RO Unit Question

[RayAllen]

Today I changed my filters on my RO Unit- LONG LONG OVER DUE

I changed all three filters and the RO Membrane.

All the filters have a specified 6 month life span, but the RO membrane does not list the longivity.

What is the life span of a RO Membrane?

Note: Im going to ad a DI canister to my RO system soon.

i was told the membrane will last 3-5 years IF the other filters are kept up with which means your TDS doesnt ever get high

I thought it was 2 years

[Gseclipse02]

you could be right its been a whiole since i was looking RODI stuff up

[Gseclipse02]

your right

"Membranes can function well for a year, two years, or more"

Cool, good to know. I told my wife to help me remind me to buy filters every six months because we also use it for drinking/cooking water. She will be happy that I dont have to replace the membrane for at least 2yrs. The membrane cost me $50 by itself today. The other filters ranged in price from $12-$22.

I do have another question what is the typical gallons a RO or RO/DI will make in a day if allowed to run. It takes mine forever just to make 5gallons.

[Gseclipse02]

So many variables but I make about 5 in 1 hour 20 mins …

Takes me about 3 hrs to make five gallons. Going a lil faster now that it is hot out. During the winter I only have drips if left running. Right now its a steady stream. Mine is a 25gallon per day.

Cool! Took me over a hour for 5 gallons as well so I guess im on track!

Ive had this RO unit installed in the house for 3 yrs but its really only been used for drinking and cooking with the occassional gallon or two top off on the nano. Not so much for water changes so thats why after all this time im asking these questions. Really just tired of buying water from the store, so I thought its time to take advantage of having what I already have and change the membrane and filters.

Tonight i have figured out when I want to do a water change its best to get the water started days in advance just so that I have enough, lol.
