    • The little pump that could
Reliable. I've had this pump for 10 years now, and every other year we get hit with a hurricane, and this thing runs and runs and runs. in the rain, half submerged in water, doesn't matter, it just fires up and goes. only downside is the gas tank is small, so run time is usually under 2 hours. but its worth every penny. 10 year update: finally starting to have a small fuel leak in the carb. after 10 years of no maintenance, honestly surprised it still runs so good! I would happily buy a second one if they come back in stock. ... show more

    • Great little pump
Ran it about 50hrs so far right out of the box. Other then the fuel tank being small and only running about an hour and a half it’s a great purchase for the price.

    • This product is garbage
Crap, never worked. Came bent, made minor repairs and broke after using a few hours. Will never buy used from AMAZON again. Thought with a company of known quality used equipment would be almost as good as new. My mistake that I tried to fix and I dont want to go thru warranty void issues and would rather learn from my mistake. Don’t buy this product new or used. 400 plus bucks down the water drain(which works better than this pump) . Spend a little more and avoid the frustration ... show more

    • Runs hard and long
Best pump I’ve ever owned. This is my second one, the first lasted 4years after several long weeks of straight pumping on a regular basis. You’ve got to watch out for product damage when shipping . My new one came with frame bent and buckled but pump is in good condition.

    • Intake flapper broke off at 80 hours, Pump failed at 500 hours, engine flawless

I was happy with this pump. The engine starts easy and runs well. Then at 80 hours runtime, the pump wouldn't prime. The suction intake flapper valve broke off. The flapper valve is a disc of steel encased in rubber. The rubber surrounding the flapper valve, the hinge and the gasket that seals the fitting is all one piece of soft rubber. I'm surprised it lasted this long. It WILL break, it's just a matter of time. Also, in my case water and mud got inside the rubber casing surrounding the steel flapper plate and deformed the rubber. It never held the prime water in very long. Anyway, parts break, things happen, I'll fix it... You can't buy parts for this pump. I called Duromax. They won't honor the warranty because I bought it here, on Amazon. The service rep said to start a return on Amazon and it would get to them.. Amazon return flat out said this item is not returnable. That's it, end of story. Sold and shipped by Amazon Services LLC, so no third party shadiness either. One month and a failure that makes the pump useless. Duromax WILL NOT EVEN SELL YOU THE PART. The flapper valve gasket is part number is DS40-32030 and is only obtainable through their warranty. [Update 12/30/2021] I called Duromax again and got a different rep. This one just asked me to email him a copy of my Amazon receipt and description of the problem and a new flapper valve should be on the way now. Still, I've found this pump to be sold by local big box stores. If you have one of those nearby, maybe buy it there so you have a convenient place to return it if Amazon or Duromax doesn't feel like cooperating today. [Update 1/21/2022] Still no replacement flapper valve gasket. I have purchased a 4" foot valve for the submerged end of my suction hose here on Amazon for $150. This should allow me to fill the suction hose and pump housing with water to prime it. The foot valve is cast iron and standard parts so easy fix when the seal wears out. It's too bad weak/consumable parts are not available for this pump. My recommendation of buy it somewhere you can return it stands. Duromax and Amazon did NOT honor their warranty. In the pictures I've posted, you can see the small rubber tabs at the top of the round flapper valve. That is all that's holding the valve on. [Update 5/9/2022] Duromax did eventually make good on their warranty, the replacement flapper valve arrived today. 5 months after I called them. Sadly the pump has other issues at this point and the replacement valve arrived too late to be of any use to me. The pump is at 500 hours runtime on my meter. Everything was working fine with my addition of the extra foot valve until today. I noticed the flow was low and see the pump is leaking water externally. It looks like the cast aluminum pump housing is cracked or the impeller failed. I'm going to disassemble it to see what happened. Safe to say it's done for. The engine half.. spectacular. 500 hours runtime and never missed a beat. Starts first pull, every time. I've run it nonstop for weeks connected to external fuel tanks. I've changed the oil probably 5 times and have been using 15w40 (what I have handy). 5 stars on the engine. I guess my final verdict would be it's a good value if you get it at $300 which it's currently on sale for. You will also have to buy an additional foot valve for your suction hose. 500 hours of pumping for $300 is not bad. I just bought another one. ... show more

    • Great Customer Service!
Flapper Valve Gasket failed after 4 months of regular use. Called customer service and emailed a proof of purchase. They sent me a brand new pump, only had to pay shipping . Got to keep the other pump for parts. Excellent service experience!
