In nearly all instances, pump failure is the result of improper installation or operation rather than normal wear. One of the most common causes of pump failure is improper or unnecessary service, often as a result of the operator attempting the service.
Each time the pump is serviced, the chance of pump failure as a result of improper service increases. The operator should be left with no reason or desire to open the pump for service.
Usually requests for service are not made until the operation of the equipment has become so bad that it usually does not work.
'The high pressure pump is generally one of the most dependable and best constructed components in a high pressure cleaner. The well-engineered pump may be installed in a not-so-well engineered system. 'All pumps have wear parts, which eventually need to be replaced.
'In most cases, the high pressure pump is likely to outlast most other components as long as the pump is installed correctly and the system is operated properly.' (This is a quote from 'The Universal Guide to High Pressure and Steam Cleaner Repair.')
Pump chattering caused by heavy cavitation can be mistaken for a broken connecting rod. To determine if cavitation is the source of the problem, open the upstream chemical injector completely while operating the system. If the noise leaves it is cavitation. If the system does not have an upstream injector hook up a positive feed system to the pump and operate the system.
Do not assume that the pump is the problem.

Excessive noise: Hot water Mounting bolts
Cavitation Vibrations in the system
Worn valves Worn O-rings
