The tubing is stainless so no issue there.
Unfortunately, I do not believe I have sufficient
vertifcal clearance to generate adequate gravitational
velocity, as my system is presently configured. It
could be change, but that would aquire some re-design
work. I was going to purchase a March high temp pump
as well, and use it only for pumping sparge water,
sanitizing and chilling wort.
I guess I will do some experimenting with boiling
water after i finfish up putting the chiller together
and see if the gravity method will work.

Will,
If the chiiler has a copper tube that the sanitizer
will contact I
wouldn't use Star San. It attacks soft metals -
take a small piece of
copper and place it in Star San for a while and it
will get very shiny
and eventually even red.
I use boiling water to sanitize my chiller. I
recirculate boiling
water through it wile boiling the wort. I also pump
boiling water
through it after chilling a batch, that helps clean
it right away. The
boiling water also takes care of the hoses.
Every few batches I'll pump some hot PBW through it
to clean things
real well. The PBW helps clean up the mashtun and
kettle as well.
For my system I use gravity to drain hot wort
through the chiller into
carboys. That way I have less hose and machinery to
worry about
getting sanitary in the path. Since I went to the
boiling water
sanitation that really wouldn't be that much of an
issue but I have the
hoses setup for the gravity path. Using the gravity
method I am less
likely to suck air into the system which could
accelerate oxidation of
the hot wort.
Note, I have a March pump that can take boiling
temperatures.

Hi,
I am finishing up construction of a 50 Foot
Couterflow
chiller. Now I have a few questions about putting
it
into use:
1. Would PBW and Star San be the preferred methods
for
cleaning and sanitizing the counter flow chiller
after
use and before use? Any point in allowing boiling
wort
to sit in there for 10 minutes prioir to
commencing
chilling?
2. Would it be necessary to use a pump to pull the
hot
wort through the chiller in a timely manner? It
seems
like it would take awhile for the wort to wind
its
way
through the 50 feet of tubing.
3. If using a pump, I assume that the flow would
have
to be throttled back in order for the wort to
come
out
at the correct temp.
Any other tips or recommendations are always
apprecieted.
Cheers
WH
