thanks for any help.

no problem - if you live in an area where the tds (total dissolved solids) levels in the tap water are above you would be better off investing in an RO/DI system - here's how it works.
Tap water passes through a sediment filter (to remove the larger bits in the water), the water then passes through a carbon block to remove chlorine. Next the water is passed through an RO membrane (Reverse Osmosis) which removes the vast majority of dissolved solids in the water (mainly salts), there are 2 pipes from the membrane, one for product, the other for waste as the membrane cleans itself by flushing water over the membrane to clear any debris etc. This waste water goes to drain. Finally the pure water passes through deionising resin to remove the last of the impurities. If you live somewhere where the water tds levels are less than 100 you can get away with just a di system.
Simple.
Ahhhhh, can let the hand rest.....................

oh yeah and you'll normally waste about 4 litres per 1 litre o the good stuff

wightsurf,
Have a look at this site:
http://d.co.uk/
It's created by a member of this site (Matt) and it is the best I've seen for a full explanation of what you need, and how it works to get started.
I thought the site was so good I donated a tenner, which Matt spent on pizza.
So have a look quick, before the site goes into liquidation.

you guys crack me up. :D

Mmm, wouldn't agree, at worst the waste to pure ratio is 3:1, at best it can be 1:1
With the system that a certain Roy Harding has, his waste to pure ratio is 1:1 and his R/O is bringing his TDS reading down to something in the area of 0.001ppm.
A very effective and efficient setup.
If you are on a meter it will increase your bills of course, but by how much will of course depend on how much water you use in a day.
The daily cost of this is very low however.
As Tosh said, Matt's DIY site is a great place to start, lots of very good info.
Another one with many FAQ's and information is:

JM123: What a clear and precise account of the ro system workings,easily understood by a novice[which Im not] but a few "pro" wfp users wouldnt be able to
explaiin it so well,it works cus it works mentallity.
a cracking write up
