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

[Clever Forum Name]

About 5 mins when I first got it.

[elite mike]

flush for an hour then retest it should settle down then

[Clever Forum Name]

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

[Clever Forum Name]

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?

[Clever Forum Name]

The only thing i think is weird is the pure is faster than the waste lol.

[p1w1]

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.

[Clever Forum Name]

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

[elite mike]

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.

[Clever Forum Name]

I dont know if anything is wrong though?

380 tap in 30 tds out

Deffo not got a flow thingy

[elite mike]

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 .

[Clever Forum Name]

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

[elite mike]

can i ask what your water pressure is
