Can you use a pressure washer attachment on a regular water hose or is the high-pressure machine needed?
Question:My needs are modest. I simply want to do things like reach some high spots on my house to get rid of spider webs, or light dirt.
Answers:
By an attachment I assume you mean the WAND and SPRAY TIP for the end of the hose.
The distance the water travels and the force that it cleans with are directly related to the PRESSURE, as is the volume of water that discharged.
If you reduce the pressure to that of a Garden Hose Spigot on your house your reach is correspondingly reduced.
The bigger issue for you is that the Pressure Washer Wand does not have the same threaded connections as a Garden Hose, and some do not have common connections.
If you are not prepared to purchase even the lower pressure range household pressure washers, sold by people like Home Depot or Walmart for as little as $85.00, then you might want to try a Lower cost alternative to a Pressure Washer Wand first.
There are Garden Hose WATERING Wands, up to 48" long, with Female Garden Hose Thread on the inlet and Male GHT on the outlet.
You can also buy short SWEEPER nozzles with GHT that have a small diameter outlet that concentrate the flow and maintain the pressure in the line. This works like when you were a kid squezzing off the flow at the end of the hose with your thumb and the water shoots farther, or in simple terms restict the flow and the water pressure behind it increases (up to a point).
I have seen these in Garden Supply stores, Hardware Stores (seasonally) and Home Supply stores, like Lowes and Home Depot (seasonally).
Another nozzle that can restrict the flow even further is an Adjust-a-Power Nozzle, which is a short twist nozzle that has an interior rubber tube pinched by bearings to create a finer stream with the most hitting force and reach possible from the 100 PSI or less available from your household water supply.
Keep in mind that the smaller the nozzle orifice the smaller the flow rate, at a given pressure, and if it is the volume of water you are depending on to do the cleaning, you may take a while.
If you go the route of a traditional Pressure Washer Wand and tip, you will need to make sure you get an adapter (or a series of adapters) to convert to the thread needed for the inlet connection on the Pressure Washer Wand. That done you are again limited by the 100 PSI or less available from your household water supply.
Good Luck
You need the machine...
you'll probably need the water compressor to get any decent amount of pressure out of those things. If you can't do it with a regular hose sprayer, the pressure washer attachment won't do anything but constrict the flow. You can get a decent pressure washer for 75-100 bucks.
so long as the fittings are the same, you can, but it wont have the pressure of a pressure washer, and thus, you might as well be using a regular hose.
though, since the nozzle is smaller, and the stream tighter ad faster, it will have some increase in pressure over the standard hose with a "jet stream" attachment.
it dpeneds on the pressure of the hose, ti might just stall right there, but go ahead and try it, nobody's gonna get hurt
most citys water pressure is only about 30 LBS of pressure. that boost pump is needed to increase the pressure to a higher point, so the pressure can do it's cleaning.
I just tried looking for the same thing over the weekend. There are some they sell that will help get your spider webs down and even wash stubborn dirt off of your car/wheels. But for the full effect of the pressure washer as in getting old paint off the side of a house or fence etc then you need the real deal. Most washer run about $200.00. You might be able to find one to rent at your local hardware store.
I would say you must have the pressure machine to get compression to have high pressure capability. Putting a pressure attachment on a garden hose will simply occlude the water flow from the hose.
You can get a very small Karcher pressure washer. I have shown links to this below. Some are as low as 1500 PSI and under $100.
Once you have one you will want to use it for everything though. Washing the car, driveway, house, sidewalk, wood fencing. I have the 1750 PSI mofdel, and it works great. You can get one of these at Lowe's and possibly even Wal Mart or Home Depot.
Again, see the links, and the Karcher website, has lots of details on how to use them for many applications.
