Will a pressure washer thing work on a tap with a weak flow?

[HONK]

I am considering buying some kind of car washing backpack jet stream thing from the internet, it plugs into the tap or what not and is a pressure washing thingo.


My tap outside has a weak flow, as if the tap was only turned a quarter of the way.


Would that work with a pressure washer? I hear it uses less water than a normal hose, so...

Is it on Temu?

I don't know about backpacks, mine have always just had wheels.

Also not sure about using "less water"? The beam is concentrated, but it's very high pressure. Certainly I have discovered that if the flow is obstructed, eg the hose gets caught, the washer will "starve" and splutter.

These washers normally specify a pressure, and obviously the more expensive models can generate more pressure. So a smaller, lower pressure, unit, would require less water.

I'm on tank water and my pump is nowhere near the level of town water for pressure. My pressure washer works fine.

If water flow in is equal to or greater than waterflow out, you'll be fine.

Ha ha, I highly doubt my pressure washer is saving me any water at 10.5-liters per minute using a 4.5 orifice.





From a normal town water supply by the way. I did need a 15-amp plug though.

Some brands do.

Running one from a bucket would be the lowest pressure possible.

You still need a little gravity to get it to work hence putting the bucket higher than the pressure washer.

hi
Normal house mains pressure is 35-45 psi. Commercial upwards 65psi
Water flow is around 40ltr per minute for domestic house
flow is measured by how many litres in a 15 second duration . Then x 4 =Litres per minute.

For a pressure cleaner keep the supply hose [typical 1/2 inch ] short as possible
Most important use an inline water disc filter in the supply hose . The grit and occasional small pebble will damage the pressure cleaner . Warranty is also void if debris /damage is found internally .
