Pressure washer flattens hose

[Bluecube]

It doesn’t look too bad. Can’t see it being a problem. However, it could be that your new pressure washer uses more water than the old one and the water supply can’t keep up.

As I said previously, if it’s going to be an issue then use a bucket and draw the water into the pressure washer.

I had the same hose flattening issue with my old Karcher. Maybe that's why the Karcher broke, perhaps not enough water going through the machine. But there was a time when I had no problem at the front of the house, so it surely must be this hose that's the problem.

I think I read somewhere that there wouldn't be enough power to suck up water from a bucket and that the water needs to be mains supplied. But I'd need a huge bucket anyway as so much water gets used.

I would say that the 25m of hose is just poor quality, shouldn't be collapsing.

Bin it and buy a hoselock one or something from homebase or b and q, if it happens again take it straight back for return and try different one

Let's see how I get on with this one. I did a squeeze test in the shop and It feels as solid and hard to squeeze as as the best Ultraflex Hozelock. Also, it'll be nice to be able to wind the hose up without it tangling and kinking everywhere.

Regardless of Hose the water supply is not enough otherwise it wouldn’t collapse. Shorting hose is effectively increasing the water supply. There are other options and variables which is probably why some people have no issues with 50m of hose.

Try turning the electric off and pressing the trigger to flow water through the pressure washer to make sure there’s no air in there, when I do this I often hear some gargling for a few seconds.

You'd have the hose on and the going into the bucket. A moot point anyway if the machine can't suck the water out.

Thanks everyone for your help and suggestions. All working properly now! New hose sorted it. I've binned the other piece of crap. I'm getting full pressure out of 25m and it isn't even unwound from the reel.

So, this cookie..

Not sure unreeling it will affect flow rate.

its fluid dynamics man ... straight through exhausts etc..
.... not unlike people leaving their (electrical) extension lead wound on a reel, but, ok, that's self-induction

... uncoiled ....

Fair enough. I just thought that coiled up might make it a little harder work or slower for the water to get through rather than a straight run through a fully uncoiled hose, but clearly it doesn't make any difference. I'm happy now, don't need to call a plumber and this hose seems pretty sturdy and durable and should last a long time, and at half the cost of a Hozelock. By comparison, the old hose was too easy to squeeze, not much firmer than a drinking straw. There was a moment today when it lost pressure which worried me but then I realised someone upstairs was using a washing machine at the same time.

With hindsight, I suspect I broke my Karcher last year because of that old hose not pumping enough water through.

Wow I feel sorry for someone moving a washer upstairs. You have got me thinking now though,y when I use my pressure washer it's not constant it seems to drop off but I haven't uncoiled it. I wonder if mine is closing up to, I just haven't noticed it.

I think I'd even get a cheap pressure meter / manometer - no ?... boiler in current house doesn't have one - thought it did.

it's not constant it seems to drop

if it's ageing - investigate sticky pressure relief valve, that fixed my karcher and was surprsingly accessible - it just bleeds water back through to input when hand off the trigger, but it may start doing that even when it's not
