PSI(pounds per square inch):A pressure washer’ PSI rating is the maximum amount of force (pressure ) discharged by the pressure washer .The higher the PSI, the more cleaning power available and the more things you will be able to clean . GPM(gallons per minute):A pressure washer’s GPM rating refers to the water flow during one minute of operation . The higher the GPM , the faster you will be able to clean . Operator errors of high pressure washer that will cost you much money Cause 1. Running the pressure washer without water Normally this will destroy the pressure water pump within minutes. Cause 2.Running the pressure washer in extended by-pass By-pass is when the pressure in on , and the trigger is off the water is re-circulating inside the pump manifold , the water temperature builds as time goes on . It is not allow to lets the unit run in by-pas for more than five minutes . This is because the heat buildup quickly damages the pump. Therefore , you have to run off the pressure washer every time you are not going to be spraying , even for some unit that installed with a thermal relief valve that will release the hot water and the pump feed with cold water to cooling down . Cause 3.Cavitation                                                                                                       Cavitation is caused by air getting into your pump . The air can damage your pump as it rapidly expands and contracts . The first sign of cavitation is loss of pressure and a hammering noise. The cause of cavitation is lack of water or air getting into the system .For example , your pressure washer is rated for 4.0GPM but the inlet hoes only provides 3 GPM, then the pressure washer pump will try to pumping 4.0GPM.The suction due to the lack of water will pull in air and cause cavitation. The only solution to cavitaion is to feed your pump the required amount of water and to make sure there are no leaks in the water inlet system . Cause 4.Freezing In the winter the water left in the pump after use will freeze and possibility of damage to the pump .The typical remedy for this is putting anti-freeze in the pump .So always keep the pump run for a extra seconds and pump our the excess water . Cause 5.No lubrication and lack of lubrication High-pressure pumps, like gasoline engines , required oil to lubricate transmission mechanism , the crankshaft, connecting rod and plungers . The oil is needed to keep the pump parts cool and turning freely . No oil and low oil will causes permanent damage to the pump. When the oil leak out , or water gets into the pump oil , the pump parts will overheat and begin to break apart. Always check your oil level and maintain the correct amount and type of oil in the pump to prevent damage .   The kind of high pressure washer 1.
