Pressure Washers, taps, and hosepipes

[Nanako]

You place the supply input hose into a tank of your choosing. eg a bucket of water.

As I said it's suitability depends on why you want one. If you don't know what your usage will be thern that it suggests you don't actually need one.

i had thought of that, but then wouldnt i need some kind of seperate pump to send it up that hose as well? What kind would i need to supply enough water for a pressure cleaner

I do know what my usage will be, exterior cleaning. I will be using this cleaner a couple times a year to blast clean the area around my porch and garden paths. I may find other purposes for it besides, but thats the main goal

No, it's low pressure that's the problem, not high. You can, and should, fit a device on the pipework.

i don't understand.

The scenario i'm thinking is, if the tap is running, and the hose is filling the pressure washer, but then i leave it unattended for a few minutes, it might overfill and the water would have nowhere to go but back down the tap, isnt that the bad situation?

Modifying the pipework is absolutely off the table. I'm strictly thinking in the realms of working with what comes out of the taps as is

isnt that the bad situation?

No. Water can feed back into the mains if the pressure drops/is low for whatever reason. Low pressure in the mains could "suck" water from a property and if that water is contaminated then it could be dangerous. Hence, check valves are used so that water cannot back feed into the mains.

Modifying the pipework is absolutely off the table.

Then, unless you ignore the rules/law, you are stuffed unfortunately.

Unless you want to purchase a bowser then you're asking for something that doesn't exist!

I have a friend who lives in 2nd floor flat... He wanted a way to wash his van from his kitchen tap... I simply installed a connection to the kitchen tap cold feed under the sink that had a lever valve, check valve and cap that enabled him to connect his hose there and feed it out of the window.

it doesnt exist? Why not? I can easily imagine how one might be made, you'd just need a little rubber aperture that stays closed until sufficient internal pressure blows it open, like the caps on sport drink bottles. Or hell, something similar to a hamster drinking bottle in reverse could work too. i can imagine a ton of devices that would release fluid when the internal pressure passes a certain point, i'm sure such a thing must exist

I looked up a bowser, that seems to be a huge trailer style water tank? Definitely excessive for my needs. Do they come in tiny versions, like 5 litres ?

i can imagine

We can all do that!

When you find it, can you ask if they have money trees and send me a link please, to...

You keep saying that but not why!

Does it matter why ? Surely the statement that i'm not going to modify pipes, should be enough for folk to stop suggesting i modify pipes, so we can confine the mental workspace to the productive land of hoses, buckets and external pumps instead

But if you must know:
1. Its outside the scope of what im trying to do, too much complexity
2. I don't know the first thing about pipe plumbing, which means i lack the skills to cope with an emergency if it goes wrong
3. My landlord would not be happy with it, whether or not modifications are done successfully
4. The pipework is a complex system necessary for the house to function correctly, and like any complex system it must be handledd with care and expertise that i lack, or the chance for an emergency is high
5. Pipework, like electrics, is a system that is dangerous when it does go wrong. i probably wouldn't die, but flooding would cause damage to the house

is that enough? It feels like enough. I'm not a plumber, at this point in time i do not want to become a plumber

i just want to use a pressure washer without poisoning the local water table

 

[Nanako]

based on a bit of logic, and some of the helpful replies, it seems like the solution i need is to
1. Place a bucket under the tap
2. Place a submersible pump inside that bucket
3. Attach the hose to that pump

Then if anything overflows it just goes down the normal drain system, no possibility of backflow, problems solved

can anyone advise on purchasing a little pump to accomplish this ?

Jeez... So combative!
Anyway...
A Plumbing and Heating forum is for... Guess what... Plumbing!

Try Temu or JML

Just put the hose to the pressure washer in the bucket. No pump required.

You can buy kits of all the parts needed, to add an outside tap, with a minimum of experience needed to install. You just clamp them around a suitable cold water pipe, tighten them up, they puncture the pipe, and connect. You don't have to fit the tap outdoors, you can fit it anywhere which suits.
