Thread: Domestic Mobile H2O Transfer Unit

Hi

Some of you may have already seen this thread on the Renovation (sister) site already. However given that not everyone using (reading & posting) this metalwork section frequents that site I thought I would post it here to. Especially given that most of the build will use metal. So if after reading my statement below you feel that you have something positive to add then it would be much appreciated.

Btw, this is the link to the thread in question.

Hi,

I am contemplating on making up my own mobile H2O Transfer Unit. As you will see from the image below that there are units out there that do this sort of thing. However, I will want one that will transfer with a large force i.e. washing a car, so it needs to be at least the same at domestic water pressure or preferably greater.

One item I just saw on EBay was a Kerrimuir electric pump with a cover but this may not be required if I put the unit in a sealed are on my machine. Then what about if there is no electrical supply? Well given that I only intend to use it for domestic use that shouldn’t be a problem but then you could use a petrol operated one. Or when that becomes $8 a litre we could use solar panels but then I think that is a long way off yet – well I am hoping so.

Has anyone done something along these lines? If so, would there be anything you would change given the benefit of hindsight? Would it make any difference having the pump above the supply of water or vice versa?

I would appreciate your thoughts or suggestions in how I should tackle this.

Regards

MH, couple of questions...

Are you planning to cart the water as well, or just the pump on its own?

Are you wanting to tow it, or just move it round the yard?

How far do you need to move it?


Just for interest, I have three 5000lt water tanks on my 1/4 acre property. I have an automatic pump that retails for under $400.00 that gives me mains pressure. And I also have a Gerni. There's not alot I can't water, wash, or clean.

The thing to check with most water pumps is whether they need priming. Our CFA trucks can move a shipload of water, but don't like pumping air.

Hi Yonnee,

Thank you for your interest.

I am thinking of moving both together as a unit - that way I can move it around both the back and front yards. However, what I have learnt from my trips to a few shops and talking to there staff, is to put the water supply above the unit to allow atmospheric pressure to help with the flow.

Are you wanting to tow it, or just move it round the yard?

As mentioned above I presently only plan on using around my yards. However, I don't plan on it being that BIG but it's not to say if someone in the family wants to borrow it they could throw it in a trailer.

How far do you need to move it?

I apologize but I don't quite understand the question. I think the above answers will give you some idea.

I am going to give Karcher a call this arvo to see if the Gerni I have of theirs requires domestic water pressure to operate or will I need to buy a certain pump that will give out enough pressure for it to operate? Does your require a pump to work? Btw, does anyone know what is roughly the pressure that comes out of the mains?
