Easy installation. Used more than 4 hours after installing with no issues. Works better than the pump I replaced. Cheaper than rebuilding the old pump!

I decided to purchase this pump because it has the feature of adding oil to the pump when needed or when flushing the pump and refilling. So far, it has operated very nicely and puts out a constant 2700 to 3000 psi. This pump does required a heavy gear oil like 80W90 instead of the high pressure pump oil that most manufactures recommend using. This pump was easy to hook up to my 6.5HP engine, and operates it very nicely.

I replaced a worn-out pump on my rig with this one. I can not speak to longevity but over 3 months now of heavy use, it works perfectly for me. The price is hard to beat.

I bought the oil replaceable and there are no instructions included for this type of pump included. I installed the pump, filled with 85w90, primed it and started it up. It only reached 2000psi and when I pulled the trigger on the wand pressure dropped to 1000psi, not the 3400psi as advertised. I contacted their customer service to find out how to adjust the unloader but the picture and instructions I received was that of the thermal release valve. Here us what they sent:Thanks for your contact.To confirm the exact problem and provide you with the best solution, please provide the below information first.1. The brand and model number of your pressure washer;2. Please send us clear pictures of the pressure you measured when you release the trigger and pull the trigger;3. Please also help to send us clear pictures of the pump when it is installed with the pressure washer, and then take the pump off and send us some clear pictures of the pump inside;And here are the steps to adjust the pressure, you also can first try to adjust it to check if it can help to address the issue:Face to the Unloader ValveStep 1Small Nut (outside)Hold small nut with hex keyStep2Big Nut (Inside)rotate very little at 15 degrees：Counterclockwise it will reduce the pressure,Clockwise to increase pressure.Step3Small Nut (outside)Tight small nut touch bigger nut makes sure Big Nut is also tightened by spring.I also attach a picture for reference.Looking forward to your reply.Sincerely,LynSince there is no model number to be found anywhere and I bought a Yamatic from them why ask for the make, this is ridiculous. I have since been able to figure this out on my own and it seems to be working as it should. Only time will tell.
