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

which pump you go for in the end

[Jimmy Jon]

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  , 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?

[groundhog]

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???

[Lee GLS]

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 

[David Kent @ KentKleen]

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

[Topclean]

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.

[dave0123]

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 would rather buy 30 b&q pumps

they phasing out that £30 one so you cant get it anymore

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) 

[Nameless Drudge]

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?
