Need advice on a purification system.

[Luke Macclesfield]

Afternoon all

Im just looking for some advice on a decent purification system and what I need to order. I would really appreciate any advise. ?

I bought a van and a system last week and it doesn’t have the purification system built in. I’ve been purifying my water with a di vessel, I’ve heard this method is expensive as I will have to buy ressin quite often.. What do people think of that method?

And what would be the best method to use? To produce 100% pure water and not take hours and hours to fill my tank?

Also please can you recommend the best place to buy the equipment? 

Would the system in the picture be adequate? 

Many Thanks

Luke

The first question is what’s your tds reading of your tap water ?. This will determine the type of filtration youbwill need , but an ro system will give you a more cost effective way of producing water if the reading is higher than around 90-100 , buy a tds meter they cost around £15-20 for a decent one and see what reading you have first .

what you have put up picture wise is a reasonable system and seams quite cheap to me should be ok 

To run an ro system you also need to know an approximate water pressures from your tap as most membranes need a minimum of 60-100 psi depending on type tk work efficiently and produce a reasonable volume of water

What @Pjj says regarding your tap water tds is the first step.

Now lets talk used r/o units.

You can buy a brand new 4040 r/o for £650 from Daqua. You already have a di vessel.

Now this person wants £450 which includes a di vessel.

Nowhere has this seller listed how efficiently his r/o is that he has for sale. So as a buyer you need to work out what this second hand r/o is actually worth if you have to replace prefilters and a membrane.

We should always repalce the prefilters but must assume that we will need to replace the membrane pretty soon after purchase. (If it lasts for years then we are quids in.)

To replace the membrane is £326.00 and the 2 prefilters are the best part of £40. You can swallow the price of prefilters but if you have to replace the membrane you have already paid out more than a new r/o. (£450 + £326 = £776.

So in my 'books' that r/o is only worth the second hand value of the housings - £100 at most.

Ah I assumed it was brand new not second hand @spruce  you are right if that’s the case better off buying new didn’t think about it being used ???

Looking at the add again it clearly says used !!!! Missed that bit ????

Thanks for your reply ?

I’m not sure tbh mate I live in Stoke on Trent. I’ve ordered a TDS metre from eBay for £5.99 hope it does the job properly.. I will test it when it arrives.

Having had a quick look on ebay the one i was given as a freebie (with the water tank and RO i got super cheap on ebay) would appear to be a cheapie. Seems to work alright though, stick it in tap water, it shoots up. Stick it in a barrel of spotless and it's a 0 every time. Stick it in the RO from my unit (when i can get any water out of it lol) and i get 6 or 7ppm so it seems to know what its doing.

Must admit i can't quite see how two electrical conductivity probes can tell how much chlorine, calcium, magnesium, flouride etc is in the water but apparently it does..

Haven't dared stick it in a water reservoir like Bewl or the sea lol
