I bought a used BRS 6 stage RO/DI system in June 2018.
I bought a BRS 6 stage replacement filter kit around xmas, it's still in the bag.
Just dawned on me that kit doesn't come with membranes, my system has 2 membranes.
So from what I have gathered through search feature here on R2R I've found that if they go unused and dry out I need to replace them correct?
So I took the cap off of the top membrane to pull it out to see which one to replace it with and to my surprise it's still wet, has water in it so I left it for now.
Can I get by making my first 100 gallons or so of RO/DI without replacing these membranes?
I believe them to last be used with pressure in April of 2018.
Lastly is there any reason not to upgrade to higher output membranes when I get new ones?
I ask because the dow filmtec 100gpd (same part# as BRS) from amazon are cheaper than the 75gpd from BRS. There's only $4 difference on amazon between the 75 and 100gpd membranes.
I realize if I do upgrade to 100gpod membranes I will need to change the flow valve. Is it worth it?
Extra info; I have 50gal tank my daughter has 20gal may turn into 40gal tank. Plan is to do 20-25 gallons per week water changes between the 2 tanks together along with approx 14 gallons per week of evap. to replace. So maybe 35-40 gallons per week sound right? Is upgrading necessary in my case? Would you upgrade? Did you upgrade yours please explain.
Thank you all for your input
