How to use a Karcher Pressure Washer with a Bucket

Published By -

If you don’t have an outside tap, or a hose pipe then you may wish to use a bucket of water to drawer water into your pressure washer. Using water from a bucket, water butt, a tank or barrel will save the amount of water you use.

Using the Suction Hose

With the upper models of the Karcher pressure washer range there is the feature to use a suction hose. This allows you to drawer water from a source such as a bucket or water butt, and below we shall tell you how.

Using Pressure Washer Suction Hose with a Bucket

To draw water from a bucket or barrel you will want to use the Karcher suction tube, this is a plastic pipe that has a screw fitment on one end that attached to your pressure washer. The other end has a filter and can be dropped into the water be it a bucket, pond, barrel etc.

Once dropped in you are ready to go. The filter on the suction tube will help prevent grit and stones from being drawn into and used by the pressure washer.

How to use a Karcher Pressure Washer with a Water Butt

The video below shows how easy it is to use a water butt with your pressure washer. You can either attached your hose to the water butt tap instead of a outdoor mains tap and way you go. The other way you can do this is by using the suction tube. Screw the one end to the suction tube input on your pressure washer, and then drop the other end of the tube that has the filer on it into the water butt and sink it to the bottom.

The filter on the tube will help prevent grit and dirt from being sucked up and passed through your pressure washer helping prevent any damage.

If you don’t have a suction hose you can buy the Karcher 5m Suction Hose and Filter for Pressure Washer Accessory. It is 5 metres in length making it easy to reach and extend to your water butt, with a solid screw fitment on one end and a clever filter on the other which is a single way valve. This is compatible with the Kärcher K3-K7 series pressure washers.

        Would a small, cheap, 12v water pump from eBay feeding the Karcher K2 work?
        I use a similar setup on my boat with success.

    I recently bought a G4.10 petrol power washer for cleaning my motocross bike. What’s the best set up to draw water from a 275L barrel in my van????

  2. Neil

    Cannot offer you positive advice, sorry. I have experienced the same problem. I even tried “priming” the suction hose by filling it with water and trying to stop both ends with my finger tips while I connected it to the Karcher. Still would not draw water in.
    Repeated failures and had to give up; had to use a mains tap.

  3. Sujamak

    Does my Karcher K4 Basic have the suction function as you show. Tell me how to do it.
    I’ve been trying so hard but always failed.
    Sorry for my broken English

    A rechargeable battery powered version would be ideal when you need to clean areas well away from a house or mains supply.

  5. Malcolm Bunn

    I have got a K4 eco workers perfect with a hose but not with the suction hose.and need this to clean the slabs around the pool please help.

  6. Delvon

    I just bought the K5 premium 2000 psi with the suction hose and it is only spraying a very small amount how can I fix this

  7. Pat Canderton

    I have a garden but do not have an outside tap and cannot reach the kitchen taps but I would like to get a pressure washer that works with out a hose pipe attached to the water faucet can you advise on the Best Buy if there is such a thing please

  8. James McLachlan

    Hi can someone help me please. I have a T350 T racer attachment that’s not getting to full pressure I’ve changed nozzles & still no better. The lance pressure is normal. Any ideas ?

  9. Daunter

    I use a k4, it takes a while before drawing water from my tank. I often have to connect it to a mains tap first to bleed out all the air trapped in the machine. It works pretty well once it begins drawing. I like the pressure, but after using it a few times, I have a tough time changing between the dirt blaster, vario and foam Lance. There’s just so much friction that the yellow bushes tend to stick inside the trigger gun when I pull out each accessory and because of this, I’m always fighting the leaks

  10. Bob

    My K7 Premium pulsates and has weak pressure when using a bucket. I primed the hose and ensured there was no air in the hose.
    Is this normal.
    Does the water supply need to be higher than the pressure washer?

  11. gw

    The K2 Basic I have just bought from screwfix has no way of delivering detergent through the lance
    the detergent bottle will only screw into the short tube there fore water pressure at this short range would cause
    the user to get covered in detergent immediatly there is No Tube /suction attachment at the rear of the unit
    should there be one? If not the product description is poor and misleading and I will return the unit to the store asap

    I imagine you position the bucket above and connect the hose, fill it somehow with the water so that the gravity does the suction. Alternatively suck on the hose from the bucket first and attach it when it drips around with the bucket not too higher, then hang it higher.
