Hight Pressure Water Washer

[geoffphuket]

Cleaning the drive the other day, there was a loud pop and I was showered with water as the hose to my pressure washer ruptured. Is there anyway to repair these things or is a replacement necessary? With all the expertise out there, I'm sure someone's done it

[buddy]

More details please.

Was it a break at a fitting on the machine, the hose?

A photo would help.

Just a (very) small hole midway along the hose caused by abrasion - I think it was rubbing against the fence. Sorry no photo

Hi geoffphuket,

I need a repair or replacement also. The dog chewed my hose.

My unit is a Italian Aannovi Reverberi AR VIP.

Rebranded in Thailand as Zinsano BlueClean 610. 130 bar, 1900 psi.

These are hydraulic hoses.

Don't know if this small a hose ID can be spliced. I hope so.

Our "AirCon man" uses a smaller unit, and has long hoses.

He said they are expensive to have made,

I don't remember how much but seems it was 300~400 baht a meter.

The "Pest Exterminator" (Termite) people uses a cheap Chinese pump, and long hoses.

Far less pressure output there, likely no more than 30 bar.

So a cheaper hose is fine for them.

I know I will need a very good (expensive) hose if it cannot be spliced.

Wherever you live, go to the local hydraulic hose shop with your hose.

The good people in the "Farming in Thailand" forum can offer more help.

Hope this helps.

Hopefully there's a photo here

I would think that the hose you have on your machine is constructed of a woven textile braid opposed to having a wire braid.

It is not advisable to mess with high pressure hoses and carryout an "it'll do" kind of job.

Although your water pump will have a small flow, it is worth considering that 130 bar actually means about 130 kg per centimetre squared.

It will cut your skin and worst still, allow water to enter your blood stream.

You have several options but all will involve a trip to a supplier that deals with high pressure hose.

As howto says, take off the hose and find either a shop to buy another one or a hydraulic shop that will be able to cut, swage two new ends and join them together.

I would go for the second option as it may be cheaper, depending on the condition of the hose as if it appears to have some other damaged area you will be taking it back again soon.

Is the hose original?

Perhaps it is under rated for the pressure that the pump puts out.

I am in the process of planning the hydraulic hose connections of a Tunnel Boring Machine that will have a combined length of 4.5kilometres, from 2" (DN50) multi spiral braided 250 bar working pressure to single wire 3" ( DN63) as well as smaller 350 bar working pressure hoses.

Cheers

It's only a cheap Black and Decker model (PW1350) 120 Bar. Unfortunately the hose does not detach from the gun, so it would mean buying a complete replacement - which I suspect would be as much as buying a new washer

[soihok]

Well done , we have a photo now.

It is a textile braided hose and probably 1/4" i.d.

Not much choice Geoff, it will have to go to a shop for repair or renewal.

Any hydraulic supplier can sort you out with this, depending on what the ends are but most of the time suitable thread adapters can be provided to make the correct connection.

Geoff, if its only light you could take the whole thing down and ask for the damaged section to be cut out and two ends crimped on and connected together.

Agree,

I have done Heath Robinson repairs to hoses in the past to keep the job going, but they were always temporary until a spare replacement hose arrived.

Take it to a Hydraulic supplier/repair Shop, this partial abrasive puncture should be a doddle for them to repair.

Safety first.

Thanks for the advice guys :jap: . Now all I need to know is a shop on Phuket

Don't see anyway to detach the hose from the gun

Two Philips screws in the photo suggest that the gun itself can be disassembled, try disassembling the gun first to see if the hose can be detached.

TIP -

Make sure you take the washes and components out in order and lay them out in a line they came out in first second and so on, so that when you come to re-assemble it just reverse the order it came out in to make it simple.

Good luck.

[geoffphuket]

Tried that but it didn't work. I think it means dismantling the whole gun which I'm reluctant to do - being a Black & Decker it probably won't go back together again

Here's a simple solution.You will need a metal pipe with a smaller diameter than the hose.Cut the hose neatly and push the two ends over the pipe.Secure both ends with jubilee clips.Hey presto.

geoffphuket,

PLEASE do not follow "spud1" comment/advice,

while that will work on a (very) low pressure line,

It would be a very foolish and dangerous fix to a very high pressure line.

I've seen your pic, that is a lot of abrasion to that hose.

Please inspect the hose end-to-end and identify other areas.

After you have inspected that hose,

please estimate "the number of hours" you have used that

"cheap" Black and Decker model (PW1350).

Yes, the "gun handle" will come apart, and therein can be removed.

Well usually.

If not, the "shop" will perhaps have other "gun handles".

Choose one that meets the pressure requirement you need.

However if your unit has quite a few hours on it,

and in addition the hose is bad in several places,

perhaps you just need a new unit.

(I'm not fond of Black & Decker tools).

If you want a new unit, such as mine or whatever,

here is the distributors link

http://www.singsanguan.co.th/ and then

http://www.singsanguan.co.th/th/zinsano/zinsano.html.

There they have "home" units and "commercial" units.

They will ship to you.

BTW, it does take a unit capable of 100+ bar to really clean the scum off of a driveway, and those cheap china units will just not do the job at hand.

In my setup: I purchased

- a cheap luggage Carrier

- a cheap filter (very cheap insurance) and

- quick-click connectors for incoming water.

Mount the unit with those 'stretch cables" and the filter.

Very portable. It is a good setup.

Guess I need to take some pics and post them.

Anyway, perhaps the shop can swage-splice your hose together.

DO NOT attempt to do it yourself. Very Bad Idea.

And please listen to "buddy" and "soihok", they know what they are talking about.

Ignore me, I'm just a fool.

Cheers

Nah, no fool. Thanks for the advice

I'm a bit annoyed really because the cleaner has only been used 3 times previously, hence my reluctance to buy another new one, but I suppose it's probably my fault having draped the hose over several obstacles.

I've not done anything about repairing the hose yet as I can't think of a shop on Phuket to take it to........ANYONE???
