Pex and Drinking Water


Hi everyone.

I'm loving the Pex, but I've been reading that it's missing some of the antimicrobial properties of copper. I've been considering running copper to my kitchen sink and everything else in Pex. Is this silly?

Is that because you get paid by the hour?

I use a stick welder, smokes a lot but smells great if you use an apple or hickory stick.

Do you use reverse or straight polarity with the hickory rods?

Copper has well documented antimicrobial properties. PEX has no antimicrobial properties. If you are on city water, this is not an issue, since city water is typically chlorinated to get rid of microbes. Well water may have bacteria, some of which would be killed by copper. The only way to know if you have bacteria, viruses, or other organisms in your water is to get it tested by a competent laboratory.

That said, a short length of copper pipe to your kitchen sink is not likely to have much effect. If your whole house is done in copper, then water which sits in the pipes for long periods of time may be partially disinfected by copper contact, but this is not going to work for a short length of pipe in the kitchen. If this is a concern, I suggest you get a kitchen filter, there are lots of companies that make them. They are typically activated charcoal, and will remove many organisms that could be found in the water. Some of the filters will remove chlorine as well.

Awesome reply - thanks Daniel! Love your point on limited effect of a short length of copper, I think I was sort of assuming it was magical
