[AT] OT: chemical containers Ron Cook and others

[charlie hill]

Good ideas Herb.   Mine will be used initially for water for pressure 
washing.
I've washed them with ammonia water and with Dawn dishwashing detergent.
Both are well known for cleaning ag spray tanks and are very effective.  By 
the
time I get through pumping several thousand gallons of pressure washer water
through them they should be safe for whatever I decide to use them for. 
However,
I doubt if I ever store potable water in them.   I know where I can buy more 
(these
were free) for $65.00 each that I KNOW had food grade products in them and
are single use.

We have five such tanks catching rain water from one side of our shed and
two such tanks catching rain water from west side of our home. Have done
similar projects on five tanks for gardening friends.  Several tanks had
"release" for spraying plywood forms before pouring concrete, so forms could
be removed from setup concrete without destroying forms, another had a
powder used around operations involving much cutting of paper (keep dust
down), couple more had sat long enough that chemicals in bottom had
evaporated and dried; physically removed residue with mop on end of long 2"
x 2" after no luck with gasoline, and several other chemical liquids.  Above
tanks had large, professional labels secured to side; I had no way of
knowing if this label applied to the last time this tank was used, however
the tanks were in good condition but may have been a bit optomistic in
concluding most had been used just one time.
Thank goodness I finally wised up and passed if tanks contained any liquid.
Scrubbed all tanks with soapy, hot water. We  were the only customers with
vegetable garden. Last tank was installed in 2008.
This certainly does not answer your question or concern. That uncertainty is
one reason I did not pursue this project any further; the other reason is
although customers were happy, I was only making a couple bucks/hr.
Water rates in our area are high because Lake Lanier is principal source;
and watershed area feeding Lake Lanier is vary small, and AL, FL and GA have
been in political niff-naff over water rights for couple decades.
IF YOU do such project, suggest replacing aluminum downspout with plastic
pipe with glued joints and feed water into tank through the 2" hand valve at
bottom side of tank and extend the same pipe so hose bib can be installed.
Looks neater, can leave cap (loose) on top of tank, and no mosquitos.

Ron or anyone else that might know.
I have acquired a couple of 275 gallon plastic "carboy"
type chemical containers.   There is a slight amount of
chemical in the bottom of them and I don't know what it
is.   I've noticed that both containers have a RED lid
on the top of the tank.  I'm wondering if that RED lid means
something or if that is just the color the manufacturer
decided to use?
Anyone have an idea?
I don't intend to use them for anything other than NON-potable
water storage for pressure washing but I need to know that I've
properly cleaned them.
