Hi guys
I have a pure freedom GPD 450 RO unit and just wondering at what numbers you change the resin?
For some reason even when I change the resin the best it starts at is 004 and then ends up at 006 by the time I've filled a 1000 litre tank. I know the DI vessel that comes with it is pretty small.
Would you change resin if you were still below 010 in my shoes? I read a thread on here that 010 is fine so im assuming single figures of 004-009 are still ok?
-
I use 11ltr di bottles, these always seem fine, sometimes u can change the resin and it sits on 001, generally start to keep an eye on it when it starts to rise but 010 is ok
-
Would you change resin if you were still below 010 in my shoes?
Why would do your store water in your shoes?
What size do you take, btw?
-
Up to 10 is fine....I have worked with 45tds not knowing how high it was and had no complaints :D
-
Have changed the filters recently also but no idea why I can't get it to 000. Also it takes about 3 days to fill up my IBC 1000 litre tank although not a problem as enough for me.
I think making sure the resin canister is square is important also.
Would the type of resin help? Am using pure freedom. Have heard Gardiners is good?
-
I changed from a 1 Ltr resin vessel to an 11 ltr vessel at the end of November.
When I had the 1 ltr , it was rising to 001 after 1 week which was pi$$ing me off.
Iv had the 11 ltr for about 13 weeks now and it's still 000 coming out 🤔
I got my vessel ready filled from vyair, the other resin was either from pure freedom or gardiners for the 1ltr vessel

When you changed your filters, did you flush your RO for a bit?
If so, you'll find you still get a bit of pure coming out but at a much higher TDS, if you didn't disconnect your resin cannister you may have spanked through the resin
I used to have a 450 and used the poxy little resin 'vessel' it came with...about as useful as kick in the groin. Was changing resin once a week minimum....
Got a 25litre vessel, changed resin once a year (well twice a year now but use alot more water!)
-
I got the same ro and diy set up from pure freedom when i first started and was paranoid about the all perfect 000tds. It didnt take long for di to raise and so i ordered another small canister full of di. So i had 2 di's. Still didnt take long for it to rise. So switched to a 20" di instead. Again no joy. Now i use a 4.5ltr and that seems to suit my needs, tho an 11ltr as some have said would last you for quite a while.
Also be aware of tds creep. Be worth disconnecting ro before di and wait for initial level to drop. You may find the initial drain of as high as 075 or higher and that wont help your resin's life span.
A booster pump, i use a 60psi pump (made in china) and that will help speed your production up but also make your membranes more efficient.
-
Thanks guys. Question for Don.... I was under the impression the tiny little canister it comes with is the only one that fits without changing fittings? Would a 25 litre just connect without having to change fittings etc?
Yes I flush a fair bit but can't for the life of me get 000. Also what booster pump is best and can this be installed easily on this RO?
My water pressure is good by the way
-
010 is fine i change mine at 005 ish
-
I change mine when it gets to 001
-

the bigger the shoes the more water . But I would have thought it would be better to use wellies .

Very easy to sort out. At the end of RO, u should have like a TBar that feeds into your first membrane. Take that connection off and replace with an elbow connection. Then feed that to the booster and booster to your first membrane.
Whrn i got my 450gpd it came with 3 cannisters (sediment, and 2 carbon) and a forth being the DI. Simply feed it into a larger di vessel with suitable 1/4 connections. You can readily get them from ebay and keep them as push fit.
-
Great. Thanks Nathan. What pump is that? Can you advise exactly what connections I need(instructions for dummies) as I'm useless at this sort of thing. Can I get them from pure freedom also? Can you kindly put a step by step list for dummies what I need to get? :) thanks so much.
Ps how much improvement is it with a booster pump? How long to fill 1000 litres? Also my wife has gone mental at the water bill (on a meter) and was £370 for just under 4 months. Apparently there is a meter you can fix on this to prove all the water isn't going to sewage.
Can anyone advise on this?

Then just look on ebay for push fit 3/4 thread to 1/4 push fit. This will allow you to still use the blue pipe to connect to the new DI vessel and then whichever pipe + size connection for the outflow to your storage tank.
The booster pump in my opinion should be after your prefilters but before your membrane.
http://www.ebay.co.uk/itm/Reverse-Osmosis-RO-Unit-Booster-Pump-With-Transformer-and-Fittings-50-75-100gpd-/271391077970?var=&hash=item3f302b3652
This comes with 1/4 push fittings
My pressure reading is taken after the prefilters as shown in my photo. Without the pump on, i have about 35psi going through my membranes and into the DI, so this will slow it down more so. I think the membranes run more efficiently at 70 psi. My booster increases that psi to 65-70psi and takes roughly under 36hrs to fill 1000l ibc. (Currently filling my ibc from nearly empty, so might reset that time)

Answer these in order if you can...........
1; What is your tap water TDS?
2; How much water do you need a week ?
3; Are you on a meter ?
-
Thanks very much Nathan. Clean clear answer to your questions..
1... TDS tap water is around 354ppm(very hard water in Suffolk)
2... I use around 800-1000 litres a week from barrels but always like to have my IBC tank filled with back up water after I've filled around 800 odd litres into containers.
3. Yes on a water meter unfortunately. To fill my IBC tank the tap(which is installed in my garage is running non stop for around 36-48 hours to fill it up(that's without a booster pump)
Thanks
-
Nathan... is your pump the 50/75 or 100 GPD? As a few options. Also the fitting I have found on eBay is called John guest 1/4 pushfit to 3/4 BSP thread. Is that right? Also is it just one of them I need?
-
Thought it might be easier to take a few pics of my set up. You can see the RO and the tap installed above IBC tank. The waste pipe goes round the back of the tank and under garage door to an outside drain.
Do I need an elbow connection also Nathan?

