Gas Pressure Washer Advantages
One thing is certain – gas pressure washers certainly bring it up a notch when it comes to water cleaning. They are capable of delivering an immense amount of pressurized water to satisfy each one of your cleaning demands. With this being said, let’s take a quick look at some of the major benefits that would make you consider purchasing such a unit.
- The smallest gas pressure washers offer more pressure than the largest electric ones. This means that gas powered pressure washers are capable of providing significantly more pressure than their electric alternative. This makes them perfect for a lot of solutions that electric washers won’t be able to handle, or at least not as effective and as fast.
- Almost all of the units feature a thermal sensor that would follow the temperature in the engine in order to stop it once it gets hot enough. This is why you should never worry about the overheating of a unit like this.
- Some of the machines are capable of delivering up to the unbelievable 7000 PSI or working water pressure which is more than enough to actually carve through thin metal.
- These units are perfect for preparing different surfaces for repainting because you can run them over with the pressure washer in order to get rid of the old covering and simply add the new layer of paint above them.
- They are a lot more stable than electric pressure washers because of their construction. They normally have a welded steel frame to keep the unit from slipping aside or falling.
In any case, the gas pressure washer machines are more useful for commercial and industrial appliances. They are great for cleaning different types of agricultural machinery or large driveways in front of a factory, for instance. They are going to get this job done a lot faster and tenfold more effective than the best electric washer. On the other hand, it is safe to say that they are also usable in residential conditions but it is not their main designation.
Troubleshooting Common Gas Pressure Washer Problems
Like any device that includes an engine and other complicated internal components, it is highly likely that you are going to have some issues with the gas pressure washer at some points. This is why we are going to present you with a list of some of the most common problems and the most appropriate solution for them.
Chattering pressure washer pump.
The reason for this might hide between the fact that you have a bent or damaged inlet line or the water supply might be too low. However, don’t worry because fixing this is rather simple but you would have to make sure to check the water supply. Don’t let the water supply be low for a prolonged period of time. Another cause for this might be the fact that the water is too hot or you have air in the pump system. On the other hand, if the washer pump is only vibrating but not chattering it is likely that you have air in the system of some debris that has polluted the valves.
Leaking pressure washer.
The most common reason for this is a worn out seal. There are a lot of seals that are properly distributed throughout the entire design of the pressure washer and if any one of them cracks and fails it is likely to lead to some sort of leakage. On the other hand, you might be experiencing oil leakage. You have to make sure that you check out your seals at least twice a year if you want to be sure that everything is working as intended. Another reason for the leakage might be worn out plungers or if they are broken. If you find such a component it is inevitable to replace it if you want your device to work.
Pulsating water pressure.
This is almost always caused by a dirty inlet or a discharge valve. You can clean those after several uses which is close to being mandatory if you are washing wooden surfaces. You can also have a stuck plunger for a lot of different reasons and in any case, you should make sure to properly clean those components.
Spontaneous shut-off of the pressure washer.
There are two main reasons for which the engine is going to shut off after continuous use – either you have run out of fuel or you have run out of oil. In both cases, you are going to experience an almost instantaneous shut-off of your engine. A good way to get rid of this problem is to check your fuel and oil levels before you start using the device. You can make this a habit and you would never have to worry about running out of fuel or oil again.
In any case, it is a lot better to catch the problem early and deal with it before it has done any more damage to your device. This is why you should keep a close eye on your washer on a regular basis in order to avoid expensive repair work.
The best gas pressure washer is ideal for satisfying literally all kinds of cleaning demands. Not only that, it is perfect for preparing different surfaces for renovation and repainting. This is due to the fact that the high water pressure they are able to deliver is going to peel off the older layer and let you lay the newer one on top of it. In any case, getting the right device is not always a walk in the park especially if you have no idea of what are you looking for. Therefore, these specifically chosen gas pressure washer reviews are here to enlighten you and make your life easier in this particular matter. Keep in mind that these units are a bit more expensive than electric pressure washers and you certainly don’t want to buy a unit that won’t do you any good.
