With the great strides made today in technology, washing your decking, house or driveway with a pressure washer seems like the right thing to do. In as much as a regular garden hose, detergent and a little elbow grease might get the job done, a pressure washer does the task incredibly fast. Pressure washers are tools which few appreciate their use until they get to see them at work. Just as the name suggests, relieves the everyday pressure on various chores. A garden hose can be used when degreasing your grill, cleaning out your patio furniture before storage and removing grease stains from your garage store. The importance of pressure washers cannot be overlooked today when cleaning unreachable areas.
How does It Work?
Water enters the machine at a low pressure then the electric motor pushes it through the hose which sprays the nozzle tip at high pressure. This process works great when cleaning stuff around the home that your garden hose is unable to. There are also heavy duty washers which are used for commercial purposes.
What PSI (Rate of water flow in terms of “pounds per square inch”) do you need?
When grading pressure, washers are ranked based on a pounds-per-square-inch scale. A typical garden hose usually draws out under 40PSI while the coin-operated car washes release 700PSI. Now, the heavy duty gas/petrol powered pressure washer dispenses water at several thousands of PSI.
PSI is not the only consideration, the rate of flowing water also matters which is measured per minute, in the liters. The greater the rate of water flow and PSI, the more effective you’re cleaning will be. The larger the job to be tackled, the more the pressure required. Smaller and less significant jobs around your home and electric pressure washers running on 1500-2000PSI can handle larger domestic tasks more regularly.
Do Pressure Washers arrive with Additional Accessories?
Good petrol pressure washers standardized but arrive with additional accessories for any potential adjustments.
- The nozzles which allow water sprayed to be accommodative of the task at hand.
- A lance and power gun
- Wheels which allow you to maneuver.
When using a pressure washer remember that it is a powerful machine which can carve out your name on a word deck or break a closed window, When carelessly used they can afflict injury especially when pointed at someone. Most washers arrive with tips which deliver varied spray patterns. It’s advisable to consider that the tip which provides the least aggression and can get your job done. The 40 degree nozzle provides the best spray pattern when tested on a small portion of its surface.
Complex Terms used to Gauge the Performance of Pressure Washers
- Cleaning Unit abbreviated as CU is arrived at by multiplying the GPM by the PSI. This means that the higher the value of the CU, the higher cleaning potential in a pressure washer.
- Pounds per square inch are at times abbreviated as PSI. This is the highest force discharge potential on your pressure washer. The higher the PSI, the greater cleaning power meaning you can clean a lot more.
- Gallons per minute which is abbreviated as GPM, refers to the rate of water flow in a single minute when the pump is operational. The more the value, the quicker you shall be able to clean.
Common Operational Errors Performed by Pressure Washer Users that are Costly
Free Run – There are some people who run the pressure washers when water is not running. Beware that doing this destroys your pressure washer within a matter of minutes.
Also running the pressure washers in what can be referred to as extended by-pass – In this situation the pressure remains on while the trigger is off. The heated water keeps recirculating inside the pump. It’s advisable not to let this condition continue for more than five minutes as the heat which builds up seriously damages our water pump. So anytime you will not be spraying, allow it to run off.
Cavitation – Cavitation is whereby air accumulation within your pump causes damage due to the rapid contraction and expansion. Cavitation is brought about by pressure loss and the hammering noise. Cavitation is mainly brought about by water being unable to get into its system. A practical example is where your pressure washer has a rating of 4GPM and its only being provided with GPM on its inlet. It will automatically attempt to pump the 4GPM. The inadequate water forces the pump to conduct a strong suction which will also draw in air resulting into cavitation. Having the right amount of water will ensure that there are few leaks within its inlet system.
Freezing – During winter, if water is left within the pump there is a possibility of it damaging the pump. The best way to remedy such a situation is to insert anti-freeze capabilities within the pump. After use, run the pump for several extra seconds to ensure any extra water within is pumped out.
Poor lubrication – The gas/petrol powered pumps which operate under high pressure require oil for frequent maintenance. Their plungers, crankshaft and connecting rods need lubrication oil failure to which results in your pump getting damaged. An oil leak results in some parts of the pump overheating and starting to break apart. Frequently check your oil levels to ensure this does not become the case.
