Of course, you can use the stream function on your vehicle to get rid of stubborn dirt or to get too hard to reach areas. A concrete driveway can be given new lease of life when given a good clean with a pressure washer, and then sealed. Be careful, especially when cleaning pathways as the mortar between the path stones can be damaged when pressure washing. A typical pressure of between PSI should be used on pathways.
Make sure that the wooden surface has been treated before washing, this will prevent the wood from going rotten. Be aware when washing chipboard wood a pressure washer can cut holes into this type of wood because of its brittle nature, it is advised that you avoid pressure washing this type of wood and instead use a hose and stiff brush. A specialist pressure washer can have a pressure of more than PSI but does require very careful use as these machines are used to remove products like paint, ingrained oil, and embedded grease.
As we can see choosing the correct pressure for the object or area you are cleaning is very important. Stuart loves blogging about his hobbies and passions. Living the Outdoor Life is a place for him to share what he learns while creating his perfect outdoor space. Louvered Pergolas take everything that makes a typical pergola great but makes it better with. Different design pumps are available that can achieve the same PSI and flow rates, inherent in the design are tradeoffs that affect cost and durability and this means pumps vary greatly in their lifetime.
Make your decision on PSI and Flow Rate alone and you may choose a machine that can do the job but may be taken through its design life far quicker than you expected.
Entry level pump that uses a wobble plate connected to the drive shaft to push pistons back and forth creating suction before pushing the water out. The pumps drive shaft is coupled directly to the engines drive shaft and runs at the same RPM as the engine. Pros: No seals moving back and forth with piston, self-priming, can produce high pressures. Cons: Many moving parts add complexity, low flow.
Fully sealed. High RPM means they run hotter. Not as efficient as triplex pump. Professional level pumps that are similar in design to your car engine crankshaft, connecting rods to drive positive action pistons to suck in water and then push out water with each stroke. Their life span is basically limited only by how well you maintain them. The easy to access pump head and easy to replace valves make repair and maintenance economical.
Pros: Very efficient. Stationary seal means increased life, less prone to leaks and much higher pressures and flow rates. Lower operating speed allows it to run cool and this again increases operating life. Electric are user friendly and cost effective. The main drawback is you are restricted by length of the power cord, lower pressure and flow.
Petrol machines will go anywhere and offer higher pressure, flow and durability. Cold water washers are great for most applications. In some circumstances where grease, oil, food waste or tough dirt need a little more persuasion, hot water washers can be the answer. When you release the trigger the throttle control reduces the engine RPM to idle. This reduces engine wear and conserves fuel. At the same time the pump is in by-pass with water being redirected within the pump head.
With lower RPM the heat and pressure in the head are reduced also limiting wear, increasing life and reducing the risk of the thermal pressure relief valve releasing. Puncture Proof Solid Treaded Tyres. Great for professionals, gives you all the grip you need in all terrain, wet and muddy areas.
No pneumatic tube and cannot be punctured or deflated. Some models feature a detergent tank that is attached to the frame with a convenient tube to connect the siphon barb on the pump. Can be either one or two-piece, Saber guns are tough, ergonomic and paired to the machine. When replacing the gun be sure to get a gun with the right pressure rating to suit your machine.
As the name suggests, these hoses have steel wire integrated in to the tube for reinforcement. This improves the burst pressure and increases durability and reduces the possibly of kinks. Professionals should not use all poly pressure rated hoses. This choice depends on your application and site requirements. Portable zero gravity steel frames are very tough and great for maneuverability while still being light enough to pick up and throw on a ute.
For commercial and industrial or some specific sites a full roll cage with 4 wheels may be required. The pressure and cleaning actions produced by the washer is dependent on the nozzle orifice and fan size. Rotary Nozzles and Turbo Nozzles. Rotary nozzles produce a rotating and pulsating conical spray, which increases the cleaning efficiency of your water blaster.
This nozzle is ideal for the heavy duty cleaning of wide, flat areas like driveways, flooring, roof tops, brickwork and stripping paint.

We chose an electric-powered, medium-duty pressure washer rated at 2, PSI, because we figured it would be the most versatile for home and garden use, and we have been quite happy with our choice.
The pressure washer even removed baked-on grease from the cast iron grates of our grill. And of course, whenever those outdoor carpets start to look a little dingy, we bring out the trusty pressure washer. Disclosure: BobVila. You agree that BobVila. All rights reserved.
