hahahaha Did you really need to ASK if your TDS meter was working?
My TDS surges to at least 200 or more when I start up a RO/DI fill. Craziness.
On a somewhat related question .. what kind of TDS are Calgarians pulling AFTER their RO? I bought a new membrane recently and it rarely reads under 5. I'm going through DI resin like crazy as a result. My last one seemed to register 0 or 1 way more often and I'm wondering what's more normal. I'm kind of thinking I got a dud membrane or maybe it's a brand or rejection rating kind of thing.
