  • Cause of leaks in horizontal pipe

    My parents have been living in the country for around 11 years. They have well water and it's soft. They've had about 11 leaks during this time. All pinhole leaks and only in the horizontal lines in the crawlspace. They've never had a leak in the wall. Are my parents lucky or is their a reason behind this?

    You are a plumber. Give more information.

          1) Type of pipe.

          2) On fittings or pipe.

          3) Hot water, Cold Water, or Both.

          4) Circ. System, if on Hot Water.

          5) Age of system.

          Those 5 would be a start. What do you want, mind readers? I thought you were a plumber. Read your own question and see if you can answer it with the information you provided.

              ben, glad you posted this here. didn't look at bhd's links yet.

              i felt that trapped co2 is the culpret in the pin hole issue.

              i think mark/ utah is up on this

              get a chance and read the links from bhd. he is usually 99.9% dead on with his research and info

                With just the horizontals leaking and the lack of other info Rick sounds right on. If that is what is going on it is fairly normal for suspended CO2 in well water to do just that.

                    Sorry Dog, wasn't thinking the whole thing through. By the way, how many times have you ever gotten your a$$ kicked for the way you talk to people?

                      Type L copper pin-holing after only 20 years of service?

                      Has the well water been tested?

                      Doesn't really matter at this point it's already too late to save this copper from further leaks.

                      Time to repipe...good thing they know a plumber

                        Pressure and pipe size are important factors also. Well water typically isn't soft (at least around here anyhow)

                        Pitting is almost always associated with hard well waters. Well waters treated to raise the pH to 8.0, or above, to remove dissolved carbon dioxide are generally rendered non-corrosive to copper. Aeration is also an effective means of removing dissolved carbon dioxide, and has the added benefit of stripping dissolved hydrogen sulfide from the water, when present. Well waters in some areas of the contain hydrogen sulfide which not only causes an offensive odor problem, but also promotes cold water pitting of copper water tube. Treatment schemes to remove hydrogen sulfide generally rely on a combination of chlorination and aeration.

                        Acidic Water (low pH) indicates intensity of a given water in terms of alkalinity or acidity. Acid or alkaline strength is measured on a scale that goes from 0 to 14. The mid point being 7 is the measure of neutral water, neither acid nor alkaline. Acidic water is any water with a pH below 7.0 with the acidity increasing as the numbers get smaller down to 0.

                        Significant amounts of dissolved carbon dioxide (co2) are often present in groundwater, which if not properly treated, can be extremely aggressive to copper tube. The effect is most commonly referred to as Acold water pitting, and is characteristically observed in cold water piping, but not in hot.


                        A copper water distribution system should be designed so that the water velocity through the tubes is within the range of 5 to 8 feet per second (fps), depending upon the tube size and the water pressure. For the smaller tubing sizes normally installed in home plumbing the design velocity should be targeted toward the bottom of the range. (4 to 5 fps)

                        As one would expect, the greatest effect of velocity occurs where the water is forced to change flow direction, such as at elbows and tees, but excessive water flow rates can be damaging to the entire plumbing system. When copper tube is installed that is too small in diameter for the pressure and flow available, the resulting high flow rates can erode the protective coating creating areas of bare, unprotected copper. This effect can result in a high rate of corrosion wherever the protective coating is eroded.
                        You will never expand your mind, if you do not challenge your beliefs.

                          Why are you always writing books everytime you post?

                          Also if you are on this forum and other forums all the time when do you work?

                          Also if you have your own forum why aren't you there?

                            If it was me I would start by checking the pressure and pH level of the water (litmus paper is inexpensive) and go from there.

                            You may have to treat the water, at which case you would probably be better off using a pro service. Being a city dog I don't have much knowledge of wells.
