Hiya all,
Hope ya sound
dont know if any ov ya have seen my problem with my new low pressure ro-
Here's the link if ya intrested....http://www.cleanitup.co.uk/smf/index.php?topic=107125.0

Thank you again guy's for the help with this.....

I was thinking could i reverse,like backflush the membrain on the HF5 membrain guy's???
As if something is there at the start of my membrain creeping my tds up maybee a reverse flush might release whatever it is what's come from my softner??
I'v taken the water inlet pipe off & poured nice water in it to flush it a bit,but maybee a bit of pressure might do the job....
I'm talking about swapping waste pipe with water inlet & vice versa etc....

Anyone think this is a good idea ,as the membrain's are expensive or do you think i should leave it @ 25ppm for a bit c wot happens after a week or 2?

Any help much appreciated fella's

Take care & kind regards
Justin

1st question:  What's your incoming tds?

[C-N-C]

Hiya Ian
500 ish mate.....i know its high,but it use to come out @14ppm until i added manual softner & never regenarated beads often enough,then it's rose slowley.....
Couple guy's recon that's wot i should be getting & a couple recon it should be 11-14ppm coming out.....
Strange tho how it use to produce 14ppm for the first 6 weeks

Take care mate
Justin

Hiya guy's
surely someone out there must know if you can backflush 40/40 HF5 membrain.....
I'm not 100% sure,but i think you can do it with a lot of RO system's...but i'm not sure about this one ?

Any advice will be much appreciated

Kindest regards fella's

In theory you should be able to put a feed to your waste output, direct your product outlet to waste and your inlet (now producing flushed water) to waste. I've no reason to think this would not work, nor should it damage anything. But i'm not so sure its going to cure the recent problems you have had. Did you manage to resolve the issue where the two pressure gauges had different readings?

[luther1]

Its not been used enough to warrant backflushing as there shouldn't be a build up of solids attached to the membrane. You could try it though for 5 minutes to see if there is a drop in your tds reading.

Hiya mike
Thank you for taking the time to post mate
I might just give that a go mike ,if no one elese post's saying not to
i'v been told the first houseing gauge will alway's read a bit more on flush only...
When system running they just about the same...
It's strange mike...i marked drain tap etc & got 30 psi going in ro & that was producing 14ppm..... now when i put tap @ same place the psi rises to 40psi......altho summit is blocking it a bit & sending psi up???
When i spoke to gap's they said it's because iv probaly clogged membrain up a lil bit a result of not regenarating softner beads enough....so i thought if i could send water back the opposite way it might push whatever it is back out of membrain........
Just a thought....

Thank you for your time mike ......ya sound dude

Kindest regards

Hiya luther mate
Yep ya right mate...it's brand new.....why do you think it could clogg up so soon???
surely this softner hasnt done this,has it?
I will try & flush the other way c what happen's
Thank you for ya time fella 

Take care luther mate& kindest regards

They should both read the same anytime. But you say thats ok now? Try not to go by your previous markers on your drain tap as things like water temperature,TDS and water pressure can and do differ on a daily basis and this will affect where your drain taps optimum setting will be. Just start from scratch and look for the best setting for it.

Hiya again mike mate.....

They should both read the same anytime.

weird that tho mike, first filter housing more psi than other ,wonder y they diffrent as when i first got system both were the same.......infact first filter gauge hardly moved & second never moved at all with drain fully open...wonder y now ,even on flush(drain fully open) first gauge reads 10psi,were when new it never hardly moved?
I'v changed filters etc....HMMMMM!!!!.....wonder if thats out to do wid it.....

That's wot i tried mike as in winter the water is thicker etc...ppm more(i think )
So i adjusted the drain & the best reading i got is 23...then after a bit it goes to 25ppm
I carnt get past the fact of, when new, the first housing gauge never hardly moved when i turned water on...now its registering 10psi & seems that the drain has to be opened more to get it down to the psi i marked on gauges.....the problem must be.....i just havnt got a clue mike...LOL
Gunna try & flush other way tommorow (might b weekend now)& c if that makes it any better

Thank you so much for ya time mike....ya sound dude

Kindest regards

Only 1 gauge is working on mine on flush which is the first one, the second one hardly reads anything but when I turn mine to produce both gauges read about the same.

I get both gauges at around 25 psi when producing pure water, 300 tds in, about 17 out.

Hiya steve mate...
I thought you'd told me before ,your's was the same
Thank you for that mate....
If i'v got 550 ish going in & 25 coming out...that sound's okay to me ste mate,judgeing by your inlet & outlet

The only thing is mate....i would of probaly bin okay with 25 coming out,but,when i first got system,that 14ppm was lovely I was doing cartwheel's
Just a bit dissapointed when it has rose so high dude

Thank you again for ya post steve bud
I'm still gunna backflush it........in fact....might not even bother mate,might just leave it as it is   im sick to death of messing around wid it man

Thank's again dude & you take care

Kindest regards

Justin, have you tried the pre filter change ?, you have not been using it long and I doubt you could have screwed a membrane so quick with using a softner also, unless you did not flush the softner properly ?,

I myself would back flush the membrane, I am not saying I am right just what I would do.

back flush, test, see what happens, change pre filters test see what happens,  if dud and membrane is not old at all as in months I would be asking gaps for a replacement should they not be able to locate problem and sort it, I had this  problem with a membrane with purefreedom, they sent me out a new one after fault finding first.

I have no softner and tds of 480+ I have had 1 membrane for over 2 years running daily and get tds out at about 14 unpumped.

Hiya ian
you alright mate?

Justin, have you tried the pre filter change ?, you have not been using it long and I doubt you could have screwed a membrane so quick with using a softner also, unless you did not flush the softner properly ?,

yep mate,only had system bout 6 weeks & still changed, filter's sediment & carbon
As for what you said abot not flushing softner properly.....i never dude  :
I used a old di bottle filled with softner beads,then disconected it from RO & conected it to 10" filter housing,filled it 3 quarter's full ov dishwasher salt & it took ALL day to flush salts through to drain(not through ro)......i done this once a week,june from gap's said i should ov be doing it everyday   & she said that's wot the problem is....clogged up...with what tho ian?
I'v now disconected softner & only had it on system few weeks maybee a month,so i didnt think that would cause damage......

I will now backflush this weekend ian, as i need the ro water @ the minute,however high....
What worries me, is that gap's might say that i'v broke membrain & refuse to help out or even test.....
They did say it SHOULD go back down after a bit.........not to sure tho bud,but they know there stuff,i hope...LOL...

I have no softner and tds of 480+ I have had 1 membrane for over 2 years running daily and get tds out at about 14 unpumped.

That's sound man...iv had nawt but problem's for a while now mate...even bought new membrains for merlin then sold it, because id had enough of wasting time playing around with it
so i bought this new 40/40.....& having the same problems again...feel like shotting the towel in bud

Anyway ian thank you mate for ya post man

Ya sound fella

Kindest regards
Justin
