Plumbing Installation
8
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 BaduStream head loss curve.
A maximum of seven (7) 90
o
elbows may be used with 30 ft of horizontal 4” pipe for the suction line and 30 ft of
horizontal pipe for the discharge line without negatively affecting the performance of the system.
NOTE: This applies to each individual pump used on the system. Refer to Figure 4 for the maximum TDH allowed to
achieve recommended flow rates.
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. NOTE:
This applies to each individual pump used on the system. Refer to Figure 4 for the maximum TDH allowed to achieve
recommended flow rates.
If the pump(s) cannot be located within 30 ft of the jet housing(s) using 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 (or at the manifolds for two and three jet systems) 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
pressure connection of the jet housing (or manifolds for two and three jet systems).
For two and three jet systems, the jet housings must be installed as close to 10” center to center as possible for
maximum performance. DO NOT install the jet housing more than 12” apart on center. (See Figure 1 & 1A)

CAUTION: The discharge connection is at the center of the back of the jet housing. The suction connection is at the bottom
of the jet housing.
CAUTION: The suction line should remain below water level from the suction connection at the jet housing to a point directly
beneath the pump.
CAUTION: The center of the BaduStream jet nozzle(s) must be located 12” BELOW the water line for maximum performance
and efficiency. The air regulator(s) should be located 3-4” ABOVE the water line.
CAUTION: In areas with soft soil conditions or with frequent earth movement, a flexible section of 4” hose should be
installed at the back of the jet housing to prevent plumbing or jet housing damage.
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(s). Then install an elbow and lead the discharge line(s) downward to the discharge connection(s)
at the BaduStream jet housing(s) (Not required with 3.5 HP pump Model 72). On systems with 3 jet housings and 2 pumps,
check valves MUST be installed at the discharge connections at each pump.
CAUTION: Allow at least 12 hours curing and bonding time. Insufficient curing and bonding times can result in leaks and
flooding.
CAUTION: Throughout the entire installation, make sure the plumbing connected to the BaduStream 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 as close to the jet housing(s) as possible. For systems with 2
or 3 jet housings, install the 6” x 4” reducer bushings as close to the 4” manifold tees as possible. The 6” suction line should
be run from the jet housing(s) 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.
