PRESSURE WASHER TROUBLE SHOOTER
       Tech Tips and Troubleshooting
 

       Listed below is the problem you selected with causes, solutions and discussion

HIGH INLET PRESSURE

Test inlet pressure.

Install regulator if needed

 Most residential buildings have pressure regulators on the water supply, limiting the pressure to less than 75 PSI or less.  This is a good pressure for the average pressure washer pump.  

Some buildings do not regulate the PSI so inlet pressure can exceed the specifications of the pump.  Excessive inlet PSI can push water past the low pressure seals and into the crankcase, causing the oil to go milky.  See index for "milky oil"

If you are working in areas where inlet pressures are not regulated or fluctuate you can always install a pressure regulator on the supply or inlet of the pump. 

Check the specifications of your pump for recommended inlet pressure. 

 SOME OF THESE OPERATIONS CAN BE EXTREMELY DANGEROUS.  IF YOU DO NOT HAVE SUFFICIENT TRAINING IN THESE PROCEDURES, WE RECOMMEND YOU SEEK ASSISTANCE FROM A
