TOOLCY 1" Shaft Pressure Washer Pump 4400 PSI with Adjustment Unloader

Needed to replace my pump on my predator 4400 4.2 gpm. This pump was very easy to install on my machine. Just watch a video if you’re unsure, you can find it. When I was sure it was attached correctly I fired er up and it was working GREAT! I’ve only used it lightly multiple days in a row so far so take that for what it is but it works with this machine. Good for a backup pump too

Perfect fit for our older model Craftsman pressure washer. Works great! Love it!

My pressure washer stopped working. I thought it was time to throw it away, but then I just simply typed in 1 inch pressure washer pump. I looked at the mounting holes the original one and it worked perfectly. Couldn't have been more happier with this product.

I did not know what to expect. However, it was exactly what I needed. It was to replace, used worn out one, and it bolted right up to the motor. All the parts needed were included. It was pretty much, install the bolts fired up and use it. It was nice that it came with oil and I did not experience any leakage. I did not have to do any. Type of adjustment after the installation. The money paid. Is definitely acceptable for the product. In fact, I thought the pump was a better quality than what I was expecting for what I paid. This was a replacement, and it bolted, right on.

If you're handy with mechanical things, this job is doable. If doing this for someone else, be advised that removing your old pump is seriously difficult so charge appropriately. Now, here's what I found: The pump arrived fast and damage-free being packed great in form fitting foam. First problem was that the included 1 page "manual" didn't say what type oil is recommended. Because it comes with oil already installed, that won't immediately be a problem but it shows me the incompetence of the manufacturer. Second problem: Before I installed it, I wanted to adjust the unloader down to a low setting because the new pump's PSI rating is higher than my old pump. The unloader handle would not turn by hand so I put a cloth rag over the handle and used channel locks to loosen it. That worked and showed what had happened at the factory. They obviously used some kind of power tool and tightened the unloader handle over top of the master adjustment ring with the setscrew locked down. It was so tight over the adjusting ring that you couldn't even see the ring. To fix, I oiled the threads, loosened the allen screw, tightened the adjustment ring all the way down to the bottom tight, and reinstalled the handle. Works great. This pump does NOT put out the pressure that they say it does but it's good enough for me. My 13 HP engine couldn't take much more anyhow so that works out. By adjusting the unloader down too hard, you can work your engine to the point of destruction so be careful. If you have less than a 13 HP engine, use caution adjusting the unloader down too hard. At the very least it will cause the engine to kick back when trying to start it and that could hurt you when pull starting the engine. Other points: with the pump off, lightly sand the rust off of the engine shaft using 120 grit sand paper. Wipe clean then coat the shaft with 'never seize" that you can get at any local auto parts store. You only need a tiny amount. Why? When you pull your old pump off, you'll know why. It took me hours and hours to get the rusted engine shaft loose from the pump coupler. I never want to do that again. The pump comes with a key but you don't have to use it and you don't need to use the setscrew that locks down the key to the key-way - that's optional. It comes with new bolts but just use your old ones if they're in good shape. If the new pump will not pump at first, take out your tip from the wand, start your engine, then press your handle to run water through the hose and wand. When running clear, use your pressure washer's instructions to install a new/different tip because your hose/wand/tip may have been clogged. Don't run the new pump too hard right at first. It's basically a 3 cylinder car engine in reverse so break it in slowly.

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.

I would not recommend this pump. It was advertised as 4,400 PSI, but after just two uses, it stopped delivering the promised pressure. It worked the first time, but on the second use the pressure dropped significantly, making it almost unusable. This product failed far too quickly and appears to be very poor quality. I expected it to last much longer than two uses. Very disappointed with this purchase.

I'm new to the pressure washing business, my stock, 4400PSI 4.2GPM Predator pressure washer stock triplex pump failed on me. I don't have a large budget to purchase the name brand replacement pumps so I took my time and combed through more budget friendly pumps. I settled on the Toolcy because I liked what I seen from others. Well I cannot say enough about this pump. First off the cost 1000% in anyone budget, the replacement process was elementary, the pump fit 100% perfect and the power from this pump is out of this world. I use the glycerin gauge to set the pressure and the needle on the gauge never feathered or vibrated. It was rock solid the entire time. For anybody looking for a replacement pump, do yourself a favor and look into this product because you will not be disappointed! My only recommendation is maybe put a rubber gasket between the brass garden hose connection to whatever hose connection you use.

Incredible pump!! Killer pressure, arrived in perfect condition - this will take my pressure washing to the next level Attached to 9HP Honda engine 10/10 would recommend!!
