Hey guys, starting about 4 months ago, I have been constantly battling leaks
in my 1/2 inch drip lines. After I fix one, a couple days later another
point in the line has cracked and starts spraying water. My house is about
9 yrs old (also live in the Phoenix area where it gets a bit warm) - is it
possible the line is just so old that the whole darn thing needs replacing?
Do pressure regulators go bad - if so, could increased pressure cause this?
Any ideas?

Thanks,

Bob
