Help. Tonight I noticed water bubbling up. found a hole about 1/8 " around. cut it and put in a coupler? and about a foot away a smaller hole. Think it's 80 psi pipe and we've lived here 20 years. thinking about replacing that section of pipe (one inch) but now I'm worried...is there a life to sprinkler lines and am I going to have leaks springing up all over the place? the are that was leaking was over a septic tank, if that makes a difference.
