I recently got some advice about not having a PVC vent pipe exposed to sunlight. The plumber who helped us install a new bathroom last year replaced the top of our cast iron pipe that went through the roof with a PVC pipe, and I am sure that it is exposed to direct sunlight. Is there anything I should do to replace it or cover it? What damage can it cause?

When you stated a "plumber" helped you may I ask what apprenticeship did he /she attend?

What licenses or certifications do they posses.

How long ago did they pass the journeyman tests?

If the answer is none then I wonder if you would go to a doctor who had the same kind of training your "plumber" has.

Did your know that in many localities it is a misdemeanor to say your a plumber without the benefit of a license.

The answer to your question is NO PVC cannot be exposed to direct sun light...

Well you certainly got what you paid for AND if your plumber does not have compensation insurance and got hurt they can sue you and will win the case

So what is the answer to his question? Other than PVC cannot be exposed to sunlight. What do you use for the roof termination?

I'm an apprentice plumber, and 100% off all my installations have been PVC. I've looked in the UPC plumbing code book and have not yet found an answer for which material I should use for a vent termination.

I use No Hub cast Iron pipe and some of the codes are inferior as as the home builders have a very strong lobby and Congress /senate folks in this country are the best money can buy IMHO

Codes set minimum requirements and most code officials would never let facts get in the way to approve a material.

As long as a manufacturer has deep pockets materials will get past the public heath departments.

Here is a copy of an E mail that was sent to me

Hi Sylvan,

Last week our allies at the Center for Environmental Health revealed the Consumer Product Safety Commission (CPSC) failed to publicize testing revealing potentially dangerous levels of lead in children's PVC lunchboxes. Remarkably, after finding elevated levels of lead in PVC lunchboxes, as much as 16 times higher than levels allowed for lead in paint, the agency changed its testing procedure in an apparent effort to minimize findings of lead in lunchboxes. The agency then went on to issue a press release stating the lunch boxes were perfectly safe.

Through the years, the CPSC has failed to thoroughly respond to unnecessary dangerous chemicals in PVC consumer products. While the agency did take action when they discovered dangerous levels of lead in vinyl mini-blinds were escaping, they have failed to adequately protect the public from lead and other toxic additives in PVC lunchboxes and toys. A Greenpeace expose that discovered hazardous levels of lead and cadmium in a variety of vinyl consumer products, including products specifically designed and marketed for children, was rejected by the CPSC in the late '90s. Similarly in 2003, the CPSC denied a petition from health and environmental groups to ban phthalates in PVC toys, meanwhile these same dangerous chemicals have been outlawed in Europe.

There is however hope on the horizon. Four lawmakers, including House Energy and Commerce Committee Chairman John Dingell, D-Mich., are now considering holding hearings and drafting legislation in response to this new information. Last year, Attorney Generals from NY and CT took legal action to remove lead from children's lunchboxes. In July of 2006, the FDA ordered retailers and manufacturers to stop marketing vinyl lunchboxes containing lead, because of potential exposure concerns. The nation's largest retailer, Wal-Mart, went a step further than the FDA, and agreed to stop selling all PVC lunchboxes due to potential health and environmental concerns. Wal-Mart is also phasing out PVC private label packaging and recently unveiled a new precautionary chemicals policy.

This begs an important question - with Wal-Mart phasing out PVC lunchboxes and packaging, what is Target doing to protect our families from the poison plastic? Absolutely nothing. While Target has an opportunity to be a true leader on this critical health issue, their aisles are filled with products made from poisonous chemicals linked to cancer.

Take action today and urge Target to phase out PVC lunchboxes and other hazardous products made out of the poison plastic. After you take action, be sure to forward this on to your friends and family, and learn how you can test your child's lunchbox for lead.
