I really don't have the space for a Homebase 1000 litre RO system, so I would like to have an all in vehicle setup. I was thinking 250l was enough since I'm domestic and having not too many customers a day. Should I stick with 250l or get a 400l one? It's for a Citroen Berlingo, I think max payload is 600kg.

At this moment everything is traditional, but late 2007 or early 2008, I'd like to switch to wfp. I'm researching as much as I can, and I must say it is all a bit difficult searching for the info I need. Especially on hose fittings etc.

If anyone has a schematic (can be simple MS Paint) of how everything is connected to each other in the van (with the appropriate name of the connectors as well), that'd be great.

Bit of a multipurpose topic this, but oh well! Better then to start another one I guess!

thanks!

Its all very simple really.

Thanks for the explanation, helps alot! Just a couple of questions more.

- (Tank size 250l or 400l)

- What kind of Connectors do you use from the Tap to RO system?
- Where does the hose from the RO system go? In the top of the tank? Or with a proper barb screwed in the tank, and    at what height?

- What kind of connectors do you use with Microbore? And is 'Pump to Hosereel', and 'hosereel to pole' the only   parts in the system that you use microbore?

- How can you stop it from overfilling overnight? (and flooding the van lol) do I need a Auto shut off system for that? And would a floater based one be enough?

Looks doable for DIY installation to be honest, don't need to spend £2500 for a complete system hehe.

Tank:  250 really. 400 will weigh around 430 when full. That only leaves you 170 for all the other gear, fuel, people on board. If only one person is in the vehicle you should be just about OK with the 400 but 2 will definately put you overweight.

The RO system suppliers all do tap connectors for the 1/4 inch piping they use for the type of system that you will need. You can put the pipe from the RO?DI system into the tank lid but you risk flooding. You can get a cheap,..25 quid..ish auto cut off kit. You would need to drill a small hole in the top of the tank to fit it. Its basically a very small float valve.

The tanks come with threaded female outlets but all the suppliers do connectors for these. From the tank to pump and pump to reel its easiest to use 13mm hose with just a hozelock connector to the reel. You are best to buy complete microbore kits from the suppliers with the reel and microbore hose. You probably could save a few pennies by finding your own connectors but it wont be worth the bother.

You will be able to get a good package deal with all the bits and bobs you need for around a grand or a bit less. The size of the RO and type and length of pole will be what makes most difference.

Thank you so much for that info!! I really appreciate it! (250l it is!)

I have another question (hope you don't mind)

How do you adjust the flow rate? Is it enough to just use a Pole control valve? And how do you know how much pressure you need? (and how to adjust the pump accordingly) I hope the question makes sense. My pump would be a Flojet 60psi pump.

Thanks again! 

[Extremeclean]

Through experience I now always use a Varistream to control flow. You can use an inline tap to do it but you risk burning your pressure switch out. The Varistream gives you the right pressure for the flow you want automatically.

[[GQC] Tim]

Sounds great! What should the pressure be for a 1 pole operator? (100meter hosereel) And why would you ever want to turn the flow down or up?

Am I correct in saying the following lists the most expensive and main items I need? Did I miss anything? (other then connectors and hooking up pump)

RO Man 75 Gpd Pro4 Stage RO System with DI unit     
Inline  Dual TDS Meter                
Flojet 60psi Pump                  
VariStream 2                     
Tank 250ltr                     
19 Facelift Glass Fibre Pole               
               
25cm Vikan Jetted Brush Or Tucker Brush                  
100 Meter Micro bore Hose               
10 mtrs Micro bore hose (Reel to Pole)         
Hose Reel                     
Auto shut off system (float based)

Heavy Duty Tank Fitting Kit            

Speedlining van

Go for a 400l , trust me I have a 250l which is not enough and I have to fill it up
each day at customers houses which can be a pain.. I am now buying another 250l tank to give me 500l capacity which will be enough.

hi how long dos it take to fill up a 250 tank with di filter ? do u hav to leave it over night?

[DASERVICES]

 With a DI system a 250L tank is filled in around 10mins.

[007 or what]

You say that you dont have room for a 1000ltr at home so why not start with a 650 ltr upright at home. I started off with a 650 at home but with a 250 in the van, when i got busier i put the 650 in the van and sold the 250 just something to think about

[cleaning co]

hi doug how well do these di systems work as i live in very hard water area

[DASERVICES]

Your resin would not last long so your costs will be high, therefore for hard water area you will need an R/O which will be a longer proccess.

Hard water area = RO + DI only, just DI is way to expensive for that. Check out the link below and you'll have a rough estimate.

Well, I'm moving in 2008 to a 1 bedroom flat. Maybe I'll have a shared garden, but I don't see that working to begin with. In fact even a vehicle based setup might be problematic.

I've just upgraded from 250 to 400 litres and i can work all day now. I used to come home luchtime to refill with 250 litres.

[[GQC] Tim]

Thanks for that, I guess 400l is a must then! 

If anyone could answer this last question, that'd be great!

What should the pressure be for a 1 pole operator? (100meter hosereel) And why would you ever want to turn the flow down or up?

GQC, to answer your last question, pressure is not important, a 60psi pump will supply the same flow as a 100psi pump if the flow rate of the 2 is the same.  It is flow rate which is important - I'd recommend a 5ltr/min 100psi shurflo pump from williamson pumps (www.williamsonpumps.co.uk), one of the best but cheapest pump on the market.

Just looking through this thread again I reckon that a 400 litre tank in a vehicle with a 600kg payload is just not on.  Even a 250 could be pushing your luck.

[JM123]

we fit a 400ltr tank as STANDARD to all 600kg payload vans.  a 400ltr tank hold less than 400ltrs (about 360 due to baffles), tank weighs 27kg, plus battery and 2 poles plus reel etc comes in at around 440kgs so assuming a full diesel tank (45kg) you'd need to be over 17stone to even come close to your payload, and thats fully loaded with a full water tank and fuel tank.
