MALFUNCTION 

 

CAUSE 

 

REMEDY 

 

Inability to build up 

pressure…

 

 

 

 

...with high pressure 
gauge fluttering. 

 

with loud noise from 

HP-pump. 
(Low pressure gauge 
reads below 10

”Hg)

 

 

…during navigation

 

 
 

 

Air enters intake plumbing. 

 

Air in intake system 

 

 

High pressure pump valve 
stuck after long storage time. 

 

Seacock closed 

 

Seacock clogged (Barnacles?) 

 

Strainer, filter/s fouled 

 

 

Through hull fitting in wrong 
location (suction trough 
movement). 

 

Tighten all hose clamps. 

 

Allow more time to prime. If no boost pump is 
installed, perform freshwater flush to assist 
priming. 

 

Open one by one all six hexagonal valve covers. 
Inspect valves for movement. 

 

Open seacock 

 

Clean seacock 

 

Clean strainer, change/clean filter/s. 
 
Use strainer scoop (page 11). 
 

 

Pressure drops 
frequently with change 
of noise

 

 

…during navigation

 

 
 

…and drop in pump RPM

 

 

Air enters intake plumbing. 

 

 

Air enters sea water intake 
during navigation. 
 
Magnetic clutch slips 

 

Tighten all hose clamps. Reseal NPT fittings. 

 

 

Move through hull fitting to lower location. 
 
Bad electrical contact. Test voltage directly at 
clutch connection when clutch is engaged. 

 

Excessive leakage 
between the high 
pressure pump head 
and cran

kcase…

 

 

…with water in crankcase

 

 

Worn high pressure seals 

 

Cracked ceramic plunger 

 
 

Cracked ceramic plunger 
and/or worn HP/oil seals 

 

Replace high pressure pump seals 

 

Inspect for hairline crack. Replace plunger  
and HP seals (page 20). 

 

Inspect for hairline crack. Replace plunger (if 
needed), high pressure seals and oil seals. 

 

Product salinity reads 
above 500ppmTDS. 

 

Membrane element has 
reached its service life time. 

 

Replace membrane element. See instructions 
on page 17. 

 

Product output below 
specification. 

 

 

Membrane element clogged 
or reached its service life 
time. 

 

Clean membrane element (page 14). 
Replace membrane element (page 17).

 

 

Leak on pressure vessel 
end cap from salt water 
 

from fresh water 

 

O-ring worn 
 
 
Product port Teflon seal worn 

 

Remove and inspect plug (page 17). Change O-
ring/s as needed. 
 
Remove port, re-seal, install hand tight + ¼ turn
