Can this pull water from a holding tank or is it strictly work off pressure coming out of hose??

Asked by: Bez
A hose is best and recommended. The pressure washer must have at least 5 gallons per minute or 20 PSI water coming into the system.

Honda GX390 4,200 PSI 4 GPM Belt Drive Gas Pressure Washer is rated 3.8 out of 5 by 25.

My first Honda engine with any type of problem. Ship to store not a great experience, as the freight company to my locale did it promptly, but then the shipment disappears into a black hole until the store finally gets it, unpacks it and notifies you. Would never compete with Amazon.

Product It was delivered on time and was in perfect condition when it arrived. It is extremely powerful while cleaning a wooden fence and cleaned white siding. I would like to know if Dewalt offers a recommended surface cleaner for driveways.

Rated 4 out of 5 by from very good homeowner unit Bulletproof engine and belt drive to reduce the temperature and vibrations at the pump. But last years model had an external pressure relief system. This one is internal and that was a surprise to me. They also switched from a general pump to something else, and the general is known for its forgiveness in not scavenging the supply hose if the flow is inadequate. Still, for the money, its the best belt drive out there. It also has no external incoming water filter, and that is something I find mandatory. Its only a few bucks to add so its not a deal breaker.

Rated 4 out of 5 by from Very Powerful, good value After 20 years of light use, my 3200 psi pressure gave it up. The new De Walt pressure washer has plenty of power and was easy to assemble. I went with the belt driven model in hopes of extending the life of the pump, which has been weak link in a pressure washer. I also purchased the garden hose inlet filter as additional insurance. Very pleased with the purchase. Would have given it five stars, but the instructions clearly state not to use chlorine bleach products as a cleaning agent, so I was unable to use my Jomax-bleach solution that is really needed for mold and mildew on the Texas Gulf coast. The ZEP pressure washer safe siding cleaner does not get the job done. When using an 18 foot telescoping wand, the pressure needed to remove mold and mildew without a bleach solution makes control unwieldy.
