I am thinking of going WFP but would like to know how to purify water and cheaply?

If someone could say exactly what I need and recommend some items/places to buy, it would be greatly appreciated.

Does the treated water need to be tested after? With what?

Thanks in advanced!

buy a tds meter, to find out what your water tds is,
then you will either need a ro and di ( hard water )
or di only ( soft water )

before you can really answer any of those questions mate you need to find out what the TDS is of your water you can then go from there.

Thanks for the replies.

So buy this?

Than can someone elaborate what I would need to do, how to examine the results and also what to buy next.

From research most of Britain's water is hard. Whats your opinions on that?

Please could someone recommend a cheap and suitable r/o and d/i?

Thanks in advanced.

First of all - before you think of anything else, buy the TDS meter and use it to check your tap water. A TDS meter will be an important part of your kit to be used regularily with WFP (like a carpenter's hammer).

Once you have done that come back with those readings.

Also tell us what equipment you are going to start off with - (what your finances or budget will allow), back pack - van mount, water meter situation etc and then we will be in a better position to help you. Producing pure water cheaply is a contradiction of terms in my experience - best value for money, safer working environment are better phrases.

There are parts of the country where the water is not hard so you could get away with a DI only.

As you have posted many times on here you must be trad so do a search over the last few years of Dazmonds posts on his change over to WFP and you will find many of his post will apply to you.

Thanks for the reply's.

I shall buy a TDS meter and get back with results.

Where abouts are you, this will gives an idea on your tds

I'd be looking at getting this..........

and if you have low water pressure then you probably better getting a pump. I've no idea what the difference is between soft and hard water, as in where is the line. But even in a soft water like mine (90tds) its still cost efficient to run an RO. I think its only cost effective to use DI only if you don;t use a lot of water and have very soft water.
I'd be expecting a pumped Merlin to produce water of a quality of below 10 TDS and i would not use resin either, just use as is.

Something else to think about is how you will produce once you know your tds

di - fill van tank
ro & di - fill van tank
ro & di - storage tank

All depends on TDS & if you have space for a storage tank or fill straight to the van

Hi Mike,

We have water at 90ppm in the North East and not being on a meter, it does pay to run an R/O. But if I was on a meter I would probably go DI only and look at rain water harvesting to supplement my water needs to keep water costs down.

I'm in Newbury, if you can't find someone nearer to work a day with to learn how to use wfp, you are welcome here.

[Ian Sheppard]

You could do worse than have a browse on the net there are several good WFP supply companies out there that spring to Mind.
I am sure the guys here will point you in the right direction as to who to speak to

You're right mate. I'm not on a water meter myself so i always forget that that can be part of the equasion.
