Buying Advice Pressure Washer

[_RaT_]

I know there are folks with less then ideal water deliveries. A pressure washer using 2.5 to 4.5 GPM (the typical range of pressure washers) is still a very small flow compared to an open hose which can vary from about 10 GPM to 25 GPM depending on hose size, pressure and whether you are using a garden valve or hose bib. If your well etc supplies less then what your pressure washer uses, that will be a problem, but then, so will taking an extended shower unless you have water saver heads that drop the flow down.

A 2.5 GPM washer is OK, but if you do much in the way of pressure washing, you will quickly find that that flow rate is quite low. When I had a pressure washer that had a flow rate like that, I found myself using the garden hose to wash down the decks and driveways, maybe I'm just more impatient then others. For tractors and stuff, its fine.

I too have the Mi-T-M belt driven unit - mine is 4.6 GPM with a 11 hp Briggs and it will definitely do the job. I bought mine used about 10 years ago for a song, don't know what they actually cost but I would definitely pay for a new one if I were looking to buy. Be forewarned though - you get a unit that does have the flow, be sure your water supply can keep up with it if on a well or spring, it will definitely go thru some water quick. The higher volume of water is what does the cleaning so good on larger jobs. Mine will cause my well to start pulling a little sediment if I run it much over 1/2 an hour or so - the only time my well does so.

Your telling me you can fill a 5 gallon bucket in between 12 and 30 seconds, with your hose? Is it a fire hose?

Someone will do the math, but I think it is going to take over 100 psi. to get that kind of flow out of a 1/2 in. hose.

Everywhere I have lived, 2.5 to 4.5 gpm at the outdoor faucet, has been the norm.

Oh geez, easy. I can easily fill up 3 - 5 gallon buckets in a minute. I use pretty much only 3/4" hoses around my house for irrigation, use garden valves instead of hose bibs. Our hydrants have a minimum of 600 GPM with the norm being 1500 GPM for all newer areas. I am not on a well anymore, but when I was, my output was limited to the pump which could do about 10 GPM and an unlimited supply. Folks in the area on wells that have less than 5 GPM typically install 1500 to 3000 gallon underground concrete tank(s) that the well pump keeps full with a smaller pump in the tank to pressurize the pressure tank.

Northern Tool's "Northstar" unit...6.5 HP Honda GX engine with 3 gal per min at 2500 psi has worked well for me without problems....as a home owner. I bought it thinking that it would help me wash cars/truck (I'm getting older now). But it is more trouble than it's worth for that. In fact, a hand wash does a better job, with less effort...we're not talking monster mud here.

However, doing concrete patios/driveways and wood decks in preparation for sealant, it is well worth the cost and effort. Mine has a General Pump direct drive, triplex pump, bought new eight years ago at about $800. The company support for a couple questions when new was very good. I store mine indoors during the winter. Be careful on wood etc. You can literally blow it apart. Using the right nozzle, pressure and some experience controls that.
Water source is important. Originally we had a rural 2 inch Main water supply with low pressure. But a new, 6 inch Main line has solved that.
Loaning any tool out, even to family is another whole thread. I'll do the chore but won't loan out.

I have a Landa pressure washer,it is 3000 psi and has a 310 degree furnace. I have a extra reel attachment besides the wand and reel that came with it . My extra reel has a non- abrasive hose and jetter tip .I can thaw frozen septic ,culvert lines in the winter and I jet out clogged septic ,sewer lines,distribution boxes the remainder of the year. I have to be more carefull around my tractor,I can blow of the decals with it. plowking

That is really an ideal setup for a modest price with great performance. I'll take 3 GPM and 2500 PSI over 2.0 GPM and 3000 PSI any day

Landa has great products. I also use mine as a jetter for sewer lines and culverts. I have struggled opening up a couple of 8" culverts but anything under that and it works remarkably well.

I bought a Karcher (Honda powered) unit from Costco about 4 years ago to take off loose paint on the garage before painting it. I have used it on my wood deck before painting also. No complaints at all about the unit. I drain it for the winters and add some fuel additive before storing it in the unheated detached garage for the winters.

Also, you can't beat Costco's return policy.

What ever you get, get one with the Honda engine. I have 4 pressure washers, with all Honda engine. 5, 8, 11, 13 HP. GPM's is good, and but they never run at the rated pressure. They only go into relief at that pressure, maybe. Also, the accessories is what makes cleaning easier. , such as a turbo nozzle, driveway rotary cleaner, a unit that will also blast sand as you pressure wash, sewer cleaner, 24 ft extend-a boom. I have done cool decks, docks, brick concrete, wood, fence, patio furniture, auto's, mobile homes, etc. The most difficult to clean is old oil that has been there a while. Detergent and bleach injector is good to have also. A pressure gage is useful but not necessary, and will show the pressure you are using with any tip. To use less pressure, throttle the engine down to the desired pressure. Never, never drink water from a pressure washer gun.

Honda engine, Cat pump. The rest is academic. I have the 13 HP Honda / Cat and after 15 years of use, it runs like a well-oiled Singer sewing machine.
