Keep the suction and discharge lines as short and straight as possible.
If the pump is positioned further away, then the pipe dimensioning has to be adapted so that almost loss-free flowing
is ensured.

If more elbows are required for the installation, 4” sweeps must be used in place of the elbows. When using sweeps
instead of elbows, a maximum of nine (9) 4” sweeps may be used with 30 ft of horizontal 4” pipe for the suction line
and 30 ft of horizontal 4” pipe for the discharge line without negatively affecting the performance of the system.
If the pump cannot be located within 30 ft of the jet housing with the maximum number of 4” elbows or sweeps stated
above, then 6” plumbing must be used. For the suction line, use 6” plumbing and fittings from the connection at the jet
housing to a point directly beneath the pump. From that point, install a 6” elbow. Then run 4” pipe vertically up to the
suction connection of the pump and finish with a 4” elbow. For the discharge line, 6” plumbing should be installed from
the discharge connection of the pump all the way to the discharge connection of the jet housing.
