Sorry new to all this.
I have a 450gpd I'm currently trying to set up in the garage, at the moment I'm missing bits like an in-line TDS meter and pressure gauge etc so not quite there. I'm not sure if I need a pump or not? The hose will go from the back garden, over a fence and around the front and into the garage.
What is the purpose of the pump, is it just to speed up production or is it because the the 450 won't work with a low pressure?
I saw this mentioned :

R.O's need a decent pressure to work at optimum
It'll increase production and lower your tds
The anount of hose you suggest between tap to r.o i would have thought you'll need one, but get a pressure gauge first. Anything under 40psi (which is likely) get a booster pump
-
Thanks Don.
The description on that pump I linked says "Simply install the pump inline between your prefilters and RO membranes".
Forgive me, but do I just buy some extra 1/4inch hose and fit it there? Or is there more to it...
-
You wont need any more hose mate
Cut the hose inbetween pre filters and membranes, put one side in the inlet and the other on the outlet (there should be arrows on the pump to show water direction so you'll know which is which)
-
And you then just run an extension lead from the house to the van? No good if it's raining. Or is it something else to hook to and drain the van battery!
I'd rather have something within the house that will increase my hot water flow for example (and the cold) and push the water out to the van quicker, rather than pull it from the outdoor tap.

Thanks Don, got it! :)
Chris I'm going garden hose>booster pump>450gpd RO>DI>1000ltr IBC>Submercible pump>25 litre barrels

Cheers BG, missed the "in the garage" bit!
-
Ahh lol :) Yep, got me thinking though - might not have the garage forever...
-
Iv got the pure water 350 gpd system and brought a new 500l tank and found in the mornings it wasn't full, (my water pressure is shocking)
Fitted this between the pre and r/o filters and it's working like a charm it's at least halved my fill up time and lowered my tds iv got pics of it fitted if you want me to send them too you.
-
Cheers mate that would be wonderful!
Can you pm pics etc on here or you want to email?

I can tx them to you or yer give me your email and il send them over.

Thanks - info@bluegiraffecleaning.co.uk

Thanks for the pics Tom, definatly gonna need some more hose. Where do you buy the white hose from? What size is it etc?
-
I got it from vyair, you can it off eBay as well just 1/4 hose.
And a couple of connectors for the pump I got from purefreedom.

I have an RO unit that I bought many years ago that has TWO of those same booster pumps on.
This is mine:
http://www.gapswater.co.uk/acatalog/FLEXEON-300-reverse-osmosis-system-2707.html (http://www.gapswater.co.uk/acatalog/FLEXEON-300-reverse-osmosis-system-2707.html)
(http://www.gapswater.co.uk/acatalog/titan300.jpg)
I'd never used it until a couple of weeks ago, since just after I bought it a mate of mine gave me a 4040 RO unit he had spare.
I fired it up for the first time (had to order a new power supply) and I have to say, for such a small unit it was very good. Produced exactly 1 litre per minute, so easily more than 1,000 litres a day no matter what the inlet pressure is. It even automatically flushes the membrane for 1 minute before starting, and every half hour while in use.
The twin pumps keep the membrane pressure at exactly 120psi.
Those pumps are great, the reason my unit needs 2 of them is because 1 pump can only produce a certain amount of flow, and not enough to feed the membrane. 2 pumps work a treat.

have got my booster pump before filters is this wrong
-
Just thought I'd update this, got all the bits (I think) that I need and have laid them all out.
Despite Tom kindly taking photos for me I'm still confused, I think Tom's RO is different to mine - so is hosed up slightly differently.
I'm trying to fit an in-line TDS meter, a pressure gauge, a pump to the RO.
There is about 3 different connections on this thing, I also need it to go out to my existing DI which has a hoselock connection (I have an adapter).
I've got no idea what's in and out and what goes where - Yes, I am ******* useless :)

Still trying to figure all this out if anyone can help.
I do have instructions for the pump but the instructions are for a Pure Freedom RO whereas mine is from elsewhere. The other bits I haven't got a clue how to fit, does the water go into the RO first or the pump first?
-
Okay in the end I tried to wire it up myself last night, unfortunately it was wrong somewhere - so I stripped it all back and now back to square one.
Is there a diagram somewhere that includes (Pump, water pressure meter, in-line TDS) with this particular RO?
I've not managed to find it on youtube or anything yet...
-
Water pressure metre wants to go after the pump, so find the hose that goes from the prefilters (blue cannister) to the membranes (white housings) (by the looks of your pics its the blue hose on the right of pic 1)
Your pump and pressure gauge want to go on this hose
Your inline tds metre ; you want the first t piece before the r.o and the sevond t pieces on your pure hose (the blue hose that all 3 membranes are joined with, on the left of pic 1)
-
The blue hose in pic 2, thats were the pump (1st) and pressue gauge (2nd) go
Take that hose out and use some of your spare hose to join them up
The red hose with the tap in pic 2 is your waste
Pic 3 pure- goes to D.I
Pic 4 normal water inlet(from mains tap)
My advice, set it back up as pic 1 (mines set up different but we'll not go there lol) and then add your pump etc...

Hi. thanks for your reply - I'm starting to get it (at last).
Some problems though :
I was told on a another window cleaning forum that the pump should be before the blue filters and to check with the manufacturer?
The info I had supplied with the pump from Pure Freedom doesn't make any sense to me as I don't have that RO.
I will post up what the info sheet says though :
"Locate the small white pipe which connects the outlet on the left most vertical pre-filter housing to the inlet on the first horizontal membrane housing and remove it.
Insert one length of the pipe supplied into the vertical filter outlet and connect this into the inlet of the pump. The flow direction is marked by arrows on the pump.
Insert the remaining piece of pipe into the outlet from the pump and connect to the inlet into the horizontal filter housing.
This will boost the pressure into the membrane housings and will ensure peak performance from your unit"
Second problem is when you mentioned the inline TDS meter "you want the first t piece before the r.o" - I can't put it before the RO because before the RO is normal (garden) hose??
-
The blue filters are your pre filters, and thecwhite are your actual membranes
So yes the pump wants to go after the blue filters and before the white.
Obviously the location of the pipe in between these are going to be different between different R.O manufacturers , hence me saying the blue hose in pic 2 is the hose you want the pump and pressure guage on
Just noticed your inlet hose will be normal hose do you may have to out the first t piece on the same hose as the booster pump
(One diode tells you your tap tds and one your pure, personally i wouldnt worry about the ingoing tds as much as it shouldnt change alot. Just use a handhemd tds metre every so often)
-
Thanks I got it setup, leaks everywhere at first - water flooding the garage but sorted out most of those.
Annoying drip down the sediment filter but will take that apart tomorrow and see if it's not aligned properly or something.
Gave it a flush out for an hour earlier (Red pipe is jetting out water, blue is slow trickle) pressure is the same (40) with pump off or on..
-
The red pipe should have more flow (waste) dont forget to flush it for a while first
The pressure should be higher with pump on (what psi is it?)
Check you have it plumbed in the right way round and in the right place
Maybe post a pic so someone can tell you whats what?
Or have you put the pressure gauge before the pump, a it wont show a difference if you have?
