it may be worth reminding them that the requirements are on
antifreeze system have finally been modifid to reflect the needed
level of maintenance. For instance, a test connection at the end of
the system and additional ones per 100 gal AND if any point has too
low a concentration that the WHOLE system must be drained to modify
the concentration.
There is also the issue of increased potential for leaks. A
perfectly tight wet pipe system can leak with antifreeze solutions.
The morale of the story is - proceed with the appropriate CYA
contract language.

I know the fluctuations will subside as the season ends but they'll
be back
in the spring.
Average street is 80 PSI but with my hockey puck recorder I've
recorded dips
to 60 PSI, so much for the 10# cushion. I purposely left about 25#
on the
table for the highest density calc I had there and I'm glad I did now.
Hopefully no more rides down and plus I have to change the whole
system to
glycerin as they've sold the resort to some offshore entity and the
plan to
close it (just heard today) for the winter. Glycerin has a much
lower rate
of expansion than glycol/water and according to my Amtrol book, I
can do a
350 gallon system with a 70 gallon expansion tank. Yeah!
additional question...
Is a 55 gallon drum bung thread pipe thread? I need to make a dip
tube to
pump out 7 55 gallon drums of glycerin. Anybody know? Anyone made
one?
