also what do I go for a D I system or R O system - which do you guys use and why?
Im still trying to get grips with all this lot so bear with me lol
Here are the facts, unless you are one of the lucky ones who live in a very soft water area such as the South West or the highlands of Scotland you will probably need both a D I & an R O.
An Ro will bring your TDS reading down to a reasonable figure but you then need a DI Cannister filled with Resin to polish off the water to get it to around zero.
R O Machines are designed to run with very little need for regular service( apart from changing the filters every 3 - 6 months), ie they don't require anything to be added to them, whereas a DI Cannister needs its Resin replacing on a regular basis. If your TDS was say an average of 250 & you just used a D I system you would need to get through so much Resin that it would cost you a fortune.
So most guys on here would use a combination of both, thats what I do & I haven't had to change my resin for about 4 months now.
The other basic thing you need to consider is how you want your system setting up, there are quite a few different options & lots of different opinions as to which way is best. To keep it simple you can have a garage based system where all your purification takes place in a garage or outbuilding, the water is stored in an IBC Tank & then pumped into a tank in the van each day or you can go for a van based system where all your purification actually takes place inside the van, so you fill your tank up with tap water & then it cleans it as it goes along. There are also combinations of both systems as well.
If all this sounds terribly confusing give me a ring & I will try to talk you through it. (Mob 07977 517914)
By the way the guy who is selling the system on Ebay is taking an awful risk installing IBC tanks inside vehicles. You really should use a baffled tank to stop the water sloshing around, plus most vehicles we use do not have a 1000kg payload anyway.
