    Hello friends,

    I was just wondering if fitting an extra long hose to my pressure washer would cause any problems?

    The current hose is only 3-4 metres long, I’d like to fit a 10 - 15 metre long hose.

    I would like to mount the pressure washer in the external cupboard at the front of my house. So I can just open it and pull the lance out and wash the cars.

    Will this cause any issues, and could leaving the pressure washer in an un-insulated cupboard cause issues?

    Cheers
    Abs

    I assume you mean the hose from the tap to the pressure washer?

    I use a hose which is about 20 meters long to the washer as our driveway is at the back of the house and never had an issue.

    No, the hose would be short. It would be hose from the pressure washer to the lance. So the pressure washer machine can remain fixed in cupboard, and I simply pull out the lance.

    Sorry if that wasn’t clear.

    Not really, it may just make operation a bit laggy as the rate of pressure drop will be different in the longer hose, this is what most washers look for.

    However, you need to be careful leaving it outside in the cold, make sure all the water is drained or it'll risk cracking the pump.

    Can you buy a hose to fit your washer that’s as long as that?

    Long hose should not make a difference ( assuming you mean the water feed to the P/W ) if you mean the pressure feed am not sure but suspect not much reduction in pressure at spray head.
    Leaving it in an unheated exterior cupboard would run the risk on any water remaining in the pump could freeze and damage the pump, this happened to my Karcher when left in garden shed . Mind you I then bought a Nilfisk, which I prefer , but keep it in heated storage now.

    It'll make no difference. Longer high pressure hose is very handy. As said, it might change the operation of the start/stop slightly, but it'll be fine.

    And while not recommended, I left a little karcher washer out in the rain/wind/snow for years, completely uncovered and also ran it on hot water which is also not recommended, but it lasted a few years before someone stole it.

    The pressure loss should be virtually unnoticeable, we used to hire diesel pressure washers for working on cooling towers and hire additional hose to virtually double the length to around 30 odd meters, never an issue in pressure loss.

    I popped down Pirtek and asked them to make up some longer hose with quick release couplings for work, no problems at all.

    To describe the set up i've ran some copper pipe all with quick release couplings at the end to various points so they can unplug and plug in where they need to without hose trailing everywhere.

    The Big Karcher itself is connected to the pipework with a shorter hose again to a quick release so it can be disconnected easily for maintenance.

    A really long garden hose won't have an impact on your pressure washer OP. I use a Karcher at the front of the house but run a hose down the side so it's a good 30ft+ and no issues at all. :)

    Yeh? All the time!

    I make sure the lance isn’t too near the paint too, but I doubt my pressure washer is strong enough to damage it anyway.

    In winter yes , but take care to keep the pressure down, not the max available

    Yes, like everyone does, including detailers. It doesn’t damage the paint.

    My washer is a petrol one and produces over 200 bar/3000psi, and with a 15 degree nozzle I can get an inch away with zero paint damage.

    It’s a myth.

    I wouldn’t go near it with the zero tip mind you!
