I have a new van coming in March. At the mo I have a purefreedom isothermal 650 litre 40/40 RO system in my present van, I would rather sell this van with the complete system in it. I really can't decide whether to go with a Van mount RO system again or change to a static system in my garage then have a 650-750 delivery unit in my new van, the delivery unit wouldn't even need a pump or controller as I use backpacks, which are filled using a tap valve from the tank outlet.
Could I get some feedback please, pros and cons of a static system, thanks in advance.

Static

Less chance of r.o's freezing at night
If you run out of water you can nip back and fill up
Less crap in your van
Less things to leak in your van
Less weight in the van

All i can be bothered to think of

Each system has its own merits and people choose them to suit there own requirements, for me I a multiple vans so I need a static system, it also gives me more room in the van for other equipment.

A few years back I brought a van with a system built it, that worked well, bit of a pain when changing filters and of course you have to fill up in the evening and turn it off late at night.

And before that when I had a slow RO system I usec a static so it could fill all day and evening so I could just transfer at will.

i use a system built in van, reason is i have no garage or space for a static, else i would

[brianbarber]

As said
If you have a garage or storage space, go static,
I prefer this as also it means my vans not tied up for the evening if I want to go out
  Had RO in van, I now defo prefer the static system.

As already been said , static
no mess, no fuss, no added weight, no need for frost protection

Thanks chaps, think I am gonna go with a static system in my garage, I will put an immersion heater in the IBC to heat the water then use a submersible pump to get the water into the van tank, doing it this way I will be able to get a bigger tank in the van as well as I wont have any pumps, batteries, filters or DI vessel which all add to the weight. For anyone that uses submersible pumps how long would it take to fill a 750 litre tank? and I take it that it would make sense to have a back up pump just in case?

I would always go static unless it was seriously impractical.  Using a submersible pump with 1 and a half inch hose, 750 litres should fill within a few minutes. I would suggest a re-think about using a backpack.  A reel, pump and leisure battery could be comfortably accommodated weightwise if you leave the water level down.  You would still have enough for a day's work.

Thanks for the info on the pump. I have been WFP for 4 years now and prefer using backpacks, there are 3 of us working out the 1 van, at the moment two of us use WFP's the other does a bit of trad on patio doors, front doors etc, if I can carry some more water the 3rd man will be able to do WFP when required.

OK gotcha.  I didn't realise there was more than one working from the tank.  I suppose the clue was "bacpacks (plural) - which I missed .  I know the water seems to go further when using a backpack.  Also, you're having to accomodate the weight of three people in the van's payload.  I see where you're coming from now.

No probs, you weren't to know there were 3 of us. After reading back the replies, as Don Kee has suggested one of the benefits of a static system is I could easily nip back home and fill up as I work close to home anyway.

It depends what you want, if you intend to have more than one van on the road then static would be best
If you work on your own then a van mount would be better.
You don't need to pump water from one tank to another.
You don't need an extra tank.
You don't need to take up extra space with another tank.
The R.O. and D.I. don't take up much space in the van six inches at the most, to be honest not even that.
Like I have said it depends on what you want.

Van mount all the way for me...

I like the fact that if your running low on water you can top up at custys houses...
