Backyard Aquaponics
A place to discuss aquaponics

hello
i've been searching for about 2 years, not good enough i guess, for those white DWV pipes in Slovenia and i still haven't found them just the grey high pressure ones(Georg Fisher). I was wondering if there is some european that knows a dealer of those pipes in europe?

thank you for your contributions!

matej

hey Matej,

I am in Belgium and might help you

please explain what you mean by DWV pipes and why you need this particular pipe instead of standard rainwater drain pipes

DWV = Drain Water/Ventillation.

Molj is suggesting that all he can source is pressure pipe.
Which is more expensive,

(although the elbows and tees are 90 degrees rather than the 87 of DWV)

hygcell as Kpucat said:)
thanks to both

here is a very reliable source in Belgium for all kinds of pipes
http://www.scalaplastics.com
they have just renewed their website and catalogs
they have an incredible choice
you might even find a language that suits you better )
they have a subsidiary in Poland

personally I mostly use their square rain drain pipes 100 x 100 mm as I drill holes in all horizontal sections to use as NFT channels:

hey frank
thanks for the link, i checked but they don't have the white PVC 1/2 and 3/4 inch ones
will bookmark that site if i ever use nft channels
i need piping for irrigation of the growbeds, el cheapo low pressure pipes

more info is welcome

AFAIK, low pressure pipe is not available in such sizes.
This is because low pressure is for drainage, and small sizes block too easily with detritus or airlocks.
Good luck, but the smallest I'm aware of is 40mm or 1 3/4"
the pressure pipe at 1" and below is not terribly expensive, as it's so small it has good integrity without needing extra fat walls.

apparently the english catalogue is still under construction

did you look under electro? these small sizes are used for that
not white but grey:

frank i looked at those and it looks like the piping for electric installations, and i think those pipes are made from PP which gets crusty pretty fast under the sunlight, at least they sell white ones at our local "k-mart" store

i'd really like to find the pvc-u pipes, but the closest i got were the GF pipings and they only sell high pressure ones which are expencive for this cause

so, i'm still looking for european DWV version of piping:)
thanks for everything frank

Beware of any "coloured" plastic electrial conduits... many contain lead (or other) nasty contaminants...

that is new to me
where did you get that information?

frank

I don't know where he found his info, but 2 minutes of Google turned this up
http://www.environment.gov.au/settlements/publications/waste/pvc/summary.html

As noted by Kuda.... most Australian manufacturers, even of electrical conduit... are moving away from any lead based compounds....

Worth checking it out in your location though....

Ok, you and Kuda convinced me that lead is used in PVC
I have always been opposed to PVC (and vinyl, it's weakened counterpart) as I believe it not to be the ecologically best solution

but little less is available on the market so we have to do with it at least for piping

you haven't convinced me to far that the lead used in PVC can leach into the water

please point this out to me
as I believe this to be decisive in the use of PVC in our systems

if it does,
PVC should be completely banned

Getting to the point where you need a chemist Frank. I'm just an engineer. I use stuff and believe what I'm told about it. Actually working out if we're being duped is beyond me.

The strongest telling point imho, is that pressure pipe, used for drinking supply, is not made with lead, whereas DWC and conduit can be. Sandwiched storm water pipe also has some nasty things in it.
