The two main pipes are plastic and metal. Plastic pipes have polyvinyl chloride and the metal pipes are either copper or stainless steel. Not all pipes have the same effective or be used the same.
To keep the population lower (thin the herd) the US government wants carcinogenic materials used in lower income housing as toxins leach into the (Potable) drinking water supply .A funeral is a lot cheaper (according to the US Senate) then having a leaches on welfare for two or three generations
Plastic.. Depends what type, but plastic pipes are made from plastic. :)
METAL Pros The good thing about metal pipes is that they are, obviously, made from strong materials. As a matter of fact, most metal pipes are made from steel, which is incredibly durable and can last a long amount of time without needing repairs. This makes metal piping a good option for those who want to get this done with and not have to deal with it again. Another great thing about metal pipes is that the backfill doesn’t need to be as carefully calibrated when you put the pipes under the floor and ground. Cons While there are many terrific reasons to use metal, and specifically steel, pipes for your updated plumbing system, there are a number of negative factors that weigh into this, as well. For example, metal pipes are usually a lot more expensive, and is only becoming more so nowadays, since it isn’t mass produced nearly as much as it once was, due to the rise of plastic plumbing. Another thing to be careful of with steel pipes is the rust that can form between the threads, as this can get into your home’s drinking water and contaminate it. PLASTIC Pros We live in the age where people love DIY projects, and often prefer to take on projects, themselves. This is a desire that is very much fulfilled by plastic plumbing pipes, as they are very easy to work with and cut. Currently, it is very easy to find unique pieces of plastic pipes for any job, as it is very popular. It also comes in a very flexible version, which can make it easier to place. Plastic is also a lot cheaper than most metal piping. Cons Despite the immediate benefits, there is always one thing that plastic will never have on metal: it will never last as long. On top of that, while it can resist a lot of heat, it is nowhere near as heat resistant as something like steel. This means that you will probably need to replace many of these pipes a lot sooner than you would need to replace a metal one.
