Are copper pipes suitable for supplying potable water to our houses? If not, do you know about the risks and what is the best material to be used in water supply systems? I want your answer to emphasize on whether or not copper pipes can supply potable, drinkable water. Thank you in advance.
Copper pipes are ideal. The only possible issue is the lead in the solder that a plumber would use to join the pipes. But, copper pipes are very strong and last a long time. Also, when water flows through copper pipes, it picks up trace amounts of copper ions that are actually good for you (it's how your body gets the trace amounts of copper you need). When I had my house remodeled, I had the entire house replumbed with copper piping all the way out to the water meter. It was more expensive, but it is sturdier and toxic chemicals in the PVC can leach out into the water supply, especially if the water is hot or it sits stagnant in the pipe for a long time.
Sorry, this is not a cold air intake. This is hot underhood air which is no where as good as your stock intake. Simply slide in a KN airfilter into your Grand Am. Take a hard look at your source of air in your stock set-up. It's outside air which is colder and contains more oxygen
No, a cold air intake does little to nothing for a vehicles performance or gas mileage. The air fuel ratio will stay the same, and the O2 sensors will not cause an SES light to come up.
Copper pipes are usually used in house plumbing and all water coming into a house thru municipal supply is considered potable. Being a metal I'm sure there has to be some amount of trace elements in the water but it's not enough that people have stopped using copper. House plumbing was also seen with galvanized steel (not recommended because they rust closed over time) and now people are using a plastic pipe called PEX because it's a lot cheaper than copper and easier to install. Those probably leech chemicals too. Overall, copper is a fine choice for transporting potable water.
