Worth the extra money
I have put this pump through multiple 12 hour days and it has ran flawlessly. Only one issue so far. The oil cap broke off at the top of the threads but customer service sent one out right away and i’m back at it. If you plan to pressure wash regularly buy a cat pump! I have gone through two other brands very quickly and recommend spending a little more to get one that will last.

You get what you pay for!
You get what you pay for! Yes the price is a bit steep, but this is a legit Cat Pump and on my 11hp older GX340, still works great! Plenty of power and gpm, it does bogg down my motor when I have it on full pressure

Crazy power
This is a legit power washer. Not a big box store model, this thing has thee most power ive ever seen out of a pressure washer. Just make sure you have the engine to support it. I have to GX390. Very impressed. A lot of money but impressed.

Too pricey

Worth the price
It is expensive but imo worth it. We had gone through 4 of the factory General pumps in a year on the PW this was for before i got this pump. We use the PW for about 10-14 hours a day so they get a workout. We've been using this one since aug 2012 and not a single problem yet, including the time one of my guys forgot it outside overnight in temps around 10 degrees. It took a day inside to thaw but the next day it was back to work.

Expensive for junk
Brand new out-of-the-box installed it, turned on the water then started the pump, the crank case filled up with water and it never pumped any water out. I would not refer this pump to anybody

Money maker!
I've been limping along a tired pump on my 13hp Honda...replaced valves and whatnot, but still wasn't right. I looked into a rebuild and found that it would cost me as much as a new pump, without any guarantees... So happy I pulled the trigger, this thing is a beast...CAT pumps rule! And my first job will pay for it... 💪🏼
