I have a caravan in storage, there isn't any water in the storage area but there is water on the adjacent campsite. It's a hassle to take the van down to the water as the campsite warden doesn't allow you to use a hose.
My question is would this work ? I have a 40ltr Aquaroll (round drum that is used for fresh water on site) connect the Aquaroll via a hose to a power washer ( only using power washer to rinse the van) , power washer connected to an inverter supplying 240 v , will the power washer draw the water from the Aquaroll ? Do it now ! Your a long time dead !!

There is no reason why not as long as it can pull air into the barrel.

The barrel isn't air tight, I wasn't sure if the power washer needed to be connected to a tap . I haven't boyght the inverter yet as it's pretty steep cash wise. Don't want to buy it and this idea doesn't work. Do it now ! Your a long time dead !!

It depends on the washer, I think. Some are designed to be used in this way, others not. The latter may well not work.

I think Karchers advertise that they can be run from a waterbutt - so you are using a small waterbutt

It's a Karcher I have Do it now ! Your a long time dead !!

Don't think you'll have any problems with the water supply. It's the inverter you should check carefully to make sure it is up to supplying the power that the washer needs.

I'm looking at this one http://www.halfords.com/motoring-travel/to...ack-rpp265 Do it now ! Your a long time dead !!

After the last hose pipe ban we had, I actually measured how much water I used when using the pressure washer, I was surprised, at the time an ex member washed his with buckets of water and used about twelve buckets, with a propper water meter in the supply line I used 25 litres, a lot less that come one who used a bucket to wash with.

Showroom Shine works well  p****d off with a Digital Keyboard Warrior

Hi AD , I use showroom shine during the summer , but the van just now is filthy, I like to give it a good hand wash in the spring.
When I washed it on site last spring I used at least 12 buckets, like you say I'm pretty sure the power wash will use a lot less water. Do it now ! Your a long time dead !!

I would check to see if the washer can be powered from an inverter, the motor is a cap start type, with the voltage waveform from an inverter it may well screw the capacitor up.

How would I find that out taz ? Do it now ! Your a long time dead !!

I will see what I can find, here's some good info

It's modified sine wave, the motor will run noisy and hot, the capacitor may well be destroyed, Karcher washers are prone to failing caps, usually because they have been used on extension leads that have not been in wound properly, this acts as an inductor and causes havoc electrically.
This is from the Ring manual for that device.

Would this for if it's only to rinse?
