Guys just wanted to say a bit of thanks for your help. I have been having a look at new vans and seems i can get a new vivaro for around £230pm but at the min im spending ALOT on petrol, so hopefully the saving from switching from petrol to diesel will offset a bit of the cost. As well as the lower running costs for repairs etc atm.
Should be having a look at vans next week and go from there. So the next step is the kit to buy. I will be switching from trad to wtf so need to buy everything. Reels, hoses, baffled tank, filters, pumps and so on.
When looking at baffled tanks i think i prefer flat tanks compared to uprights, although ive no idea what size to go for. Wanting to go for a 2 man set up where i dont have to keep refilling because i run out, so need a bit of advice here.
The water tds here is around 130 so low enough. Would you then recommend a double di vessel setup? and have this inside the van with a hose connection? meaning i can for example when filling it just run a hose from back garden tap to the van either at my house or at a customers house if needing a top up/filling up?
For 2 men you will need at least a 600 litre tank, though I would go for 800 personally as I use at least 400 litres a day on my own.
Flat tank is fine, I have a 500 litre flat in the back of my dispatch. Just remember to mount the pump as low to the floor as possible or fit a non return valve.
With a TDs of 120 you will need an ro system or you will eat resin.
The good news is that a decent ro should polish a TDs of 120 down to almost zero. So you could just have an ro setup and use the water at a TDs of about 3, which is absolutely fine. Or stick a resin filter after the ro and the resin will last absolutely ages.
Personally I have my ro system mounted in an outside, insulated cupboard at home. I just pull up, stick the hose in the tank and leave it to fill for about 2 hours. You can have the ro system in the van but you have to be careful in the winter months that it doesn't freeze or can damage the membranes.
