Pressure Washer Trouble?

Q. I have the water hooked up to the pressure washer and the gun the water shoots out of hooked up as well. I started it up and the water that came out the gun was not as strong as it usually is. I am not sure what the problem is, I have run on and I have the lever towards the rabbit, and it has a full tank of gas. Anyone know what could be causing the gun not to shoot the water out with as much pressure?

Answer
From your description, you have a low priced pressure washer, probably 3 hp engine. There are two possible problems. The pressure relief valve may be leaking by or stuck partly open or the pump may be failing. The pressure relief valve is usually part of the pump, so either problem requires dismantling the pump assembly. Most of the low priced pressure washer pumps are "throw away," not worth repairing. You may be able to buy a replacement pump from the manufacturer, but the cost of the part and shipping is usually more than the washer is worth. Good luck.

Gas and Oil in Honda Pressure washer?

nathan w

I have a Honda GX340 11HP pressure washer. I just had someone get the motor working good and fill all the fluids.

Should I use premium gas or regular? Do I need to mix oil in the gas? How should I store it after my May & June annual pressure washing?

Answer
Regular gas and do not add oil to the gas. Modern pressure washers have 4 stroke engines.

Make sure there is water in the water lines of the pressure washer before running it or you can burn out the pump.

Why does my 6 month old troy built pressure washer stall out when water is hooked to it?

My grandmother passed away recently and I was given her pressure washer... Someone stored it over the winter and it wouldn't start... Carb gummed up. Now it runs like a champ but as soon as I hook water to it it will run and then bog down quickly and die?? I'm good with engines but I don't know where to start with the pump? It's a lowes brand troy built 2550 psi 6hp gas powered model. I've started it a couple of times without the water but never more than a couple of seconds and it was purchased in November... But not properly stored. It looks bran new but I don't know what to do now.

Answer
The throttle speed might be set too low, set the throttle to high.

You might still have carburetor issues, be sure you have enough water feeding the pump.

How to quiet a small gas engine.?

tonymonton

I bought an 11HP Craftsman pressure washer. The engine is a Briggs and Stratton, Intek model. This is an awesome pressure washer. But, it sounds like a dragster (ok I'm exaggerating). I called Briggs tech support and they said they were working on a solution, but it may take 2 years. I will lose a lot of hearing in 2 years, and my neighbors may set my house on fire when I go on vacation (I'm still exaggerating).
I was thinking of running it in my garage with the doors closed and running extra hose. This would probably work, but the risk of Carbon Monoxide poisoning is too great to try it I guess.
So, does anyone know of a solution to this, aside from buying an electric model? I don't want to part with this machine. :(

Answer
Only way to quiet the exhaust is to fabricate a larger and thicker muffler or buy one that is larger that you can modify to fit the original bolt pattern and exhaust port size. I've done it on a few customers lawn equipment and with a skilled tech in welding is not that difficult although somewhat involved in layout and design. If the original muffler for the unit has a piece of pipe coming off it for exhaust, you could try attaching another muffler to it for say a small motorcycle or minibike of the same diameter pipe. Surprised the Briggs people would take that long to come up with a solution.
Another simpler solution is to build an insulated open-top box of plywood and foam insulation board to surround the washer with and direct the sound upwards---open top is necessary as it needs air flow to operate the engine or run it in a shed or garage if possible to deaden the noise. You'd have to ventilate the garage somehow or hook up a heat resistant hose to the exhaust and duct it outside with a blower like auto garages do.

How can i tell what pressure my pressure washer is at?

N/A

I have a 3800 psi dewalt pressure washer and im wanting to turn it down to about 3000-3300 psi but im not sure to tell what psi im at while turning the pressure down.
If anyone could help me out id appreciate it!
Thanks!

Answer
What you would have to do is connect a pressure gauge between the end of the hose and the gun. Run the pressure washer with the gun's trigger pressed so there's water flow and check the pressure it is shooting water. To adjust it to the pressure you want you can either use the unloader to regulate pressure or adjust the engine's rotation which would also regulate pressure.
If you need a gauge here is the link to a 5000 psi one. There are more on the website in case you think this one is too much.

Why I have no pressure on my pressure washer?

Ken H

My pressure washer starts quickly, runs good, but my pressure stopped. Hoses not clogged, have water coming thru wand, but no pressure. How do I fix this?

Answer
If you've ever run the pump without water pressure being on it then you can suck the seals loose. Sometimes they will reseat, other times not.

When you last used it - if it was last year, before winter, and you didn't winterize it the seals may have dried out. Just about all hardware stores carry a seal conditioner for pressure pumps. It lubricates and conditions the seals while also removing water from the pump so if the weather freezes you don't crack the pump housing. I've bought many pressure washers that have experienced this problem. People in my area fail to winterize their pumps and end up with junk. They still have a good engine on them, but the pump must be replaced.

With your pump, check for leaks. If it's not leaking anywhere then that's a good sign. There is a pressure regulator on the outlet side that when there is sufficient pressure the high pressure water is diverted back to the inlet side. That's so the pump doesn't stall the engine or blow the hose.

CAUTION: IF YOU MESS WITH THAT SETTING YOU CAN DAMAGE THE PUMP OR EVEN DAMAGE YOURSELF. YES, YOU CAN GET HURT IF IT'S NOT DONE RIGHT. If you DO remove it, make sure you carefully count the number of turns to put it back exactly as it was before you took it off. There MIGHT be soap residue keeping the pump from building high pressure. The water can be going in circles.

There's a lot to pressure washers you wouldn't think of. These are just a few possibilities.

Best of luck with your project. AND BE CAREFUL.
