    What would cause a broken water pipe? It is 2 1/2 years old. It is completely erroded at the connection...1/2 of the pipe. The plumber said they used compression fittings, it looks like flux ate it away. The ph balance of the city water is fine, the velocity is fine. If it is electrolosis, wouldn't the plumber know what pipes are compatiable? I am taking the builder, plumber and developer to small claims. The builder and developer are giants in the southern WI area.....I bought my house breand new....don't expect any of the old house issues to arise, yet alone a broken, erroded water pipe after 2 1/2 years! My warranty expired 5 months prior to the pipe breaking.....figures! Not to mention my terrace is all dug up, the bill was $1865!!!! I have the pipe, that is my best defense to show the judge. Theoretically, the pipe should last the lifetime of the house.....not only 2 1/2 years....any suggestions on presenting my case????

    If they used compression fittings, there was no flux or electrolysis. They might not have made a tight connection, or it may have deflected and started leaking, either of which can happen with compression fittings which is why few "professional" plumbers will use them, especially underground or in a wall. That leak, if there was one, in combination with the soil composition could "erode" the tubing.

    thanks for the note! So the compression fitting, the big nut type thing would not create electrolysis? The pipe as I said is about 2 1/2 years old and looks like it is 50 at the connection.....metal is completely erroded over 1/2 of it, pieces are missing. This was the main connection to the city water pipe shut off valve. So compression fittings should not be used there? Any other help would be appreciated!

    pipe

    What kind of compression coupling was it? When you say "big nut" was it a compression coupling with rubber washers in it? If so, was it brass or steel? In any case, neither one would cause electrolysis failure of the pipe. If anything electrolysis would have attacked steel coupling.

    there aren't any rubber washers in the "big nut" compression fitting. I just have the nut and the copper pipe piece the plumber cut off. I am not sure if the nut is steel, maybe. It is at home and so I am not sure. The copper pipe where it would connect to the city shut off valve, is where the pipe "rotted" and erroded away in pieces. My frustration is this shouldn't have happened so early. 2 1/2 years old. Could it be possible the plumber also used flux to explain the eating away of the pipe only on 1/2 of it....the bottom 1/2 of the pipe.......???????

    Gary Slusser That's all folks!

    Flowing water containing high levels of TDS, chlorides, sand, silica etc. act as a slurry and can cause erosion of metals.

    No water line material is going to last the life of the house.

    No, maybe it won't last a lifetime, but it should last longer than 2 1/2 years!

    IF there are no rubber washers then the compression fitting should be copper. There is no reason why the plumber would use flux on it, especially on just one side, unless he soldered the connection, which you say he did not do.
