That just don't make sense! I'd say your RO
membrane is bad. Is there any way to sample water before the DI
but after the RO
? Got a "drinking water" spigot on your unit? If so, then compare your post-RO
number to your pre-RO
obviously should be lower. If not, then there's your problem. And if your post-DI
number is higher than your pre-DI
number, then your DI
resin is shot and is leaching stuff back into the water.
Even running tap water through a DI
resin by itself, with no RO
, I'd expect you to get more than 10 gallons... but then again maybe you're water is particularly nasty right now. I run a dual cannister DI
unit off of a Kold-Steril unit (no RO
) and get between 50 and 80 gallons per resin charge.
With the wet winter we've had, you could be seeing a spike in the phosphates in the well water due to excess surface runoff. Just grasping at straws...
