The most basic of DIY system needs only a tank, a pump, a resin cannister - with resin - hose pipe, connectors and a pole.
To build it it goes: water tank - pump ( connected to a 12v battery ) - resin cannister - hosepipe - pole.
It'll work every bit as well as a factory built £10k system for a fraction of the cost.
We source our components from Varitech in Bovey Tracy, Devon but I'm sure you'll have a more local supplier.
At the end of the day you are just trying to produce pure water; no more, no less. If you want a mega money outfit that's fine; if you want a system that works for a fraction of the price DIY it
