I got myself a booster pump for my 4040 as I am moving soon and will need one, but I decided to rig it up today to test it.
My tap psi is 80 but after the pre filters the pressure guage says 40, and it takes about 3-4 hours to make 500l.
Put the pump on and the pressure guage after prefilters was reading 85 psi, and it only to 1h 20mins to make 500l.
The tap tds is 375 and now it comes out of the ro at 8ppm.
Altogether a happy chappy ;D

which pump you go for in the end
-
Well done Lee exactly same scenario as me - low water pressure, hard water high TDS reading 360+ ppmcomes out of ro at 008ppm.

I am using one of these at the moment.

I know its not classed as a booster pump, but it is a continual rated pump, i got it as a transfer pump because it will pump 81L a minute, so i will fill my tank in 7 minutes ;D, but i thought i would try it as a booster pump and it works fine. I will have to end up getting another pump anyway as i will need a booster pump and a transfer pump, but it works just the same as a booster pump anyway. ;)

i use the Clarke booster pump with the electronic thing on top

what pump have you got terry?
-
I have a booster pump on my ro, I've had it on there for at least 5 years and it still works great!! But I'm still not producing water at that sort of speed!! I might have to check out one of these 4040 ro's, as it looks like I'm going to be on a water meter quite soon!! :(

Hi Lee, I have got a Clarke CPE100TF booster pump which you can also get from machine mart or e-bay
-
DO THESE SAVE ON WATER USE???
-
Depends on how much you have the waste tap open, i could now shut my tap more, so I will produce less waste, and the tds will be the same as it would be with out the pump and the tap open more (producing more waste).

richy u dont need a pump old bean ;D ;D

i use a £10 b and q pump and get the same results ;D

after many trials and variations i have now gone down kent clean route, many thanks to kent clean and help from lee cheers.
As far as these clarke pumps go with the tank underneath i was told by june from gaps that these were not good for your membranes as i have gone through a few in a very short period of time, i decided to change things around.
with in 6 months of using one of these pumps i killed my first membrane hf4, reported to june she then told me that these pumps were no good, because the pressure builds up then releases a high flow, (well thats what mine was doing anyway!!). then i ordered a hf5 low pressure membrane, with in 8 months of using this with out a pump this membrane was nackered. (meaning the tds started at 11tds then i couldnt get any better than 60-70tds).
Now i think my problems might of been down to the fact that my pump and ro were about 40ft away from the mains, so using 1/2 inch hose to the system and then again using 1/2 inch hose to the waste. (think i might have been losing even more pressure using this hose)
Today my set up is in my yard and is set up as follows: 22mm polypipe to £10.00 b and q pump, 22mm pipe to pressure gage, 15mm pipe to pre-filters, then double 40/40 ro to di then to holding tanks all with polypipe and push fit fittings. my system now produces a combined tds of 11-12tds before di. I can fill a 1000ltr tank in about 2-3 hours. this is housed with in a few yards of the mains. P.S. 350-400tds going in.
I personally think that using polyfit pipes and connections has to be the only way. (no loss in pressure).
Hope this info helps, as it has cost me a fortune to get right!! TIME WILL TELL.
-
This was the one i was recommended by June at GAPS water and a few people on here few years ago! works great. I also have quite a fun from the mains of 15mm hose you do loose a slight bit of pressure

I havnt botheres with the pump with the tank.
I originally got this pump http://www.machinemart.co.uk/shop/product/details/cpe130ss-1in-stainless-steel-water-pump/path/booster-centrifugal-pumps
i got it to use as a transfer pump and paid £50 off ebay for it, its practically new. its pretty much like the b&q pump but alot more robust and more powerful, but after reading kentkleens bit about using the bq pump i thought i would connect it up and give it a go and the results were excellent.
But as i need a booster pump and a transfer pump i have just ordered this http://www.machinemart.co.uk/shop/product/details/cbm240-1in-multi-stage-water-pump/path/booster-centrifugal-pumps
i got it for £163 inc delivery from ecosure, its max pressure is 120psi, so it should last for years and produce even better results than the pump i have now.

