This pump mounted easy and does surprisingly well, better even than the AAA pump that came with the pressure washer. Not sure about longevity yet, but I’ve already put probably 6 to 7 hours on it. Nonstop with no issues.

Works great easy to install only 4 stars because chemical injector didn’t work so I plug it and ran one off the pump

I bought this in Oct to replace my other pump and the first 2 times I used it it was flawless worked like a dream. Took it out yesterday to do a job and it won't build up pressure. I can't get up with the company either. I gave it 2 stars only because it worked extremely well the first few times. Kinda disappointed now I have to buy another pump before my jobs roll in.*************UPDATE [After the above review Toolcy reached out to me and after exhaustive trouble shooting they were very willing to make good on their product. I haven't yet installed the new pump because it's rained a lot lately but I'm confident that the original pump was just a one of, machines are mechanical and they break. I want to thank Toolcy for their great customer service and I look forward to getting my machine back in service and making some money. Toolcy you have won a customer for life. Thank you ]

Never buy anything from TOOLCY I bought this pump and when I opened it it was damaged. I tried communicating with Amazon Customer Service and they can’t even do anything about that, I went to the website page and you can’t communicate with them, they don’t have any customer service page. Not the very best, the better thing to do is to pay a little more and get a place that they actually care about what their customers have to say 😡😡🤬🤬

I had a North Star pump on my 13 hp Honda and it had two patterns to put different pump flanges on it was larger out of the pump fit well with the hard ware to bolt it up it came with oil In it , it was pretty much remove old and replace with the new one and prime the pump like normal I have pressure gauge to show the pressure coming out and wow instant 3500 psi with no problem, it came with multiple tips in the kit , and hold on when you pull the trigger it will toss you back just a bit and them game on blast away, it’s worth the money!
