After using our little 300gpd for the last few years, we have ammassed more work and we've finally opted for the 4040 system from Phil at vyair. I have a water pressure of 45psi and the new system is running flawlessly without a booster pump and a low pressure membrane. Getting about 90 litres per hour at the mo. Could introduce a pump, but the production is enough for us at the moment. Well pleased with it, and great customer service from vyair. TDS into Resin is about 9 and 000 pure into tank. Onwards and upwards ................Just need another van now, thats a cue for another post

Is that in the van or static?

Static Rob 

[johnny bravo]

what was the price of your 4040,   how big a DI vessel do you use
cheers

[Fieldsy]

Hi,

Vessel is 8 litres (which I already had from the small system )

4040 was £518, that includes stainless steel casing, low pressure membrane, 3 x pre filters with carbon wrap filters, all connections/connectors/ptfe tape.
Membrane was pre-installed for me by vyair.
8 litres of resin.

All I had to get was 30m of reinforced 1/2" hosing and a sheet of ply to strap it all to

Well pleased

Well done, and as you say when needed you can increase production by adding a booster pump

If you add a booster pump wouldn't you have to change the membrane ?

[Smudger]

Don't think so,

Even the ultra low pressure membranes run best at 80 psi according to the specs I've read. - they can run on lower ie. The 45 psi the op is running, just not optimum

Things like the the hf5needs around 110 psi - it does vary from make to make.

Well, Vyair sent me a booster pump as well, and told me I could send it back if not needed, so I'm assuming it would have been ok to use it

[Clever Forum Name]

I would be interested to see what results i can achieve with a booster. Tap pressure of 70 - 90 psi

Good to know, i am moving areas so will check water pressure when i get there

[Fieldsy]

Thats why I posted, just to let people know, water production is feasible with 45psi and without a pump. As Smudger said, I can always add a pump if we need even more

[johnny bravo]

ill have to check my tap pressure, keep meaning to get a pressure gauge

[johnny bravo]

if you have any pics of set-up can you send me some to my email,   this may be something i can fit in outhouse, ill have to look into set-up space etc.,
what takes me 8 hours for 220 litres could be done in just over 2 hours.     i could get enough done in 1 day for what i need.

[Fieldsy]

@ Johnny, speak to Phil at vyair, they will send you one free of charge to test your pressure, as long as you send it back  and yes I'll take some pics for you,

cheers

[Fieldsy]

Heres one of the set up and the 2nd one to show size in respect to the 1000 litre tank

Nice job ,

[Fieldsy]

Thanks, I try  ...lol

Thanks, I try  ...lol

hi mate what is your tap tds going into the system before you achieve 9tds?

[Fieldsy]

Hi,  mains is 375

[Avo]

That's really good 👍
