2500 PSI Gas Pressure Washer

Experienced gardeners share their insights in answering this question :
Common problem. The water admitance valve is stuck in the bore. The valve lets in more water when pressure drops and when wand is closed the pressure builds and the incoming water is blocked. Remove the valve spool and clean the bore with crocus cloth on a dowel rod. Replace the O Rings and lube with plumber’s grease and re-assemble. Often you can buy an O Ring kit for the unit. Deposits build up and stick the valve spool at the high pressure end. The valve is usually crossways to the shaft and right where the water input is connected.

How to Identify and Fix Common Gardening Problems ?

We provide a variety of viewpoints on how to identify and fix common gardening problems. Our sources include academic articles, blog posts, and personal essays from experienced gardeners :

No water jet from the nozzle of the pressure washer > check if the nozzle itself is not clogged – if this is the case, clean or replace it. Also check if the water mains tap is correctly opened and that there is no problem in the flow of the suction hose.
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 most probable cause is a clogged pump filter. The pump filter should be cleaned every three months or when it`s clogged. This filter is installed to catch foreign objects like buttons or coins, and to prevent these items from entering the drain hose.
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.
Never start or run your pressure washer without water flowing through the pump. Running a pump when dry can destroy it in a few seconds.
While pressure washers can deliver between 1,300 and 3,200 psi of pressure, they only require about 20 psi of water pressure to enter the equipment through that garden hose to operate properly. Since most home spigots will provide approximately 30 psi to 40 psi of water pressure, this would not normally be a problem.

Kranzle electric washer will not suck up soap
ANSWER : Hi, if it has a chemical injector on the machine then the pressure at the lance will have to be lowered for it to pull in soap. it works on a similar principle to how carburetors on cars pull in fuel, bernouli principle. high pressure at one side of an orifice going to low pressure at the other side which causes a negative pressure ( vacuum) which should pull in the soap. there should be a non return valve at the orifice (hole) which prevents the water back feeding into the soap container, it is quite common for this valve to get stuck, it is just a ball, spring and o ring , and the ball sticks to the o ring. if it is this system then take the soap pick up pipe off the injector and just push the ball off it’s seat with a bit of wire.If it is a high pressure soap system then that is different, but they usually work with an injector in my experience.try taking the high pressure hose off the front off the machine and running it, if it has an injector on it it should pull in plenty off soap.hope this helps ,andy
