Purchased a 450 GPD from colins water.
It's only a temporary solution but the results are quite weird.
Input TDS is 360PPM
Output PURE PPM is 30PPM
Waste PPM is 920PPM
The tds meter is brand new and reads the same as 4 others.
The waste is just a slow trickle. The pure is a lot faster.
Doesn't sound normal to me?
-
how long have you flushed it for
-
About 5 mins when I first got it.
-
flush for an hour then retest it should settle down then
-
An hour. Blimey ok lol. Thanks.
-
Flushed for an hour same results.
Can you change the waste to pure ratio on these units?
Do you fit a valve or something??

did it not come with a flow restrictor

Yeah i think it did but not a 100% sure what i am looking for. I never installed the original RO production :( So this is all new to me :(

i am surprised by that ,i use a unit by the same firm and flushed for around half an hour , tds was coming out at around five so flushed for another half an hour and its coming out at 000 no resin :) water pressure is over 100 psi and the tap tds is normally 230 sometimes less and has been pretty constant for around two years now .like i said let it go and let it settle down hopefully ;)

your flow restrictor will look like this http://www.ro-man.com/shop/index.php?route=product/product&product_id=206 this needs to be put on your waste outlet after your membranes.

these ro s come ready to go all you should have had to do is put the filters and ro membranes in , and as long as these have been put in correctly you should have had no problems, i think some of your membranes may of been incorrectly installed possibly
-
Pretty sure it was installed correctly.
Double checked everything and used Vaseline on the seals.
The pre filters are in the right order and the membranes could only go in one way.
I dont have a waste flow restrictor. What do they actually do, i know they create pressure. I am assuming the Ro machine produces less waste and more pure. But with it producing more pure i am assuming the TDS of the pure that is made will go up?
-
The only thing i think is weird is the pure is faster than the waste lol.
-
flow restrictor creates back pressure on your membranes you need to put one on really (i'm guessing its the standard 3x150gpd membrane type r/o)
not having one may increase your pure water output but the membranes wont last long and they could get damaged. you can get them for less then a tenner but make sure you get a 450gpd flow restrictor. Give ro man a bell there very helpful you can get one that lets you flush your system for about a tenner.
-
Yeah but if i fit one? Will it lower the TDS on the pure thats made bud?
Its only a temporary solution, can bin it after 3 months lol
-
you should have a flow restrictor on the unit,should look like this

if you are not happy with this ro ian i would tell collins water products what is happening and ask their advice as they are pretty good service wise, i would think they will offer you a full refund or send another unit out to you.
-
I dont know if anything is wrong though?
380 tap in 30 tds out
Deffo not got a flow thingy :)
-
in the morning i will take a pic of my FR on my unit as mine is from the same firm,just to comfirm , in the meantime let it flow full belt and take a reading 2morow, but like i say contact them and let them know as its such a new unit .
-
Ok thanks, will go switch it on and see what its like in the morning.
Just trying to find instructions as positive no mention of FR
-
can i ask what your water pressure is
-
can i ask what your water pressure is
I don't know buts its well above average. With the tap flat out its like a pressure washer mate. I will try and get a reading tomorrow.
Pure tds is 25 PPM
Waste tds is 810PPM and cloudy!!!
-
ha ha dont worry about the waste just the pure at least its coming down 8)
-
Gonna be up all night taking readings lol.
Thanks for the help guys.
-
sorry ian cannot get the damn phone to take a pic ::)roll
but there is a little sticker on my FR that says qc/4 ;D if thats any help good luck .
-
Will go have a look, couldnt produce over night, as needed to produce from other Ro (as i know it works lol)
-
Just uploading one now, deffo nothing to fit onto the waste.
This is the only thing remotely that looks like a FR
-
Thats your flow restrictor.
Ive got a 450 from collins, left it to run a few hours and it worked fine after that...
What seems odd is your waste/pure ratio, also i would personally think your tds should be lower....
Have you given lee a ring?(from collins) hes a pretty helpful guy...
Edit : if you havent got it sorted later i'll take a few photos of how mines plumbed.
Although its simple enough as they're in parallel
-
Bugger i ordered one last night from ebay lol!!!!
Ah well only £6 lol
It is producing water now, so i will take some reading today.
I havent called him yet, as like i say is anything wrong?
Reemeber its just tap pressure and i have 360 - 400 PPM tap water?
With my math i should be producing 12TDS pure upwards ? lol
-
Right
Pure rate has slowed down as has waste.
Pure is 25PPM and waste is 660PPM NON cloudy.
So i will let it produce all day and see what it does later
Thanks so far guys :)
-
I know you are all excited to hear the next update. 22/23PPM
-
I flushed my ro for 24 hours when i first got it. :)
-
Went to check it again and it's dropped to 20 PPM so that's good.
Decided to flush it for a few hours. Can't hurt lol
-
Leave it running mate, not on flush and it'll settle out after around 2hours (ish)
Think its a case of it getting out all the air and what ever else is knocking about when they're new
-
Back to running now it producing at 18PPM whoop whoop
-
Been testing water production today and really happy with it.
TDS is around 15PPM
It's producing water at a rate of 1L per 1min 45 secs.
so 1000L in pretty much 24hrs.
Its only a temporary solution, but really happy with results.
Thanks to everyone that replied :)
