r/pressurewashing

My pressure washer can’t maintain full pressure. If I let go of the trigger and pull it again, it gets instantaneous full pressure and immediately reverts back to lower pressure as shown in the video. It happens with all tips and not just the soap tip shown.

I last used it about two months ago and it was operating normally for about an hour and a half and as I was finishing up my cleaning, this problem arose. I pulled out the unloader valve and it appears to be functioning properly. Checked inlet and high pressure holes and checked for debris and still not resolved.

It’s a craftsman 3000 PSI model CMXGWAS020808.

Hello everyone, this is my first post on this sub and my first time really working with pressure washers. I bought a used 3750 psi 4gpm dewalt pressure washer off of marketplace with a gx390 motor. The only problem I have so far is connecting the pump outlet to one end of my hose but they both appear to have male ends. Is there an adapter that would help connect the 2? Not sure what sizes they both are but any help is greatly appreciated.

I have a Honda GX390 4 GPM pressure washer. Would 4% SH and a 25° nozzle be the right approach for cleaning this retaining wall? Any tips or things to watch out for?

Hi Everyone. We have had some very warm, humid weather lately and I believe the siding I washed with Moxie and a pressure washer was as warm as it has ever been.

Any clue as to how to how to clean these blotches on a two story side of the house? I went board by board with vinegar and water on the front and it seemed to have helped. Waiting for the front to dry all the way.

Any help would be GREATLY appreciated. Thanks!

Does the spring inside the pull cord mechanism need replaced if it’s making these clicking sounds? I pull it and when it clicks, it doesn’t retract back into the mechanism afterward, but there’s still tension when I twist it. Thanks to anyone who could help.

The parking garage had a massive fire and an engineer was coming the next week to inspect the concrete and they needed all the black and ash removed in order to inspect the concrete.

So we had a company that made this a lot more complicated than it needed to be, and because of that was not meeting their deadline.

What they were doing, washing and vacuuming every drop at the point of washing using 8 people to shovel the water into trash cans. In one day they filled up 60 trash cans (the larger ones you use for outdoor pickup). They completed 20 percent of the job in three days.

We sent in two guys and got the rest of the job done in 10 hours.

We produced 1 and a half totes of waste water.

What did we do?

We had a drain that sends water to the bottom of the parking garage. We had a tote set where the water was going so it didn't flood the basement. We had charcoal water filters that are 10 feet in length surrounding the water run points to filter the water and slow down the trailing of the water.

This will allow a lot of the water to evaporate. The tool we use to do the final touch ups is a suttner ST36 (I get them from pressure washer products in Clearwater Florida for around 180$) and send the remainder of the sludge into a 55 gallon drum sitting at the mess. Have a drum dolly to move the drum as needed.

A lot of cities are extremely strict, and some customers are even more strict on waste water. When you get into bigger jobs that question you hear of "what do you do with the waste water" gets asked. Well this is one way to do it without having to buy a 20,000$ vacuum system you'll use once every six months. Now if you find yourself cleaning parking garages monthly, I do think they are useful and save a lot of labor.

To give you an idea on the kind of money made on jobs like this, it ended up paying about 450$ an hour and we ended up doing the job for 13 hours total after touch ups and figuring out what to do with the waste water.

Why does it pay a lot? Because there are a lot of obstacles and hazards involved and price is actually less important than "can you just get this done".

Will using chemicals damage the bleach? Also, the stone looks clean already. Am I wrong? Thank you in advance!

Hi, looking for some assistance with my pressure washer. throttle seems so have loosened? struggling to get proper pressure buildup. pressure rises and falls repeatedly

So I washed this pool deck today. It was three years old and told the client I could wash it but obviously it’s not gonna do much as it wasn’t very dirty. So I went ahead and proceeded with a basic wash of pretreating the area and then going over with the surface cleaner. As I thought it wasn’t super dirty I just did one side to begin and see if it made a difference. However after it started drying I noticed these dark gray obvious lines that followed the path of my surface cleaner. I immediately stopped and this is what that side ended up with. I have no idea what happened as this was a routine wash and a setup I had used numerous times on driveways and patios. I had no idea how to even it out I tried resurface cleaning a tile and being as even as possible over the area with 50 percent overpasses but it made no difference. How did this happen, is there something I did wrong, is there any way to fix it? I believe it may have something to do with the way the concrete is. I will attach a before/after and a picture of the unwashed other side.

Coming along nice. Any tips from any fellow customer trailer builders/those who built machines on Predator engines? Would love to hear any advice.

Anyone running a 240V / 2hp pressure washer? After real-world performance and reliability feedback

I'm looking at a Spitwater HP10-090, a single-phase electric cold water unit. Specs are 90 bar (1305 psi), 10 L/min, 2hp 240V motor, 1450 rpm low-speed pump, runs off a standard 10 amp plug.

I do rope access and facade cleaning work, so it'd get used hard and regularly, not just the odd weekend job. Before I commit I want to hear from people who've actually lived with one of these mid-size electric units rather than going off the brochure.

A few things I'm trying to get a read on:

• How's the 2hp motor holding up under sustained use? Any overheating or tripping issues on a 10 amp circuit?
• Is the low-speed 1450 rpm pump actually lasting longer than the high-speed ones, or is that just marketing?
• Real cleaning performance at 90 bar / 10 L/min. Enough grunt for facades, render, and general commercial muck, or do you end up wishing you'd gone bigger?
• Anything that's failed early or been a pain to get parts/service for?

Happy to hear about Spitwater specifically or comparable electric units in this class. Cheers.