My water pressure is good by the way
Aquatec 8800 is the best booster for that RO in my experience, its made from continuous use and is adjustable (you can change the pressure/psi to what you want)
You can fit what ever sized DI you like mate, all you need to do is put a 1/4" (thats your hose size) fitting on the inlet to the DI (the outlet can be any size you want as this is your pure and jusy goes into your storage tank)
Just a case of screwing it in with PTFE and then popping the hose from your RO into it
I got the 1/4" fitting from Daqua, wasn't much at all from memory, maybe around £3-£5, and was here the next day
-
Thanks Don. Where is the best place to buy the Aquatec pump? On Amazon U.K they are £327 so a lot more than the other pump Nathan suggested. Seen them used on eBay for around £159.
So if I bought a bigger DI vessel it's quite easy to remove the connection and replace with new fittings?(the 1/4 one)
Sorry I'm learning so much
-
Di tanks normally come with 3/4 fittings on. So look on ebay or other sites for a 3/4 to 1/4 push fit fitting. That will allow your pipe from ro to fit snug into the di vessel. You can even keep the outlet as a 3/4 and connect a normal hosepipe connection to it as that simply feeds into your ibc tank.
So i started to fill my virtually empty ibc tank yesterday 7pm, im about 200 -300 ltr short of it being full. So prob by 10pm. So about 27 or so hrs to fill it.
Not sure if this angle helps better, (http://www.cleanitup.co.uk/smf/1487963203_Screenshot_2017-02-24-19-05-58.png)

And yes, the fittings on the DI just screw off, you just need to make sure you order the correct fitting
I just rang Doug @ Daqua (daqua.co.uk) and asked him to send me the correct size, job jobbed
-
Thanks guys. Nathan what GPD did you buy on the pump? 50,75 or 100?
-
27 hours is a vast improvement so might go with your suggestions Nathan. Cheers Don also for advice. So to finalise I need....
Booster pump
3/4 to 1/4 fitting for Di vessel
New DI vessel
Anything else I need or is that it?
-
Hi Nathan, do you know what GPD on pump you got? 50/75 or 100?
Also is the fitting a 3/4 to 1/4 BSP thread? Is this what I put on the new Di vessel? Cheers
-
Ps I'm racking my brain trying to work out your set up Nathan as need to know what fittings I need.
So am I right in saying I need the pump which comes with correct fitting....... DI vessel....... and fittings as follows:
Elbow connection 1/4 inch....
3/4 to 1/4 thread to push fit connection( to put on Di vessel)
It looks like you might have two other connections to attach the pump to?
-
The water comes out your three prefilters into a bar like fitting which screws into the last prefilter. Which leads i think into first membrane and the flush kit. (Could be wrong as ive gone away 4 wknd). So you need a 1/4 push fit to replace that. Then feed that into the in let of the pump. The outlet from the pump would need to go into a 1/4 push fit T piece and then connect the tubing how it was originally. Thats all!
Yes your correct, the di would just need the suitabke connections as youve already said.
It will become easy when you have the parts in your hand.
All the best mate
-
Good man. Cheers Nathan. Have a good weekend away :)
-
Hi Nathan
Is your pump the 50,75 or 100GPD as there are 3 options at checkout?
Cheers. I'm ready to buy but don't want to buy the wrong version of pump.
-
I cant remember which one, but since i have 3 ×150gpd i probably opted for the 100
-
Ok cheers for the input Nathan
-
Right have bought the 4.6 litre Di to go with my 450 GPD (that Nathan recommended)as the 1 litre one is useless. TDS starts off at 005 now and an hour later up to 008/010.
Have also bought 2 x John guest 3/4 to 1/4 pushfit. So do I need one for the inlet and one for the outlet?
And I simply unscrew fitting in Di and replace with these fittings? Is that right?
-
Ps. Changed resin 3 times in a row and wasted loads thinking that would help. I'm hoping the new DI vessel will help. Filters been changed recently and have flushed lots so can't think what else it can be
-
The last post, is that with the new di vessel fitted and with the pump??
When ive time later today i'll take a quick video of how mine is set up and tds before RO, after RO and DI so can see how mine is set up.
-
Don't use above 003 otherwise you'll get spotting on glass if using ro keep flushed about twice week if hard water area
-
Hi Nathan. No ive only just ordered the new Di and fittings. I'm not worried about the pump right now as I just need to get the TDS back down again and happy to sort pump later.
Just need to know about fitting. The little 1 litre I have has the blue (1/4) hose going in one end of the Di and the red hose(one that leads into tank producing pure) going in the other end of th Di
So my question is..... Do I put a fitting(3/4 to 1/4 pushfit which I've bought) into both the outlet and inlet of Di vessel? That's why I've bought X 2 fittings. Or is it a different fitting to the outlet than the inlet(Di vessel I'm talking about) have bought the same Di from link you sent earlier in post. Cheers
-
Lynda. I've been told working with 010 is ok. My water this week has been 006 and I've had no spotting at all.
-
Don't use above 003 otherwise you'll get spotting on glass if using ro keep flushed about twice week if hard water area
been using water at 010 for the last 2 years, it is what I get after RO, don't use DI, never had any complaint.
-

Sorry but your talking rubbish.

