How long to make rodi

[Clown79]

How long does it take for you to fill a 5g bucket?

[REEFERzz24]

depends on the system you have and your water pressure but for me about 45 minute

[Dougefresh35]

Sorry man cant answer that one I fill a 50gal brute and it takes all night long its all full when I wake up

[Thrassian Atoll]

Couple of hours.  My pressure is 40.

[Clown79]

Lol. So it's different for everyone.

 

My psi is 60. It's been 30 mins and I have about a gallon.

It's like watching water boil.lol

BRS 5 stage RO/DI with Aquatec booster pump. My pressure is around 85 with a booster - make 5 gallons in about 35 minutes

Tilton have you ever looked into a booster pump you definitely get a better return with more pressure 

Ya my psi runs almost 70 no booster

I have not.  I need to look into it.  Not sure why it's so low.  Water is always warm here in Phoenix.

About 45 min.  45psi  BRS 4 stage.

Oh boyyyy! He’s back!!!

 

every RODI system has a rating. I have a 75gpd unit. So 75 gallons in 24h. About 3 gallons an hour. So a gallon every 20 minutes. 

 

Look at your unit. If you run it at proper pressure you’ll get that GPD. You run it loader it’ll be slower.

Don't know what my pressure is but mine is about the same. 30 min per gallon. I just set a timer and walk away to do other things. I try to always have 2 gallons ready to go.

I was just surprised at the slow trickle but it's coming along.

He is a she and I was curious to know what everyone else's experience was...isn't that the point of the forum?

Not whining....the "oh boy he's back"

 

Makes one think maybe asking questions is a bad thing?

Wonder why yours is that much faster than mine with the same unit and almost the same pressure?  Could I have too much waste water?  Might have to check that again.

 

I am guessing it also depends on how dirty the water is being filtered right?  The higher the tds the longer is takes?

Makes the boy who comes back or the boy who lived? #Potter

 

 I don’t think asking questions is a bad thing. I think asking questions that could get a straightforward, easily comprehensible answer on google may be a bad thing. Not saying that your question was a bad thing. Or a googleable thing.  What light is on the 10g?

It's the same with every forum and every Facebook page.  The same questions get repeated over and over or there's simple answers on google.  The thing is though, some of the stuff gets burried on the page or this and that.  It helps spark conversation and helps newer people who may have the same question.  

 

Some stuff on some pages get beat to death though.  I usually just move along though and don't bother.  It's either read this or read one of the 476 pico threads right now.

30 minutes for 1 gallon sounds pretty slow to me. I have a 5 stage Spectrapure and I'm getting 3+ gallons every hour at 40-45 PSI.

Well I haven't actually put a timer on it. That was a guess-timate. It may actually take an hour but it's in that range. It set it up and then go back to check it and it's pretty full (but not overflowing) in that amount of time. 

 

Not sure if how dirty the water is has anything to with it. My unit is still really new so maybe that Is a factor - like the water passes through the filters more easily. 

I'm definitely not a RODI expert!!

I have the Marine Depot 4-stage. My 30 psi pressure was way too low to operate the membrane correctly so I had to get a booster pump.

I have the 100GPD unit at 80 PSI and it'll take me about 50 minutes to fill a 5 gallon bucket.

[SaltyBuddha]

My RODI 4 stage from Marine Depot used to put out 5 gallons in about an hour. Now it is going at about an hour and a half or a little more. Doesn't matter to me as long as I still have 0 TDS.

When I have a house I want to set up a larger brute system. But don't think I can get away with that in a 1 bedroom apartment lol 

[holy carp]

Patience is a virtue.  The slower your RODI, the more virtuous you are...

 

Seriously, though, it depends not only on the water pressure and the RODI system, but the quality and condition of the filters makes a big difference.  Speed is nice, but 0TDS is the goal.  I have a 5 stage Spectrapure with a 0.2um sediment cartridge and a booster pump.  When it was new a 5 gallon bucket filled in about 45-50 minutes.  Now it takes an hour or 70 minutes.  The sediment clogging makes a big difference, but as long as you get enough pressure at the membrane, it's still fine.  With the booster I get about 85psi.  Without the booster almost all the water goes out the waste line.

Lol. I'm in an apartment too. No place for large containers.

 

My psi is 60.

Now tds going in is 513 (highest reading)?

Going out 0. 

Did about 7.5 G in 2.5hrs.

 

 

I didn't care really how long it took. Was rather curious to see others experiences. 

[SaltyBuddha]

513 is pretty high. I think mine was around 350 when I first tried it out. Surprisingly, a Brita filter gets it down to 45 (and that is a really old filter!)

[Clown79]

It's the highest I have seen listed in the major cities here. It's river and well water. Hard too.

 

I don't drink it anymore.
