How to Identify and Fix Common Gardening Problems ?

The number one cause of low or no pressure when using a pressure washer is a blocked or worn nozzle. Blocked nozzles will prevent water from escaping, while a worn nozzle will allow too much water to pass through, causing the pressure to drop.
The engine of your pressure washer may rev sporadically because it is experiencing an intermittent blockage of the air that it needs to function properly. The first thing that you should do is to check the air filter for clogs caused by debris or dirt. Clean out any clogs that you find and the erratic revving may stop.
Using an old, worn-out nozzle is a common cause of lost pressure, and also has one of the simplest fixes. All you need to do is replace the nozzle and make sure you`re using the proper size. Don`t go by the color of the nozzle, make sure you check the orifice size.
There could be small leaks, holes, or tears in your garden hose or high-pressure hose that are causing your pressure washer to lose pressure when you pull the trigger. If you find leaks, plug the holes or replace the hose, which should solve your pressure issues.
How Do I Tell If My Unloader Valve is Bad? In most occurrences, the first symptom of an unloader valve going bad is no pressure from the wand when the trigger is pressed. This happens when the unloader valve gets stuck open and does not allow water to enter the hose and trigger.
Surging occurs when the pressure is fine and then weakens. It is caused when the flow rate for the pump cannot be supported by the water supply. Problems can mount from there so it is important that it is dealt with as soon as possible.
Direct drive pressure washer pumps run at around 3400 RPM, while belt-drive pressure washer pumps run at about 1,700 RPM. Because the pump runs at half the speed, it won`t get as hot and, in the long run, will last longer.
If it takes two minutes or less, you`ll be fine, since most pressure washers need 2-1/2 gallon per minute to work. To ensure that water circulates unobstructed through the system, check the water inlet filter or screen and clean it of debris. Also, make sure the garden and pressure hoses are kink free.

Honda powwer boss 3000-whenyoupull the handale to spray it kills the engine
Sounds like the unloader (regulator). Try removing the nozzle, the pull the trigger with the engine running. If motor is still running then it could be the Unloader malfunctioning. If you require a new one try a bypass system for the unloader. The bypass will help save the life of the unloader.

1750 psi Electric Pressure Washer: My pressure washer is losing pressure and is pulsa…
If the pressure washer is pulsating then that is a sign of check valve failure. You may be able to clean of replace the check valves. Replacing the head is the wrong way to go. This is completely unnecessary. If you can tell me the model number of your pressure washer then I can assist you better in pointing you in the right direction.
