Hi,
I was thinking of changing to a 4040 RO as i carnt stand the little 300GPD ro from purefreedom i dont run it over night either because its in my path and you can here the booster pump and my nabour is a postie so hes in bed early! so hopefully if i had a 4040 it would just needed to be run in the day all day to provide as much as am going to need.
i was thinking of doing this! if you can that is..

Buying one of those the top one proberly and the housing for it below

then for the pre filters was thinking of connecting my current Prefilters up on my 300 GPD ro!
Would that work? would you still get lots of water doing that or is best to get the prefilters that normaly come with that system.

probably a good idea to get some 20" pre filters as a 4040 is 2000gpd system so the old filters won't last 5 minutes.
If you do decide to get a 4040 make sure you change the filters when they need it or sooner. membranes don't come cheap and they will fail if you allow chlorine through them.
-
the filters will last as long as they do at the moment, your not making any more or less water, just making it quicker

If u have to boost the 300GPD u will have to do the same with a 40 inch set up and BOY do the pumps needed for a 40 incher make a noise. A whole lot more than a small system booster pump :o
-
Best thing to do is pay a small amount more and get one of the basic 4040 set ups from Gaps, you can't go to far wrong for that money!

how much noise ? I am thinking of getting one

I don't use a booster pump and it works spot on.

as do I but like the idea of making water quicker ;)

Takes about 3/4 hours to fill my tank! without, how long would it take pumped?

that would depend on what size tank you have, I have 650l about 4.5 hours to fill, but pressure seems to have dropped a bit.

Then ur water pressure must be decent.
ALL Ros are dependent on water pressuref or output and TDS reduction. Basically the better the pressure the better the output/TDS reduction.
A 40 inch WILL work @ 40 PSI but not very well at all. The same does for the smaller systems.
Ian.. it's a LOT of noise mate. It needs to be mains powered to do the job properly. 1 to 2 Horse power ones are pretty normal for boosting 40 inch systems.

I do have very good pressure just high TDS which is a nuisance!!

Same as, it does my head in big time, my bills are stupid, i might try and tap into the mains :o

don't buy the plastic housings, go for the stainless steel, only a few quid more and boy o boy is it worth the extra.

What difference does it make out of interest?
-
no difference to water production but :-
looks sooooo much nicer (all lovely and shiny)
much stronger than plastic housings - if it gets hit or dropped it ain't going to break.
about £30 more I think.

Good point, the frost will probably not crack them either like it did to mine :( when i forgot to insulate them earlier in the year!
-
sean - have you left Brodex? Whats the story?
-
Frost will crack open a stainless housing as easily as a plastic one; moral of the story, all membranes have to be protected from frost, irrespective of the housing material.
more so if it is metal as metal freezes quicker than plastic ;) may look nice (point not many see it)

Leccy and gas bills are stupidly high too, have you tapped into those too :o

the housings are 304 stainless steel - they will only crack if the entire body of water in he housing freezes along with the membrane, thats only going to happen if the unit is left outside in siberia type temperatures.
the plastic housings will crack long before the stainless steel.
anyway you shouldn't let your ro unit come near to freezing. ever.

my 300GPD is useless at the moment even when boosted it still only makes 27 29 litres an hour at 85psi 40psi before boosterd.
is there anyway you can deadin the sound of the pumps? sort of put it into a box with something to try and lower the noise..
my idea was just to run this in the day because of the noise which is what i do now with the 300GPD but running say from 9am to 6pm would only make about 240 literes :-\ were as i was hoping the 4040 would be more enuf just to be run in the daytime.

Iv just looked at one of my old posts and Easy is using the same booster pump as me for his 4040 RO system .. so maybe it can be used proberly not the best to use but if must work
here is the post
