Pressure washing is a great way to clean your home, driveway or other surfaces. However, it can be easy to put too much pressure on the surface you’re cleaning. This can cause damage to your property and lead to other problems. The increased pressure may be a fault of the machine operator or a fault in its unloader valve that builds too much pressure when not spraying.
If you’re looking for ways to avoid using too much pressure when pressure washing, read on for some tips.
Use a low-pressure nozzle. This will help you avoid damaging your property by using too much force. You should also make sure that you’re using the right nozzle for the right job. For example, if you’re cleaning a wood deck, don’t use a high-pressure nozzle because this could damage the wood and make it impossible to finish with a regular one later on.
Test out different pressures before starting. If you’re not sure what kind of pressure is best for the job at hand, try testing out some different pressures before getting started to get an idea of how each one works on different surfaces and materials.
Don’t aim directly at concrete or brick walls or driveways unless there’s no other way to get them clean without using too much force that could cause damage to their surface or structure. Instead, try spraying them from an angle so that the water comes off at an angle rather than straight down onto these types of surfaces.
Don’t use too much chemical: Pressure washers are designed for removing dirt from hard surfaces like concrete and wood decking. They’re not meant for removing paint or other staining materials from your home’s exterior walls or roof shingles. If you try using a pressure washer on these areas of your home, you may end up damaging them with chemical residue that remains after cleaning is complete. Over time, that can cause serious damage as it works its way into the wood grain of your home’s exterior walls or roof shingles and begins deteriorating them from the inside out over time.
Why would a Pressure Washer Build Pressure When Not in Use?
There are several reasons why your pressure washer builds up pressure while it is not in use. The most common cause of this is a clogged pump filter, which can be easily fixed by cleaning it out.
Other reasons include:
If the pressure washer has been sitting for more than a month, it is possible that some debris has gotten into the pump chamber and needs to be removed. To do this, turn off the water supply and open up your pressure washer’s lid. Use a screwdriver to loosen or remove any screws holding the metal housing onto the pump chamber. Once these are removed, pull off the metal housing from around the pump and remove any dirt or debris inside. You may need to use an old toothbrush to scrub away any buildup on the blades inside of the housing if there is any present.
Another possible reason for high pressure while not in use could be due to excess oil in your engine’s oil reservoir. Excess oil can leak into other engine areas, causing problems like high pressure while not in use. If you suspect this may be happening with your engine, then have it checked over by a mechanic so they can determine what needs repairing before using it.
Another reason why a pressure washer builds pressure when not in use is that there’s something wrong with the seals on your unit’s pump housing cover plate or housing cover seal O-ring seal. This could be due to wear and tear over time or improper servicing procedures when performing maintenance on your machine during its life cycle.
