How much pressure is enough to clean your outside projects? 3000 PSI? 4000 PSI? Is that much pressure even safe on your expensive property? If you are anything like I was when I began researching you would probably think to yourself, “4000 PSI must be where it’s at!” But the truth is, for most people, that much pressure isn’t good for anything but sandblasting your name in concrete or ripping off old paint. Maybe it’s a conspiracy to promote professional power washing companies who have the accessories for their tools that can utilize high pressure in the right situation. Buy the right situation I mean cleaning stone, concrete or masonry with turbo rotary nozzles or centrifugal surface cleaners. Just imagine that much pressure 12 inches away from your largest investment, blasting away every thing it comes in contact to including the top layer of your siding, soffit or foundation. This, unfortunately, is really the way may homes today are cleaned.Annapolis Brothers Powerwashing
So, what are the benefits of low pressure washing? When the right chemicals are mixed with your low pressure water, you’ll find that the dirt and grime will break loose within minutes and all while your house is safe from high pressure water blasted behind your siding and soffit. The best part is that almost all the cleaning can be performed from the ground. The correct nozzles, that attach to your spray gun,are key to your low presser set up. Nozzles with larger orifices increase the volume of water and lessen the pressure which opens the valve to allow the chemical to mix with the out-flow of water. For this you need to buy or rent a chemical injector. After the chemicals have loosened up they are rinsed off with either a smaller hole nozzle, for slightly higher pressure that will close the ball valve and stop the chemical, or remove your down stream chemical injector hose from your chemical bucket still using your large orifice chemical nozzle. They will work on any pressure washer, but you will achieve your best results with one that puts out more water. More water equals more cleaning, just at safe low pressure.
There are several companies out there that can help you to find the correct nozzles and chemicals for the pressure washing machine you own or rent. I’ve found that low pressure cleaning insures that your investment will continue to maintain its value for years to come. Next time you think of cleaning your houses’ siding and gutters you’ll know what questions to ask yourself or your service provider and hopefully see the benefit of low pressure washing for yourself.
