Thurmer,

Was this system installed by a contractor recently? Are all the zones except this one separated for their purpose (ie. lawn, garden, shrubs etc)? How many zones are there and for what purpose? How many heads and what type on each zone? Do you have pressure regulators on your drip line? Describe your system in as much detail as you can. Aloha

This wasn't installed recently, it's been there for at least 3 years (as long as I've lived in the house). Zones 2-6 are all for different areas of the lawn. Only zone 1, the drip line linked to the timer, is for the shrubs. There is also a manual drip line for vegetables and flowers in the back, but not connected to the automated drip line. For the most part all the sprinkler heads throughout the lawn are standard pop-up sprinkler heads, there are a couple of the adjustable rotor heads in the back. I don't believe there are pressure regulators on the drip line.

Anyone that can offer any help? I really don't know much about sprinkler systems and would appreciate any sort of input......
