Very nice Chris I love the wall paper!

[Sir Patrick]

Nice Chris! I think I am going to the it the spectrapure 90gpd.

I use a 10year old RoUltratec 100gpd system with an add on DI unit for one and a 5 year old ebay 100gpd Water General with a DI add on. Both have been fitted with Spectrapure's silica busting membranes so they've been reduced to 75gpd. My Roultratec also supplies my refridgerator's water/ice upstairs before the DI.

Mine was also originally a 100gpd, but reduced it down to the better 75 gpd rejection rate, a few years latter, after I found out about it.

I got this one from Filterdirect.com in California for $160.

It has the reservoir tank that keeps the system pressurized and even pushed RO clean water to a faucet upstairs and the icemaker. RO ice is worth it in the long haul IMO, but it'll fill your ATO reservoir a lot quicker if you ever run too much out of your drain.

Nice setup.

Spectrapure 90gpd Maxcap RODI

Plus
Membranes are tested at 98%
Inital sediment is 1 micron
Comes loaded with 2 DI canisters
all the goodies (gage, TDS meters, clear canisters)

Negatives
98% membranes can only come from Spectrapure (as far as I know)
Restictor needed to be trimmed and unit tested to bring unit to operating spec when new.
Ordering any parts from Spectrapure takes for ever to ship for some reason..I call them "slowpokepure".

I purchased this unit new and added a Aquatec 8800 booster pump kit and a flush valve. Its been a great unit with wonderful customer service from Spectrapure to boot in the last 4yrs.

Thanks Todd. That's the same unit im looking at.

I use a BRS 75 GPD 6 stage fitted with a boost pump. The 100 PSI working pressure allows the RO to produce ~1 TDS water into the DI.




I did add another pressure meter on the water supply side. I also purchased Spectrapure MaxCap and SilcaBuster DI resins as I'm told they are far superior. Haven't had a chance to test them yet.
