I have tried everything taken everything apart again and again, I cant get more than a liter of pure water a minute , lowest tds i can get is 17, psi can get upto 60, just doesn't seem to work as it should, everything is new, going to test it on a friends system if i get same results company that sold it said will take back and check for me ( thats cool), anyone any miracle ideas.
-
What ratio of pure to waste are you running ? on a new membrane you should be looking at around 50/50.
-
it,s about 2.5 to 1 but the system is not producing enough overall for the psi
-
How have you fit the inlet hose to the tap your using?
i.e have you hose locked it onto the tap, or is it just a barb fitting?
Check you havent put ptfe over the connectors hole stemming the flow of water, or maybe try a different connector if you've used one..?
Just make sure you've got a good amount of flow coming out of said tap is what I'm sayinh, mate of mine had a spilt hose lock feed on his merlin
Had a similar problem, turned out he hadn't fully opened up the tap on the outlet he was trying to use and the R.O wasn't getting enough water
-
cheers mate tried all of that, using a hose lock fitting, tried a few different ones, the flow going into the 4040 seems fine and powerful, coming out the other end not so good, have changed all connectors, disconnected everything, one hose goes in, two out and nothing else, still slow production, this suggests to me something in the 4040 but no idea what.
-
Shouldn't psi be 80?
-
well yes but with 50-60 should be getting better results I'm led to believe

I reckon you need a pump. That's the problem.
-
maybe in time but according to company who sold it should be getting alot better results, its Hf5 filter, designed to work at low psi, it takes forever to produce 1000 ltrs, should be better than this

Low PSI is about 80 I think for 4040s. Who did you buy it from?
-
low is 40 to 50 , gaps i got it from, they are really good.
-
Iv never had a 4040 but I know they have high and low pressure membranes is the right one fitted for your tap pressure.
-
ordered hf5 for low, i think thats what i got ::)roll
-
Get one of these to first test the tap pressure and go from there http://www.screwfix.com/p/monument-tools-mains-water-pressure-test-gauge/82412?_requestid=293002
-
Have one built into system smurf, says 60psi, thanks for all suggestions will see what happens on mates system tomorrow, will let you know just in case any ones interested, cheers
-
Do a flow rate test on the tap too as both have an impact on ro's production rate.
-
I take it you're getting a shed load of waste then?
If you're not getting much from either waste or pure then you're getting a restriction on flow somewhere...
I've got a HF5 unboosted, water pressure is about 35-40psi (i really ought to get a pump just haven't got around to it!) and I get 100 litres in under an hour (40-60 pure - waste) so you should definitley be getting better than you are
If you open your gate valve fully and then open it up slowly, can you see the difference in pure production?
-
Membrane fitted the right way round in the housing?
-
Sorry to raid this thread but at what tds reading do you guys change your 4040 membrane

There is something not quite right with Matty's setup.
This is the time to take every thing apart and start again.

What 4040 have to got? Champ or Vyair housing? How long have you had this 4040 and has it always been slow? If not, when did it change?
If you disconnect the hose from after the prefilters, do you have a good flow of water through the prefilters? Do the prefilters have 1/2" ports?
Is the 4040 membrane correctly inserted into the housing?
Install membrane into champ pressure vessel:
Remove the end cap from the feed end (the end with only one port) –
this is achieved by pulling on the white tab which will remove the white
holding ring. The end cap can now easily be removed. Remove the
membrane from its packaging. Insert the membrane into the housing
with the black brine seal at the feed end (ie feed the membrane in with
the brine seal end going in last). Push the membrane firmly to ensure it
is fully inserted. Push in the end cap, again ensure it is fully inserted to
reveal the holding ring groove. Replace the holding ring.
(The brine seal is the seal at the end of the membrane.

This web page should help. The 4040 membrane is the 4" one pictured left hand bottom corner.)
Are the connections fitted correctly? (On the champ housing you have one port on one end and two ports on the other. The end with the single port is the inlet from your prefilters. The other end is the pure and waste ports. The pure port is at the top in the center and the waste is on the side opposite the inlet.)
Here's fitting a 4040 membrane into a Vyair filter

Thanks to and others for suggestions, went round a mates last night he produces loads of water, tested my Hf5 and his Hf4 on his system, firstly with just the tap pressure which was about 50psi, his membrane produced a litre at 50/50 in 25 secs and 30tds, mine on same system just over a min for a litre 20tds, have borrowed his hf4 and a booster pump and will test it all on Sunday on my system, just to say the pump was amazing the way it boost the pump.
-
They say you should not need a booster pump on a hf5 but on a hf4 you do.

I know smurf, but we tested both last night on same system the flow on the hf4 was alot better, when i test both on sunday with and with out pump on my system that will tell me whats happening and i hear it's possible to have a faulty membrane
-
Just thought I would update what has happened with my 4040 system, after testing the other night at mates place (hf4 and hf5), tested at my place again, my mates hf4 was sound one litre in 2,0 secs with pump 9 secs, put my hf5, to cut along story short getting tds of 180 from pure, sick to death of it, my conclusion is the hf5 membrane is faulty in some way, it has taken days of testing but i just cant really figure it out, will send back to company to test it, mate says can borrow the hf4 for a week.
-
Hello Matty can you please tell me what sort of booster pump you are using ?
-
sorry mate not sure, borrowed of mate, it's green and made in italy, , he's had it years and lent it for a week until i sort situation out.
