Clean It Up

I'm moving my setup to a lockup.
Previously, my water supply to my RO was on a timer. If I got it wrong, there was no problem; a bit of overflow into the garden, nothing more. Now it'll spoil the day of the guy in the next lockup.
I need to be able to control the flow. I'm assuming some kind of ball-valve in my IBC stopping off my inlet to the RO, but I'm a bit stuck as to the exact solution, as there seems to be too much choice. Searching through past posts on here has just confused me more.
Does anyone have a nice, simple solution to this? Links to products you use would be extremely helpful.
Thanks,
Vin

I should add that my RO is a 4040, so 1/4" fittings probably won't cut the mustard.

Hi
You need to fit an overflow with hose to outside, preferably at the back where it won't be seen and into the drain the garage roofs should have. You could still use your manual timer as before.
Presume that you don't have electricity, so I would probably consider a 12v solonoid valve (normally off) with micro on/off switch powered by separate leisure battery that you can take away and charge at home.
If you have electricity, then a 230v solenoid valve would be better.
At one time some supplier used to supply a special ball cock valve that had an inlet and outlet so the inlet water would be switched off without contaminating your purified water, but I cannot remember who it was. I am sure that the long established WFP suppliers would be able to recommend a solution. If you use an IBC tank then you will need a piece of rigid plastic 'plate' to reinforce the valve area for it to work properly as the IBC tank plastic is very thin and flexible.
If you don't have electricity then you need to consider a different heat source to prevent your RO from freezing in the winter.

Give Varitech a ring. This is what you need on page 36: http://www.varitechcatalogue.com/
15mm 12 volt solenoid and the float. You'll also need a 12 volt transformer (like for kids toys) , some electrical flex and connectors. You could do it 240 volt if you want though it's not advisable. And some diy skills.
Varitech's where I got mine. Speak to them on the phone. They are helpful, just not particularly cheap. Can't see any on ebay at the moment though.

Thanks, Traps, that looks like a good solution.
Thanks to your suggestion, I took a look around and found http://www.virtualvillage.co.uk/1-2-12v-electric-solenoid-valve-for-water-fluids-001540-024.html?utm_source=googlebase&utm_medium=shcomp - it makes me feel like someone's taking the mick with prices like £74!.
But the main thing is that I now have a potential solution, so thanks again!

No problem. Haven't seen one like that before but then I'm no expert. They did used to have cheap ones on ebay but not as cheap as that one you've found.
I've uploaded some pics of my static when it was fresh and pre automatic water softener added in case that helps.

can this be used on a 12v system

Not cheap Vin, but this is what I have.
Great bit of kit.

This is what I would have recommended and is the option that I have for my 4040 RO despite the fact that I do not have a booster pump. Means that the RO can simply be left to its own devices apart from flushing.
