It's probably condensation. I'm here in central Florida
and it does not get very cold here, though it does get
down to freezing from time to time. Here at the store, to
make better use of the waist ro water, I sent the waist
water to the toilet, but the cool water was causing a
problem of condensation on the toilet seat. So I added a
little bumper on the toilet seat lid to raise it up a bit,
and that took care of that.

You might be getting a lot of air in your tap water. Check
for that. As for flushing a new membrane, you should flush
about 5 gallons.

Thanks for the info. As for condensation, that is possible, although I
am in Northern California, so cold is a relative concept. We've had a
real cold snap lately (hi 20's-low 30's), but we don't usually get
below the low 40's/ high 30's, and this problem started before the cold
snap (although not before the generally cooler winter weather).

I think air is the cause of the buzzing; it often happens after I've
opened one of the filter canisters, and when that happens, it will stop
if I open the output valve and let it run for a minute. On the other
hand, when I recently changed the filters, I let it generate a couple
of gallons of output to flush the new elements. Shouldn't that have
bled any air out of the system? The buzzing seems random; it will be
fine for hours and then all of a sudden buzz it will buzz for several
minutes- sometimes as many as 10-15 min. Perhaps it is related to when
the automatic float lets some water in to the refugium. Is there a
specific procedure for checking/bleeding air? The only other thing I
can think of is if there is a problem with the membranes; they are only
7 months old, and tap water is good quality, but its treated with
cloramines, which I understand can shorten membrane life.
