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..

You know me better than that! To me KISS is something that gives you
Mono or Hepatitis. :-)

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.

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.

As a watermaker membrane ages and fouls it produces less fresh water but
the salts don't increase. The TDS sensor would divert the product water
if it did get over 200 ppm or so but that is not likely to happen. The
main reason for testing and discarding the first water out is that it
will be salty.

Remember that the process is "REVERSE" osmosis. The high pressure
reverses the natural tendency for salty water to migrate through a
membrane to less salty water. With no pressure the natural process
resumes and salt passes through and accumulates on the fresh water side.

Leaving the below in for context, are you going to put your configuration on
your website? I'm sure others might like to attempt your achievements at
bargain hunting and efficacy...

Yes. The pressure vessels just arrived and I will have the installation
complete enough to finish the picture series for the web oage. I have
converted the schematics and printed circuits to GIFs and have been
working on the narative.

Hopefully I can get some stuff up on the server next week and reduce the
volume of emails from impatient site visitors. :-)
