Brandon,

You definitely should come by! Vancouver is nice, but mostly because it's near Portland. :D Kalifornia is nice but having lived there most of my life I got a bit tired of the political climate. brrrr.

Where do your future Grandparents-in-laws live? That's an insane phrase BTW...and I am NOT old! I am only 40 for Pete's sake! Of course, to you, that's the "Old Guy at the end of the Bar"! :lol:

It's always great to meet other reefers and trade info., frags, etc.

You won't have to make too many cultural adjustments other than the surprise feeling you will get when someone will let you in their lane ahead of them. And of course, like what happened to me a couple of days ago when I nearly turned a bald eagle into a hood ornament. Damn bird was sitting on the edge of the road gully hunting!
 
well let me rephrase the statement because i think I said it wrong. they are my fiance's grandparents, so my future in laws. They live in Port Orchard.

Old? Nope, my dad is 56 and my mom is 46, so old to me is pushin 70 or 80. I just know that my 22 year old back is in better shape than most of the 40 year old backs out there :rollface:
mostly just because at 22 we still think that our backs will never fall apart or wear out. :rolleyes:

This statement cracks me up. Jonathan, here's a young whipper-snapper that will help you with your spelling. ROTFLMAO!

tedious

;) Just teasing you a little here...
 
LOL...computers have dumbed down the population. With spell-check, you cannot expect anything better out of a collage student these days. :D
 
Atleast most college students don't have to poke at keys like a chicken and actually know the correct "way"to type without having to look down for every letter... :D

Just a little back pickin even though I'm not in college anymore

RO/DI progress is really slow. The primary problem appears to be pressure. I am only getting about 20 lbs. on the Kent gauge and I think that is about half of what it really needs. Not sure what I can do about it. If I take one of the units offline, the pressure goes up to about 30, but output volume drops. The water is processing warm so incoming temp. is not the problem. I know that my other RO/DI unit upstairs only gets about 45 psi, but that's enough and downstairs pressure IME is actually higher. I would hate to have to get a pump. Anyone have any other ideas?
 
Try opening the valve at the connection to your water supply line. Your production should not be large enough to cause that kind of pressure drop.
 
I did try that of course, but no difference moving to various positions. I had a buddy over today that said because I am splitting the water supply, the pressure is dropping in half, but I am not sure I agree with that assessment.

He also felt after looking at the whole setup that there must be some pressure variations happening outside the house. We experimented with directing water different ways but could not get good flow and pressure at the same time.
 
You want 80psi actually. 40 is common in our homes. Some guys on our club's message board found one on Ebay for $85 but I don't know if they ever received it. Typically they run more like $185 for a 100gpd unit. You might check Filtersdirect.com to see what they cost.

A booster pump will increase production rates, and your membrane will pull out more crap than it will at lower PSI. With a 1000g system, it seems like a good idea to have faster water production.
 
Couple questions: will a booster really help the membrane pull out more stuff? I thought that the faster it feeds, the lower the water quality...

Also, filtersdirect.com is gone. I checked with filterdirect on ebay but they don't have any booster pumps. I have one on my other system, but it is not really a booster pump. It's a device that relieves back pressure associated with filling a bladder tank.
 
At the water flow rates we are dealing with in RO/DI production, I have a hard time believing that splitting the water supply is dropping the pressure by half.

What is the static water pressure?
 
Membranes work better at higher pressure. I've never tested this out myself because I don't need a booster pump for my unit. I'm going off what I've been told repeatedly. I know that some that use booster pumps get 0-2 TDS out of the RO!! and the DI ends up lasting much longer as it has pretty much nothing to remove.
 
http://www.pwgazette.com/6800pump.htm - Get the 8800 this is the best online price I've seen for the whole kit. My household pressure is 45psi with the 8800 I get 110psi on a 100gpd unit. I crank out about 120gpd. Not to mention your RODI is more efficient at the higher pressure. You get a better product to waste ratio a real 1:4. I love my booster its one of the best investments I've made. I get 1 TDS out of my RO and 0 out of my dual stage DI.

You can also pick up a Permeate Pump that will do the following :

Saves up to 85% of the water that normaly goes to drain line. Requires no electricity - pump powered by energy from brine normally lost to the drain.

Improves water quality
Saves 400% of waste water vs. conventional units
Increases membrane life
Prevents "membrane tds creep"

I have had my Permeate Pump for a few months now and I think I may pick up a Booster Pump as well... I didn't at first because I get about 65psi, but I think I might pick one up...
 
Static pressure is only about 42.

Thanks you so much for your responses!

skatezen maybe you can give me some advice. the link you posted is great but there is more than one way to hook that pump up using pressure switches and electronic switches. I am not going into a tank as their specs. indicate and my supply line is split to two units. from these units pure water goes out to holding tank, top-off for QT, 7 display. Which pressure switch should I get do I get and how would it be installed?
 
Shawn,

The permeate pump is only for use on systems that encounter back pressure from a bladder tank. It doesn't offer any advantage on free-flowing systems based on it's specs.

I am using one and its working fine with out a bladder (pressure) tank... I am kinda mad because she told me it may or may not work with out a bladder tank so I ended up buying the bladder tank along with the permeate pump and I set it up with out the extra tank to see if it would work and it does... I know its working because you can hear it clicking on and off and I can watch the waste line stop producing water were as before it was a steady steam...
