TROUBLESHOOTING
Use the troubleshooting table below. If problem persists, contact your dealer.
PROBLEM
PROBABLE CAUSE
SOLUTION
Low Pressure
Belt slippage
Make sure the correct belt is used. If the correct belt
is used and the belt is slipping, then tighten. Replace
belt if worn.
Leaky discharge hose
Check connections. Replace hose if worn or
cracking.
Pressure gauge inoperative or
not registering correctly.
Check pressure with new gauge and replace as
needed.
Air leak in inlet plumbing
Use PTFE liquid or tape to seal the threads. Make
certain that the PTFE does not go beyond the last
thread. Doing so may damage the pump.
Inlet suction strainer clogged or
improperly sized
Clear the obstruction, or use adequate size for inlet
pump connection and fluid being pumped.
Relief valve stuck, partially
plugged or improperly sized
Clean and reset relief valve to system pressure and
correct bypass. Check supply tank for
contamination.
Worn or dirty valves
Clean valve or replace with a rebuild kit.
Worn high-pressure seals;
abrasives in pump fluid, severe
cavitation; inadequate water
supply; stressful inlet conditions.
Replace seals with manifold rebuild kit(not service
kit). Install and maintain proper filter, check line size
and flow available to pump
Pulsation pump runs
extremely rough, pressure low
Faulty pulsation dampener (if a
pulsation dampener has been
installed.)
Check pre-charge. Check manufacturer’s literature
on recommended pressure.
Restricted inlet, or air entering
inlet plumbing
Be sure that inlet hose is the proper size. Check
filters and clean as needed. Check fittings and use
PTFE liquid or tape for airtight connection.
Valve or spring damage
Clean or replace valve and spring, check inlet supply
tank for contamination
Seal damage
Replace seals with manifold rebuild kit(not service
kit).
Slight water leakage from
under the manifold
Possible condensation
No fix needed.
Worn low pressure seals
Replace seals with Manifold Service Kit (not Rebuild
Kit), check inlet pressure and inspect ceramic
plunger for damage.
Excessive oil leak between
crankcase and pumping
section
Worn crankcase oil seals
Replace crankcase oil seals.
