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?
No responses yet? Ok Bob, I'll give it a shot. These regulators do
go bad- I had one in the house do that, allowing excess pressure into
the system. You might try just adjusting it first. Is there (should
be) some place to attach pressure tester? eg, near backflow preventer?
Next, replacing it. Be a drag if you have to replace lines, though it
may come to that.
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
My house is 8 years old, let you know in 2 years ;-).
Seriously, this is the first house in AZ that I have had
drip. Builder did the front landscaping, I did the back,
no problem with either so far, be interesting to see
which lasts longer. I would think, if the pressure isn't
too high, that buried drip lines should last quite a
