Just wonmdering about anyone that has a 4040 what the tds in and tds out is also pressure if you know?
-
Hi Ian
My tds is around 350-400 in
I use a booster pump which puts pressure up to 5-6 bar?
tds out around 10-12

In some cases with good water pressure you will get the water down to 002 after RO and your resin will last ages.

tell me what you have NHW please if you use a 4040 that is.
Russ cheers for that ;)

TDS in 240 out about 8 it was lower out at one point though so the filters probably need changing pressure is about 100 psi pumped from a 24/7 pump but without the pump on pressure is about 35 psi with the tds still at about 8.

you have a 4040 on 24/7 christ you must use a load of water per day :o

2 pre filters and a 40x40 is the ideal setupyou should flush the RO 5 minutes prior to filling,Gaps water do the perfect setup for window cleaners if you look on there site.About £550 will get you more water than you`ll use,there`s someone on here trying to sell water for £30 per 1000ltrs 20 fills from this setup and it`ll pay for itself at the ridiculous rate he`s selling it at.

100psi booster pump will help you make water a lot quicker,or a 150psi.

I have 2 4040's,.
anyone reading this a surflow 100psi pump is not what you need.
nwh i was asking if you have a 4040 if you do what is your input tds and output m8, I just want to see if mine is abaout right or not ;)
the guy selling water if I needed it straight away I would pay £30 without even thinging about it as a van down for a van would cost me a lot more than that.
-
Water in about 280-290,water out 002-004.

what is the waste on that compared to pure % ?
-
Regardless of what they tell you it will be 50x50 at least but i think the waste is a lot higher than that,if you increase the waste the quality after RO will be better.If you look at the waste pipe when filling ther`s a lot more going down the drain than going in the tank.

I do it the other way myself
-
What i meant to say was if you fill slower the quality will be better,if you fill quicker with less waste the water after RO will not be as good.

I understand that m8, I just wanted to know what every one else is getting and is it worth me joinging the 2 4040's together :-\
I go for speed because of time, I know it costs a little extra in resin but I am limited on time so is worth the extra cost be it minimal
-
If need to make water quickly i would go straight for the industrial unit they do for about 3k,twin RO with 20" pre filters and auto flush.

sorry I ment a 24/7 rated pump but I think you know that ;)

was unsure to be honest, I speak to loads of people and some that I speak to personally shock me in what they have going on, so I did not know m8 ;)

Mine is exactly the same with a 50/50 pure ratio

TDS in approx 300.
TDS out approx 018.
(I don't really know why I've never been able to get it lower, I've adjusted the waste ratio every which way).
I also use a booster pump as my water pressure is useless and Water Authority won't let me turn it up.
Water pressure when filtering: 80 - 85 psi.

I know GAPS do sell a HF5-4040 membrane which is designed for 50psi and lower pressures...do not needing a pump.
I am trying to get one but they will not be any available until around mid-feb.
Cheers
Dave.
ps while we are here anyone recomend a particular 12v solenoid cutoff valve?
-
TDS in 543
TDS out Approx 20
-
In 300 out 6. Straight from my outside tap.
-
300 in, 7 out. Booster pump 75psi. Fills two 1000lt tanks in 7 hours
-
250 in 4-6 out 4 bar no pump, hf5 membrane, fill a 650 ltr tank in approx 3 hrs, 50/50 ratio
-
about 400 - 430 in and around 18 - 20 out!
thats with alot of waste to pure :'( as advised by gaps because we have rly bad pressure and flow! which my pump brings pressure up but there just is not enough water flow so they said.

If you risk running out of water why not get a bigger IBC. Mine is 1500 litres and I have seen one 2000 litres from Stream.

i got twin 40/40 from gaps with the hf5 membrane from the usa very good 400 going in 8 out. fills my 1000 l ibs tank in 3 hrs i got a bypass fitted on to the waste so about a 1/4 goes back through the system to cut down on the water bill.

what is your waste roughly, before the bypass ?
