About 2 years ago I got tired of lugging jugs of water home so I bought an R/O and think it's great but I'm wondering if I should change the carbon block or TFC membrane yet? The manual (a xeroxed sheet) said when the flow of good water is reduced it needs replacement but I can still make a 5 gallon pail in about 2.5 hours which is what it has always produced since I got it.
I've done the math and on average I make 20 gallons per week for 104 weeks is only 2080 gallons. Is it time to change anything or can I chill?
BTW my water at last testing some time ago) was a PH of 7.4 out of tap but has a high carbonate hardness due to the apartments sodium softening... if that matters in judging replacement.
Thanks for any thoughts! *[img]http://www.**********.com/iB_html312/non-cgi/emoticons/smile.gif[/img]
