Good afternoon.
It's not a bad system if it holds and pumps water.
I'd personally strip the flush mount connector panel of It's fittings then bin it.
There's no need to hack anymore holes in a van.
Talking about vans, I hope you have one that can legally accommodate the system and it's weight along with yourself and all associated cleaning equipment.
I'm sure a local window cleaner would help you out for beer money
What is your water quality like near you?
Do you intend to produce water at home or purchase from spotless?
Have you a reputable TDS tester?
You'll most likely need new resin etc.
I recommend you read up on water fed pole van mounted system and familiarise yourself with all the component parts so you know what they are.
The Brodex website along with this forum would be good reading
Hi mate thanks for your help I have no problem with van 31/2 tons I would like to make my own from homeGood afternoon.

The first step would be to test your home tds and also water pressure at the tap you'll intend to use for water production.Hi mate thanks for your help I have no problem with van 31/2 tons I would like to make my own from home
HM Digital TDS-3 Handheld Meter With Carrying CaseHi what beast make of TDS tester should I buy ?
With water that hard I'd be at the estate agentsHi all Thank you for all the help I have a water tester it coming with 328 ?
with thanks Mark
Mines minimum 340 out the tap lol.With water that hard I'd be at the estate agents
Thats a reward for having to live in Manchester ?????mines 024 out of the tap......im very lucky!
Stay away from 5hitty ebay and supply some proper trade suppliers if you want qualityHi Also I think of getting one of these first of all will I need have a pump to push water through with the pressure I’ve got ?
With thanks
Mark

055 is not good but @spruce is the man to explain your rejection rate in % terms at that level you will be using a lot of resin .Membranes I have been asked to run water through so I have done reading 055 i think its good from 328 ? 1 litre in about 2 1/2 what’s your thoughts ?
You will always assume that anyone buying a used r/o will have to replace membranes and prefilters. These are expensive and is probably the reason why the original owner decided to sell it.

Ok not good new in some way but leaning curve I thought would need 3 stage filter be for the membrane any way may be will have to replaced it has Well I really appreciate your time explaining this tho thanksYou will always assume that anyone selling a used r/o strength will have to replace membranes and prefilters.

For a membrane to be working efficiently it need the correct water pressure for the make and variant of the membrane. It also needs sufficient water flow at that pressure.
The membrane needs to have a pure to waste ratio of around 2 waste to 1 pure whilst producing water. It needs to be tuned to find it's sweet spot.
An efficiently performing membrane will remove around 97 to 98% of the impurities in the water. When the efficiently gets to around 94% then you should consider replacing the membrane.
At 55ppm before resin your r/o is only 83% efficient. The pure leaving your r/o should be around 10ppm or lower.
It's important to know your water pressure. An Axeon HF4 need a higher water pressure that an HF5. My HF5 is happy with 50psi. An hf4 needs around 80psi
Brodex only provide 1 prefilter. They fit a sediment into it. They don't fit a carbon block as they expect not using one will reduce membranes longevity and lead to increased sales.
You can take the sediment filter out and replace it with a Fiberdyne carbon block which can act as a sediment filter combo.
You also need to strip the di vessel down and check it very thoroughly. Brodex like to not fit a sealing o ring in the filter head where the pipe to the lower basket fits into the head. This gives the indication that the resin is depleted as all the resin in the Di vessel isn't being used.
