PVC Water storage tanks?

[bobhenry]

OK Here is a question for those of you in the know:

Does PVC gas off VOCs (Voiltile Organic Compounds)? In other words is PVC really safe for drinking water?

God I would hope so I just plumbed in my new kitchen addition and replumbed the bath and laundry room all in PVC. Supply lines and drains

TK,....the only marks on my pipe are. PVC DS MS ASTMD 279 PPFR 0105063M45

What do you think?

hmmm, i think you are missing part of the print strip. there should be a section that states the size, company name etc. these run every 4' or so.

from what you typed, it looks like your product is from a pipe manufacturer in Meadeville (Conchraton) Pennsylvania called JM pipe. (I could be wrong)

ASTM 279 if i recall correctly has to do with the bleeding of the pigment (colorant) that is used with the virgin material. Is this a co-extruted cellular core pipe? Do you have more of or can you get more of the print stip? if you bought the pipe in 4' lengths you may have to look at several pieces in the store to find one with a complete strip.

DS and MS do not translate to anything that I'm aware of... I'll do a little checking.

sorry i can't be of more help right now.

Thanks TK,...I called the company (crestline) and they said. that it is not recommended to use any PVS pipe that is not rated for drinking water for a D/W storage tank for all the same reasons you stated.

How'd you get so smart???

yep i'm an inspector, and i have inspected/audited several pipe/fitting manufacurers in the US and Canada. I work for NSF International which is the certifying labratory. NSF (formerly the National Sanitation Foundation) is an independent labratory (much like UL, CSA, ETL, etc). Anyway I audit the manufacturing practices, QA/QC practices, and materials and ingredients stuff is made out of, the proportions, and physical specs to the appropriate ASTM. I collect all kinds of samples and send them to our Ann Arbor, MI headquarters that performs the physical tests and chemical extraction tests in a controlled environment that is compliant to ASTM standards...

hope that explains a little more.

NSF International --- Live Safer! ---your public health and safety company.

anyway, when I saw the note about dwv pipe used for pw, it spooked me because i've seen the test results of these... you don't want to ignore a designation like this. dwv does not mean it's the same stuff as pw....

FWIW: I've had (and used) one of these Valterra water tanks in my trailer for three years.

"VALTERRA Water Tank 6 Gallon

ABS plastic water tanks are made from lightweight, high-grade plastic polymers. ABS is tasteless, odorless, non-toxic, and completely algae-free. Fittings can be installed anywhere on the tank with ABS glue; three 3/8" FPT inserts molded on each end. 6 gallon tank measures 8" X 16" X 12". Price: $37.34

Except for the third eye I've begun to grow in my forehead, everything seems normal --- all evidence above to the contrary notwithstanding.

those look like a good value, thanks for the tip!

So do the big box stores sell PVC-PW in the 4" size? If not, where can I buy it??

o yeah! you'll find it everywhere. I'd say it's harder not to find it. in canada you'll find a lot of stuff with ICC references too...

but just look for "NSF-pw", and you'll be fine. (NSF should be upper case, and the pw should be lower case)

It'll have a long print strip, and may be dual listed, but if you see NSF-pw you're golden.

Mounted on the outside of a TD , this would make a great hot water heater... black pipe...solar powered... mounted on the roof would be gravity feed too ...no pump...

just remember the UV factor. Also, I have never seen black pipe that is rated for potable water, it may exist, but I've never seen it. Though you could make a black sleeve over the white POTABLE WATER pipe?

[nikwax]

black paint over the white pipe would do it.

Cool !!! Er, I mean , it's a HOT idea!!! Thanks TK,nik

Guess what?? Just checked HD and Rona (canadian big box), and they don't carry PW.. Guess I'm going to have to go to a specialty plumbing shop.....

Hmmm, Home Depot should have what you need, let me see.... I'm inclined to say they absolutely must have it...

per program policy 1, "...A Product that has been Certified to Canadian and U.S. requirements shall bear the (NSF) Mark with designation "C"."

the complete print strip is long, you have to look for the info. it will look something like this:

"XYZ pipe 3" NSF-61 PVC1120 SCH40 260 PSI NSF pw ASTM D1785 ASTM D2665 NSF dwv DWV XYZ 9078 1-29-2007 XX 10 2"

you may have to look at several pieces of pipe to find the parts of the print strip, but i'm telling you it just must be there. you are looking at white PVC pipe correct? There are a few ways the stores display the pipe... make sure you check the different aisles for water pipe, electrical pipe, and drain pipe. a house can not be built without potable water pipe, so they must have it. It is not something only from a specialty shop.

just my $.02
