300 gpd should not be meationed in the same breath as a 4040

300gpd is slow at providing water, 4040 kicks it out add a booster pump to the 4040 and you would not be able to use the water it makes fast enough, where a 300gpd with booster is still slower than a 4040 on a standard tap, this is what I have found, I started with a 4040 and now have 2, I bought 300gpd and merlin to see the difference so I can learn and educate others 

Go for a 4040

Thanks for your reply....anymore for anymore?


Without a pump I have around 50-50 water pressure. So how much water could I look at creating say at 7 deg.

In the mean time, shall move over to the ro-man site and look for some answers.

Cheers Dave.

On a good day a 4 x 40 will kick out about 250 - 300 lts an hour with a booster pump. My water in is around 325ppm water out is around 004ppm.
On a cold day this will drop a bit but 200lts an hour is still pretty quick.

with a booster pump I have had 8l pm and my tds is 470+ I guess it depends on the pump you get, on tap pressure its about 4.5 hours for 650 in tank though di so pure

[pingu]

Sorry Windowwashers I did not mean to brush you off or give that impression...sorry

Dennis are your output figures reduced in the colder days?

I originally bought a 100gpd system from Andrew McCann (top bloke) in 06 and upgraded until it is now a 300gpd...but have experiance these cold days...and having had my outside storage froze so much that it is still frozen with my transfer pump still encased in it...I would like a way of producing water and quickly when I need to...and I just do not want to have to dedicate so much space to water storage.

Cheers

I want the idiots guide like pingu.

i know what a 100 200 and 300 gpd are, but whats a merlin, a 4040, and what I have a 40' ro. can anyone tell us in simple terms?

[pingu]

Oh yes...simple please and small words would be a bonus

explain what you want to know and I will tell you what I knwo about it, I have had all of them , Clive you have a 4040 now

[Clive McDonald]

Okay so mines a 4040 this has three pre filters and a 40' bazooka thing, so what's a merlin then ?

[pingu]

So really a 4040 is just the name or type of membrane. Looking at Gaps website they say "Production will vary according to water pressure and temperature (typical production rates are from 80 to 200 litres per hour). Typical rejection is 98%."

So this would seem to be an ideal solution to stop having loads of water sta around in storage and taking up room.

Question:

Do you really need a 8litre ++++ vessel for resin or could I just keep my 750ml one that came with my 100gpd system...?

[Clive McDonald]

Mine (4040)cost £523 inc vat.
i believe a 300gpd is towards £300
basic booster pump £80, good one £300.

I ran my good pump outdoors for 18 months and broke it. I had an electical problem on the cheap one. Leaving electrical stuff on overnight or when i was out working was always a worry.

As mr oakley said, i had pipes blow off a few times.

[pingu]

When you say booster pump would you mean something like this?

[Clive McDonald]

There are a few matts.

there aren't any booster pumps there's a world shortage. That's what i phoned up for and arkwright sold me the 4040 instead.

thanks for the pic. There are four connections inlet, pure, waste, and.....?

[pingu]

Does anyone use the h5-4040 Ultratec that is for sub 50psi water pressure (no pump required) and what do you think of this and what would you say is your rejection/waste rate ?

Cheers
Dave.

[Oakley Windows]

These are still available, this is what I got yesterday.

[Clive McDonald]

Thats the exact one i had.

not much on pressure pingu but if you have a meter on your 300 as i do.


mains with no pump halfway into the yellow.

Pump in picture into blue

good pump into red.


There were differences in production times. With this 4040 thing water gushes out just off mains.
