R/O units
 

Like to see what other are getting as far a gph or gpd. I hooked mind up yesterday and in 17hrs I got 11gals is this normal. My line pressure is 55psi.

How many GPD is your R/O unit rated for? Also, what is the temperature of the water? The colder the water, the less R/O you get in my experience.

Hi Harvey its a Aqua-safe 100 GPD ("RO+DI") SYSTEM 6 stage. I'am not sure of the water temperature will check that tonight, would you suggest mixing my source water with both hot and cold?

BAD!!! No, that's a really easy way to kill your membrane. From what I've read, you can get 25 feet of the same tubing that connects from the water source to the in of the filter, coil it up and submerse it in a bucket that has a small heater in it keeping the water @ 78°f. That will help boost your production.

coil the cold ro tube and leave it in the sump...instant chiller

Just curious, why would warm tap water kill your membrane but warmed water through a coil would not?

I think Dan is implying that there is more room for error (i.e. accidentally running only hot water to the unit) when hooking it up to the hot water line and killing your membrane.

you may also want to check the PSI the unit requires.

Also double check your connections and filters.

I've got a fairly new 100 gpd unit from Aquasafe and all I get is 30-35 gpd. Took forever to fill my tank initially. The 100 gpd is a myth to sell the unit IMO, unless someone else out there has made the unit go into top gear, I would like to know how. Just my 2 cents worth.

i have an older marine depot 4 stage unit. it can fill my 30 gallon brute can in around 5-6 hours. when the carbon prefilter is shot it takes around a week to fill the container.
