Review: Thank you Toolcy and sukie for wonderful customer service - I own my own pressure washing and softwashing business and going through pumps every once in a while is just a part of it . I typically have purchased other brands in the past but when trying to contact customer service it was a miserable experience. Recently I purchased a pump from toolcy. Used it a few times and noticed a leak coming from the sight glass. Although frustrating everyone’s human and things can happen at manufacture. I contacted toolcy and had a customer service agent named Sukie. She provided top quality customer service and replaced my pump but are overnighting it . It’s not always about the issue it’s about how you handle it . When the pump ran fine the pressure was great , the build quality was good (other than a sight glass issue ) and the value for the money is definitely unbeatable. The fit on my dewalt pressure washer was very easy to install and the functionality of the pump is straight forward. I will only be purchasing toolcy from now on and am about to order two more . I would like for them to come out with a 5gpm model.
Review: Glad I bought it - Works well very powerful

### ⭐⭐⭐⭐⭐ new pump easy install
*by B***Y on May 28, 2025*

Bought this pressure washer pump due to its brass corrosion resistant casing along with its ceramic plungers it fits my Honda GX 240 11 hp motor I also bought the pressure washer gauge that plugs in line at 3400 RPMs the machine appears to be putting out 4000 psi from the gauge and drops to 3000 psi on the gauge whenever the pressure wand is engaged, I highly recommend placing anti-seize on the engine shaft after polishing it with Emery cloth and I would coat the key that was supplied with the machine with anti-seize and I would also put anti-seize inside the pump key also anti-seize all the bolts holding this on to the Honda motor we'll be planning on changing the oil after eight hours use and then we'll go to 30 weight synthetic oil. The instructions are very limited and not much data inside the box however you can look it up online. Let's hope it works good if it fails i'll be back with further updates
