I agree with Tim, but I am curious why tap water is being used to
make the 70% alcohol instead of DI water. Tap water has been known
to have all kinds of contaminates.

Matt, we have seen that in one of our VIP5's and we do weekly hot-
water rinse of the first 4 stations. It is the oldest processor,
at about 7 years. That processor had frequent pump-in pump-out
errors randomly in the first 3 stations. Finally the service tech
decided to "get to the bottom of it" and he found the steel tubing
clogged with "sand." It took a whole day to clean it all out. It
did not look like formalin salts, but did look like the kind of
deposits that you see with hard water in pipes.
Since then, no problems at all.

Hey Histonet,
We have a client who is having an odd problem with their processor.
They are getting "sandy" clogs in station 3. The original thought
was that it was formalin salts but the texture and color was wrong.
Also, station 3 is 70% which should be weak enough. One of the
techs mentioned in passing that the water quality in their town was
really bad. I think that the problem is that, like formalin, the
alcohol is causing dissolved minerals to be released from the tap
water they use to mix their 70%. Has anyone seen this before or am
I chasing a harebrained theory? Any thoughts would be greatly
appreciated.
Thanks
Matt
