Just set up my HF4 4040.
TDS in 360-ish
60psi
Cant seem to get output TDS lower than 40?!
Any guesses?!
-
Cant speak to GAPS as they are closed... :-[
-
Have you flushed it (you need to do this for at least an hour) then run it for another hour then check it will come down. Even more over the coming days, thats what mine have done anyway!
-
an hour? ok, will try that.
with the waste fully open?
-
yep!
-
Will give it a go, as so far, my Merlin may not be retired just yet!!!
-
as per TC
flush !
test again in an hour or longer -- my tds is 320 and i'm getting 003 out ;D happy days.
( merlin at it's best was 009 - but after 2 years and making approx 160,000 ltrs of pure it had crept
upto 30 ! )

cheers guys, its now sat flushing out.
will check it in a bit and report back.
Gaps paperwork says 10 minutes flush?!

once its "bedded in" new ro can take a couple of hours to flush then once a week for 10 minutes .... not that Im one to give advice as flush mine about every 2 months as keep forgetting but then flush it for an hour
-
what sort of ro/waste ratio do you guys run?
-
HF5 4040 ... tds in of about 180 to 220 varies during year and tds out of 3 to 5
changed my prefilters and dropped from tds out of 10
my resin has lasted for 6 months but tds has SHOT UP to 2 after di so best change resin ;D
-
Regular flushing is much more important then doing it once a week for an hour. For every fill flush it for 10min. This also helps get the air out of the membrane, membranes which are not wet properly fail.
Is it a new housing? New membrane?
Internal O rings (which seperate waste and feed from pure) can wear and need to be replaced after time.
-
Brand new set up yes.
-
>:( >:( >:(
36!!! Thats after over an hour and a half of flushing, and the waste almost maximum, so RO water is just trickling out.
This cant be right surely?
My Merlin with 2 year old filters produces more and better quality ???
-
do you wanna bring it over on monday and i'll compare it with one of mine?
may rule out if theres a problem
-
Will chat to Gaps first. It has to be something simple like membrane not sitting right...has to be, or else I will stick to my Merlin!!!
-
ok, you actually seen how much it produces yet even if its at 36?
-
Yep, just a dribble.. :o
-
Somethings not right there mate. I'm getting 400 liters an hour off a single hf5
-
No one got any clues to what it might be?
-
The tap your using to adjust the waste/ pure
Ratio may be faulty! If you are turning the tap
Half way you should be getting 50% waste
50% pure if your not getting that then you've got
A problem!! Your waste pipe is definatley coming out
Of the bottom and good from the end I assume, on the waste
Pipe is were your tap should be! If all that is correct
Then you should be getting better readings!!
-
P.s if you want to give me a call I will try
And talk you through the set up.

hf5 is better apparently for low pressure. yes making sure got proper waste setup. no kinks or blockage on either pipe restricting flow, it could he something obvious that if your new can't see. got pre filters in correctly? wondering whether your tap pressure or flow is good enough, might need to check static tap pressure? or use booster pump
-
He's using a booster pump, tap faulty? Come on you can come up with a better reason than that ;D
-
Did you make sure you inserted the membrane the right way? There is a plastic white rubber flange that needs to go in last. Your feed water needs to go in that end as well.
Make sure your RO is setup so it's running around 70% waste, 30% pure.
-

can't see where it says about booster pump.....?!
its got to be either duff filter, or inserted incorrectly. you haven't blown it by running it with tap closed have u? you say 60psi, that seems ok pressure, was that taken from the system pressure gauges, and if so, what waste to pure ratio was it setup at (as that varies when change waste gauge obviously)?
all I've got I'm afraid!
-
Try the process of elimination :) remove the pre filters from their housings and see if you still have the same problem, if you dont you know the problem is with the pre filters and not the RO.
If your using a 40/40 you've probably got a 20" particular filter and a 20" carbon filter? is the carbon filter granulated or a block filter? I only use the block filters as I had problems with the granulated variety which resulted in the mains water after booster pump not being able to pass through the carbon filter "this resulted in low pressure" have you got a water softener before your RO?
June's the Lady to speak to at Gaps she knows her stuff and will sort you out if you call her tomorrow :)

Hi all, why we are on membranes, where Is the best place to get my self a new 4040 hf5 replacement membrane filter at a good price, would it be caps.
-
12 months ago the cheapest was Ionics but these here might be right now or are as cheap as i have seen so far.
http://www.daqua.co.uk/reverseosmosis.htm,
Ionics is £246.00 delivered,the above is £216.00 delivered.
-
Back on the thread topic,the first thing i would do is take out the membrane,apply vaseline to the sealing rings and re-install. You might just be getting some seepage.

Cheapest isnt always best, but after service also should be taken into comparison. June at Gaps water on 01706 521074 has never let me down, always answers the phone and very knowledgeable, dont think they are far off the best price either, it at all.

I`ll second that,the price differences have levelled out since 12 months ago,i remember June from Gaps saying there was a bit of price control for membranes in Europe as compared to the U.S. so back then the Ionics HF5 stood out as a bargain compared to elsewhere.
So if you want to be 4040,its 1 phonecall and all the advice you need,the HF5 is 189.00 plus vat from Gaps now.

Never ever use vaseline on o-rings, it makes them brittle and slowly eats away at the them. You can get special lubricants for O rings, or just use a bit of vegetable oil.
