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?

If you mean the pressure regulator that regulates house pressure to
the 15 psi or so the drip system wants, I'm sure they do go bad.
But more likely is that the problem lines have been exposed to the sun
for too many years. Plastic exposed to the sun tends to get brittle.

You should be able to tell something about the
pressure in the system be how hard you need to press over a leak to
stop water flow. 15 psi will stop easily. Unregulated pressure will
not.