That’s the one we have got and its been great for past 2 years, no problem. As they say (YOU GET WHAT YOU PAID FOR) :)
-
Lee, i have a 4040 set up and the pressure drop from the pre-filters is only 4psi. I have appx. 50 psi going in and 46 psi after the 2 pre filters. As the water pressure varies a bit the 4 psi drop seems to be constant.The filters are 10 inch.Just thought i`d mention this as the pressure drop you have seems a bit excessive.
At this pressure the hf5 chucks out 007 from 300 in and i am well pleased with that.
-
What pump is this b&q one? Any links or any pumps available with similar spec?
-
Is it worth using a booster pump if you are di only , as my tap isnt that fast and 500 l probably takes best part of half hour, would a booster fill it alot quicker?
And when the valve shuts off at full would the booster pump stop??
-
i dont know how the pumps work with di only, but you would need a pump with a pressure sensor to cut the pump off when the valve shuts,

Di resin needs a certain amount of contact time with the water, so you do not want to pump it through.

Hi Lee,
Where did you get your 40-40 ro system from. I am looking to get a RO system and keep getting conflicting advice. Not sure whether to get a 40-40 or a 450gpd system. I get advice that a 450gpd system would be best as the waste to pure ratio is better and it produces a better tds reading at output and then I get told that they take ages to produce water...geting very confused!Maybe a 40-40 is better?
-
hedgehog, my 4040 system was part of the van mount that i got from the cleaning warehouse.
I havnt had a 450gdp system so i cant comment on what they are like.
when i was looking for a system, the info that i found was that the 4040 produce less waste than other ro's. I also caan imagine that a 450gpd would get the tds any lower than a 4040, after all my tds is high (375), and after the ro it brings it down to 10 without a booster pump, or 6 with the booster pump.
my 4040 takes 3-4 hours to produce 600L without a booster pump and today it make 600L in 1.5 hours, but either way the 450gdp will take alot longer than that.
Really it all comes down to money, and how quick you need to produce the water, i got the 4040 as i had nowhere to have a static system so i needed to be able to produce the water quickly.
If you have a static system, then the 450 would be fine, but i have been well impressed with my 4040 but they are £££

Cheers,
Is this the sort of thing you have http://www.gapswater.co.uk/acatalog/copy_of_Reverse_osmosis_kits.html
-
yeah, mine has the 20" prefilters.
-
Ok cool......So even without a pump you were getting good results
-
Lee, Do you know approx what the waste to pure ratio is?
-
to get the optimum tds, without the pump it was 30/70, but that can be reduced by shutting the waste tap more, but that increases the tds. i will have to see ifs its any different with the pump.
Are you on a water meter?

Yep..
So for ever 100litres 30 would be pure and 70 waste
-
right i have just done a quick test.
To make 1/2ltr (500ml) pure it produce 600ml waste, so that is 45/55 pure/waste ratio, that is with the booster pump, and the waste tap open slightly. do with the tap shut, im sure it would be 50/50 if not better and the tds would be 9.

Top man..Thanks for all that. Back to my original plan then of a 40-40...Cheers :) :)

Hi Lee,
Got my 4040 from Gaps today. Set it up. Sorted out a few leaks and very happy so far.
Early days but 50-60psi. 450 tds in ( :o didnt realise it had gone so high) output 30, then 22 now 17 tds. Approx 2 litres a minute pure at 1:2 max ratio.
Will play around with it a little more over the weekend.
Does it matter if the RO Membrane is positioned vertical or horizontal?
Cheers for your help. :)
-
No I don't think it does matter, but if you have it vertically I would have the waste tap at the top, those figures sound good as you have a tds.
Also as they are new membranes they will probably need flushing for an hour or so.

ok cheers.
my tds has gone really high... was 350 in the winter.
Happy with speed of water production and hopefully output tds will drop a little more.
