Hello,
2 years ago I bought this RO unit;
http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=190450639900
My question is this, when I purchased the 50gpd unit 2 years ago, I was getting a ph of 6.4. Then last year after I replaced the filters according to the 1 year cycle, my ph climbed a bit to 6.8. I upgraded the unit to a 150gpd last May (which for some reason I do not get) and the ph stayed at 6.8. Over the last 3 months, the ph has been above 7.4. Now, nothing changed except the output. I changed filters regularly.
Can anyone tell me why this is happening possibly? My tap water ph has not changed, it's still 7.4/7.5. After installling the new filters and running 5 gallons through the system today, my ph is still over 7.4.
When I upgraded the unit to 150gpd I was averaging maybe 100gpd ( I am sure water pressure changes the outcome) after changing the membrane and flow restrictor. But that should not effect the ph.
Thank you,
Jeff
