RO unit needed Suggestions?

Right Iv had enough of getting Ro water from the LFS its a pain carry 20 litres of the stuff filling it up storing it and so on.Usually im a no go to plumbing anything in as it usually ends up in wet floors but I was talking to Darren (platty252) about them and he was saying that you can just clip them on and off to your outside garden tap.
RO units are a very gray area for me and I have tried to read up on them but it says nothing about installing one.
What im basically looking for is a no frills no thrills one which I can clip onto my garden tap and I have RO water.
Any suggestions on a make of RO unit???

If you dont mind me butting in Padraig,I'm in the same boat as you,I have heard that you need to keep constant water pressure on the unit to prolong the membrane.Does anyone know if this is true,or can you,like Padraig says,just "plug it in" as and when you need it?My concern is the large amount of waste water,if this is,indeed the case.

I am using an Aqua medic easy line 90. I just put a T connection on the mains water and fitted an outside tap. This is inside the house because if you were to use the tap outside the membrane would get damaged in the cold weather. I think it's 4c or lower and it will damage the membrane.
I keep the RO unit connected all the time, but i only use it once a week for 8 hours.
This gives me all the RO i need and by keeping it connected with no water running through it the membrane stays wet with no damage.
If it was to be disconnected and left for a period of time the membrane will need to be removed and placed in a special solution to stop it getting dry or damaged.
The connections for connecting to an outside tap can be bought separately if they dont come with the RO unit.
Hope this helps.

I have an RO-MAN its very simple to hook up . Theres no cutting copper pipe for joints all connections on the system are push fitting. when hooking up to the mains its a clamp and just twist the the head till you get water. Its that easy. I got mine in Fish Antics but you can shop around. Hope this helps.

I have an MWS unit, came complete with tap connectors for an outside tap. Just screw it on, no messing around with any plumbing. I got it on ebay from France for 48€ incl. shipping. Under ideal conditions it should give me 380l/day. This would be 6 bar of pressure at 25 degrees. I have 3.3bar and the temperature is between 11-15 degrees. I get about 200l/day. More than enough for most people. I could go out and by a booster pump to get more water but I really don't requie it.
Here is their ebay store:

go for the auctions. The units go for about half of what they will cost you on 'buy it now'

is the pressure just required for the speed in which its filtered ie
Low pressure low amount of litres per hour etc
Or is the high pressure required to filter the water properly.
@acara no prob actually meant to ask that question to

you will need a minimum pressure of about 3bar so that the water can be forced through the pre-filters and the membrane. The higher the water pressure (anything over 6 bar will damage most RO units) the more RO water you will get in any given time. The optimum parameters (the most RO water in the shortest time) will be achieved if you run the unit at 6bar and 25 degrees water temp. This of course is unrealistic for most of us since our warm water taps wouldn't have that sort of pressure. My cold water tap pressure is barely over 3 bar :!: If you are not sure what your water pressure is get hold of a plumber. They have a little gadget that will screw on to your tap and tell you what pressure you have.
You will also have to invest into a TDS meter as well. Neither the filters nor the membrane will last forever and need replacement at some stage. The only way to find out if everything's still working OK is with a TDS meter. If your TDS goes up you will need replacemnt cartri´dges. The first thing that will genreally go is the activated carbin filter, the sediment filter is next and then the membrane. All can be changed easily and a monkey could do it.

TDS meters come in hand-held and in-line varieties. The hand-held one tend to be cheaper. The in-line are just more convinient. If you are like me and have a wife that has a compulsive cleaning disorder and moves your stuff around every couple of weeks, go for an in-line meter. I am forever and a day looking for my hand-held one

Already sent a pm to him cheers billydiscus

You will need a minimum amount of pressure to force the water through the membrane after that it is just the amount the unit will put out

Try www.osmotics.co.uk. Got mine from there. If i remember it was about 50 to 60 euro.
