    Re: copper water pipe system

    I used to think copper was king until I started working in San Luis Obispo County. The water chemistry can create pinholes in less thn 10 years in L copper. I was very skeptical about pex when it first came out and refused to install it. After 2 installation seminars and talking to several plumbing contractor friends who praised it I now use it mostly as an alternative to high priced and sometimes unsuitable copper. I still rough in tub and shower valves and hose bibs with copper for ridgidity.

      copper all the way for me.

      the mineral content in water is a factor that one must consider. it just makes me wonder, if the water is corrosive enough to eat the copper, what's it doing to your guts?

      reaming is very important to prevent premature failure of the pipe. i will admit, i have gotten into the habit of not reaming. i know, my bad.

      i have noticed that the higher the chlorine content in the water the faster things fail.

      i don't know about the rest of you, but i find 50psi way too high as a operating presssure for domestic water systems. we have that pressure in the system, yet we install flow restricter's.

        I just cant lower my self to use pex and plastic pipe in a house ...
        what happens if a mouse gets in there,,? he wont chew the copper pipe..
        It would be more like the holes in the plastic ice maker lines..
        Copper around here last as long as the house does,
        COPPER ALL THE WAY why pay a plumber to crimp that stuff together

            Some of you guys need to remember that if most of the contractors are using pex in that area (with great success) and you bring in your copper re-pipe bid you will soon loose lots of potential jobs. Corrosive water, and the high cost of copper is a major factor and I don't use type M junk when I do use it............my 2$ of reality

              This is exactly why we use Pex on a majority of our jobs, Type L copper would be great, but it raises your prices so much that your quantity of work would drop. For a one man shop this might not be a bad thing. for larger shops, we need a good quantity of work to keep things steady.
              No, it's not rocket science, it's plumbing and unlike rocket science it requires a license.

                I'm just glad that copper prices dropped from $70 for a full length of L to $26. It definitely makes those bids with copper a lot easier for the customer to swallow!

                  I love copper. In my area it lasts well over 50 years. While pex has some benefits it still looks horrible.

                  Plumber don't let friends use pex.

                    When I first saw slide shows on proper installations of wirsbo pex I thought what a bunch of spagetti looking crap! I was old school union trained, copper: straight, level, clean, beautiful............Times do change or we get left behind; unfortunantly.

                        on each side of the ball ...also known as a circuit setter
                        and that will work also

                        your right that would be a problem... i was just trying to give a general answer

                        this post is g2g

                        if your using a centrifugal pump putting a valve on the discharge side wont do any damage unless the valve is shut causing the pump to dead head and overheat
