PLUMBING
• SHURfIo 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. Retail pump kits
include two 3
/4"
swivel barb fittings (straight/
elbow) and an adapter to connect a standard
garden hose to the pump outlet fitting.
• Avoid any sharp radius in tubing that may kink
over time. Route tubing away from any heat
(exhaust manifolds etc.) and fasten securely.
• Inlet tubing (1/2"I.D. min.) from the sea-cock
valve to the pump should be rated for
vacuum. If rigid pipe is utilized, SHURfIo
recommends that the pump inlet port be
plumbed with 1 ft. [.3M] of flexible tubing.
Standard garden hose is not suitable as inlet
tubing as it may collapse under vacuum,
reducing water flow.
• The pump outlet port should not be connected
to rigid (plastic) pipe. Normal oscillation of the
pump may transmit through rigid plumbing
causing noise and possibly loosen or crack
components. A 1ft. [.3m] length of flexible high
pressure tubing is suggested.
STRAINER / FILTRATION
A wash-down system is only as dependable as
the water available to pump. A strainer with
adequate capacity to trap debris must be part
of the system. Screen with a maximum hole
size of .025" [0.6mm] (#40 mesh) with a total
filtration area of 7 sq. in. [45 cm 2] or larger
provides sufficient capacity under most on
conditions. The interval for cleaning will be
determined by the amount of debris
encountered. Check the strainer before and
after each use. Failure due to debris will not
be covered under warranty.
CAUTION: The strainer must be mounted above
the outside water line to prevent water from
siphoning during cleaning, without closing the
sea-cock valve. Mount the strainer where it
can be inspected and cleaned easily.
NOTES:
• To prevent cavitation, through hull fittings should be
located at least 12 in. off the center line of the water
pick-up for the motor.
• The through hull fitting should have a sea-cock
valve to shut-off in case of an emergency.
• Always use high quality non-corrosive fittings, valves
and hardware to assure long term reliability.
• Properly seal all pipe threads before the strainer to
prevent unforeseen leaks.
Never use Teflon tape
or sealing compounds on pump threads. Sealer
may enter the pump causing a failure not covered
under warranty.
