in THE MAIN WALL
anyone everheard of PVC pipe offgassing to the point of danger with respect to causing cancer ??? I never had but evidently there are some who fear this. Consequently I may have to go back to cast iron and copperon this house. Cast under the slab is really no problem other than I don't really want to do it, and copper in the walls and to vent out through I can do also but it seems I remember reading on the Wall sometime back that someone makes a "glue" of some sort for copper pipe. This may speed things up a bit.
Thanks in advance if you can send me a post with info on this "glue"

    Maybe when it burns!

    I do recall Kansas City has some issues with stuff leaching from PVC water mains on dead end runs into subdivisions. Something to do with chlorine levels in seldom flushed mains, as I recall. Just a little something more for their paranoia :)

    Ever see the inside of copper pipe after it is soldered? Water soluable flux or not, it's pretty ugly looking. Even years later :)

    not a problem

    except on potable water lines. PVC has been found to leech out in the water at low levels. Definately not a problem in other applications except in fire, but than you have to worry about the furniture, carpet, wall paper etc.

    PVC Offgassing

    With regard to your concerns about leachate levels from PVC piping products I would not lose alot of sleep over it. Most PVC water piping products available in N. America are tested & certified by NSF under their standards NSF 14 & 61 and Canadian standard CSA B137.3 as suitable for use in a potable water system. This testing includes leachate testing down to parts per million for a number of organics and minerals. Rigid PVC (pipe material) is basically an inert product and no offgassing occurs in traditional use after the product is manufactured, as a matter of fact a US manufacture has recently introduced a PVC piping product suitable for use in pure water applications applications. Rest easy - PVC has been used in residential installations for a few decades and more recently for commercial and institutional applications with no problem.

    That's a new one to me

    Sounds like overactive imagination.

    PVC is quite stable, and the chlorine leach is not a problem in almost all circumstances. As for outgassing, what I smell is a trace of the manufacturing lubricant.

    The glue is a whole different thing. I love the "low VOC" labels on things that just about make me pass out. It's highly volitile and at least moderately carcinogenic. On the other hand, with it's high volitility it's gone in a few hours with no long term risk to the occpants.

    Now I'm not a fan of PVC and use it only what I can't find an alternative, but that has nothing to do with leaching or outgassing. It's stuff that is a long term poison, and as it breaks down it makes more poisons. If anyone knows of a moredately cheap alternative for irrigation, I'd love to hear about it.