Sorry bud, not had time to do vid yet.
The main thing on di is changing the connection on the inlet to the 1/4, so you can simply push the blue hose in. It makes no difference really to the outlet as that just takes your pure to the tank. But if you have it all set up with the red hose, then yes use the 1/4 new connection so its basically what you have now but with a larger di vessel
-
Cheers Nathan. I have ordered the new Di and 2 X fittings(due end of week I think) So will keep you updated. I'm hoping a new Di will sort it. Can look at fixing the pump later but main thing is to get TDS back down again. :)
-
Heres a link to a quick vid but firat a couple of excuses ;D
My thumb nail is disgusting, trapped it in car door n then punctured nail to get blood out so it looks a little gross.
Also, i should have checked my di tds first, it finishes at 002 or 003 cant remember now, but ive been using it for several months, but the thing to take note of is the tds creep.

Thanks Nathan. Sorry for delayed response(this is the first time I've signed on here for a few days)
New Di has arrived today with my 3/4 to 1/4 fittings. Very easy to put fittings on. The water has finally come out at 000 YAY. It must of been the poxy little vessel. It's been on all day and still 000. Will take a look at video now as time to look at getting a pump fitted to speed it up a bit. Cheers
-
I have never disconnected Di though like you have. I just set up new Di and flushed for ages then switched to produce pure and it's been 000 all day. I don't know how important it is to disconnect Di? Be interesting to see how long it lasts before TDS creeps up. I need to look at those pictures you sent in the earlier replies as need to work out what fittings I need to attach booster pump.
-
It's not massively important to disconnect DI when flushing but it can only help.
When flushing, your RO still produces pure (not a lot though) but at a higher TDS , so this will obviously be going through your resin (although with a 450gpd RO, it wont be much)
-
Cheers Don. The weird thing is when I flush the TDS is actually 000 and then again 000 when I turn switch to produce. No idea why that is? Not complaining though as 000 is great :)
-
It'll still be 0ppm whether you're flushing or not mate
Resin is designed to get you 0ppm whether you're putting 300ppm into it or 6ppm
By putting a lower ingoing TDS though, you are prolonging the life of your resin as it 'does't have to work as hard to filter the water'(it's not quite as literal as that but it's the best way to describe it!)
So...when flushing, you'll be putting a higher TDS through your resin (albeit not a lot) so you'll still get 000ppm, you'll just use a bit more resin to get to 0 then you would if you have your tap set to pure
The best way to check and see the difference is disconnect the DI. Test the TDS of the water that would normally go in to the DI when your RO is set to flush, and then when its set to produce. That will then show you what TDS you are putting through your resin
Like I said, the amount is negligible but it cant do any harm to disconnect whilst flushing (I always have on my 4040)
-
Could be wrong but back flushing doesnt prevent tds creep.
When membranes are under pressure (being used) it seperates particles in the membranes; purified at one side and not at the other. So if the membrane is not under constant pressure, the two sides no longer stay seperated and mix. Thats why the tds is much higher coming through first. As in my vid the tap water was something like 280. The first lot of water for first 2 or 3 mins was coming out just over 200. So i disconnect so im not adding that to the di.
Just an extra prolonging of di life.

Thanks for the input. Gone with the days of just a ladder and squeegee although I would never go back trad in a million years. Best thing I ever did was move over to wfp

Ditto, i think weve all uttered the words;
" why didnt i do it sooner"
Though i agree, sometimes the ease of just putting your ladders away and washing the scrims sounds appealing
-
I'm only 37 and had 18 years on a ladder and the last two years wfp. It was scary at first the changeover but I honestly couldn't imagine getting up a ladder all day long now. I don't want to be in my 50's climbing a ladder(no disrespect to any older trad members). It had to be WFP all the way. I still have a squeegee for the occasional indoor work though.

Very similar story, im 39 and just over 15yrs experience and last 2 on wfp.
When on trad i knew my work very well, the clients, the houses, gardens and windows. So i could put the ladder down and before it touched the sill i would almost be at the top. Or the odd window you needed to bounce the ladder a fraction to get to. And then after almost a year on wfp i had to go up a ladder for something and all my confidence left. I didnt enjoy it and so if i helped my mate on his round again, even though i was much faster than him upstairs, i told him im not on ladders any more.
-
Made me laugh Nathan about the bouncing the ladder Lol. I used to do that and literally run up them. Like yourself I would hate to go up one now
