Don't really know how your waatermaker works but what happens if the output
goes "sour" after you have sampled and redirected it? I would guess the
"automated" monitor you mentioned is most likely "real time" and should
catch a failure at any time during a watermaker run.

You know me better than that! To me KISS is something that gives you

This system is a result of 30 years in the software business learning
never to completely trust a computer. :-) It is as automated as I can
make it with push button operation and auto backflush but with mandatory
human intervention at critical points and manual overrides everywhere.

I added a Hanna electronic TDS sensor wired to a 3-way solenoid. When
the TDS drops to acceptable levels the product diverts to a second
solenoid and that outputs to the manual sampling tap that I think I
will mound near the helm. If it taste OK I push a button to send it to
the tanks.

Your assuming that your salinity divertor is 'fool proof'??

You may be correct because, while using the product water as it is being
delivered, you would stand a better chance of noticing your coffee is a
bit
salty.

My set up will deliver the product water to the tank fill manifold..

I may rethink this since I could fill a tank with bad water and never
know
it.

I was onboard a friends boat and he had the product water line coming to
his
galley sinks where it ran down the drain until he took a final "taste"
sample.. If it was good, he turned a 3 way valve that sent it to the
tanks.

My HRO system has a remote control/indicator panel with both audible and
visual alarms to indicate any fault in the system or product water.. I
haven't installed it yet, seems to complicate the system too much.

I kinda like my friends simple method. KISS..
