Thanks alan will do,

will flush it for another few hours in morning too.

Jay from Grafters has bought a 40/40 from Pure freedom and his TDS is about 5-7 after RO. Our water here is about 450ppm sometimes a lot higher than that.

my tds is over 470 and I have a 4040, tds out about 19

[dave0123]

Im just flushing it for abit longer this morning see what happens.

[dave0123]

Alan you about?


just set pump up worked gr8 brought the TDS  down to 13 proberly will bring it down more just had to turn it off because of a leak lol which going 2 sort that out.

but 1 question on the gauges its still low states low pressure because i have installed the pump after the pre filters and after the 2 gauges so is that right? that it should be low its defrently doing its job tho its pumping out tuns of pure!

I had a pump before the prefilters myself worked perfect (cheers Jerry fosters)
I have it after the salt softener vessel.

your gauges will stay the same as your tap pressure because and I hope I am right on this the pump holds water then realeases at high pressure forcing it through the membrane.

yer just wanted to make sure..

so its boosting on the output stage of the pump..

yep

[alanwilson]

ok dave I'll go through this again

1 - sediment filter
2 - carbon filter
3 - booster pump
4 - in your case pressure guage
5 - 4040 membrane

You should have the guages AFTER the booster pump and before the membrane to know what pressure your membrane is operating under.

You want to run the membrane at 80 - 90psi.

[dave0123]

Thanks Alan,

iv set the two gauges before the pump aparently this is to let you know when the pre filteres need changing.. i have just stoped all the leaks haha dont want to change everything now... might just put another gauge between the pump and membrane as i have one spare.


dave

[dave0123]

Tompoole

just to let you know now i have my system running.

its alot better than the tiny little purefreedom RO. in normal use with my purefreedom RO i was getting it down to 24 with booster pump at getting 1 litre neally every 2mins just over about 28 lit per hour.

with the 4040 RO bringing the TDS down to 13 with booster pump and its a good pump really does the job! and now getting 1 litre of pure every 18 seconds 

so am happy means neally halfed my tds output so resin should last longer nice and easy to use.

Alan, why do you have the booster pump after pre filters ??

[dave0123]

RO man recomend his pump to go before prefilters even tho i tried both there was no diffrence. i just set mine up after prefilters as thats what everyone else on here seems to do.

[alanwilson]

I recommend the pump after the prefilters as

a) you won't lose operating pressure when the filters start to clog
b) you aren't subjecting the prefilter housings to prolonged (creep stress) where even though they are operating within their pressure limits they still may fracture over time - common engineering problem.
c) the water you are passing through the pump is filtered so less chance of dirt etc entering the pump.

hope this helps.

[dave0123]

Alan,


Thanks for all your help mate and everyone else it really is appreciated.

Just started filling my tank been running for 1 hour now and its just hit 200lit in the IBC from a empty tank


dave

[alanwilson]

dave not a problem, not a problem.

what pressure are you running the membrane at?

what is the tds coming out of the membrane?

[dave0123]

Not sure on the pressure am running it at yest Alan i set my gauges up before pump. Im just waiting on a T peice to connect between the pump and ro to show pressure.

the TDS coming down to 13-14 now so really pleased 

[alanwilson]

I still think your tds is far too high - I suppose you could just run 2 di vessels in-line after the ro in the same way as we do, resin costs are minimal too.

100% agree with that one, 2 di's will save alot on resin over a year.

Thats the lowest i can get it down to, i mite look into that soon once i have got some money back in the bank 


I flush this out every day as i dont fill my tank everyday so i keeping the system flushed so membrane does not dry out and also keeps it running top notch. only a few hours a day.
