Yes, DS's sediment filter was virtually the color of Blood Oranges from
California.

Btw, I'm still trying to figure out (for myself I guess) why you had such issues
with the new unit. Is there any chance that your PSI guage is incorrect and
your water pressure is perhaps much much higher?

Feel free to reply in email if you like. This thing is just bugging me, and
until you are compeletely happy.... well, you know the rest.

I understand compleatly why the first bit of water through the membrane is
not as pure as the latter and it has a higher TDS. but the flush kit
doesn't amount to a hill of beans when it comes to cleaning the membrane.

and with Bill Kirkpatricks explanation in mind I took the restrictor off my
old unit (has never been flushed in the 2 yrs it has been in service) I then
allowed the waste water to 'flush' over some filter floss and it didn't have
any gray or any other color junk from build up.

I sent pics of my sediment filter to Marc when I swapped it out, I think he
could testify that if there would have been a build up on my membrane from
not flushing it over those 2 yrs, I would have defiantly been able to see it
when I flushed it.

KC, normally do not need to use a flush kit if your RO is in constantly
using it.

Taking your example by using a garden hose and make a hole in the middle.
Well, if you can cap or close the output of your garden hose, the garden
hose will gather somewhat of debris or dirt particle. Since inside the
garden hose does not have any filter or barrier, it will not gather much
dirt or debris. But if you do not make a hole in the middle of garden hose
and open the output, you might see some particle. But if you did have a
hole
in the middle and the water pour out while the hose not being use but when
you open the end of the hose, you may have water comming out with less
dirt
particle.

Imagine this. Put a coarse sponge or filter between the output and the
hole
you made and do the above example. When you open the middle of the hose,
it
will remove water and carry any possible dirt with it instead of cloggin
more to the coarse sponge or filter. This in turn will make your filter
last
a bit longer.

You do not want solid to creep through your membrane spore. With Flush kit
or flush valve, you preventing solid from cloging your membrane and other
filter by reject water and at the same time removing solid instead of
creeping to your filter.

How much it will cost you to refil your filter and how much many time you
need to buy a flush kit or valve ... The idea here is to make your filter
last longer as much as possible. The solid will creep thru while water is
not moving or idling in your unit. When it the solid attach to the spore
of
the filter, it will clog it. When flushing, the solid may not have attach
or
clog your filter but remove when water flow out.

When you use the RO unit, your first batch or cup may have higher solid.
The
reason may be some solid may have creep thru while your unit is idling.
Use
a TDS meter for the first batch and test again for next batch. You will
see
a bit.

Am I making any sense here or I am talking to myself?

I hate to disagree with you Cap but saying the flush kit will do
anything
at
all is just (pardon my French) a bunch-ah-****.

that would be like saying if I took a garden hose and turned it on full
stream then went and stabbed a hole in the middle of the hose to allow
water
to come out, that the water coming out the end would be cleaner water.

the flush kit does not flush anything, it just allows more water to pass
around (not inside) the membrane housing.

I've done some checking on flush kits, and everything I've found on
the
topic
seems to indicate it is more hype than benefit. It does not rinse
the
RO
membrane in any form or fashion. Others may have more comments on
it.
It
isn't
difficult to install one, but I just don't see the need.

It better to flush it, the membrane will last longer. You do not want
bad
water to sit there to long.
A flush kit will reduce waste ratio, especially in low TDS while
maintaining
or improving systemTDS reject rate and extending membrane. The auto
flush
flushes the system for 18 seconds every hour removing damaging
particulates
from the membrane surface prolonging its life and rejection quality.
