North Marin Water District

That depends on what pipe you need to find. The main line usually runs in a straight line between your meter and house valve

You could call customer service and ask. They for sure would be able to give you the pressure going into the house. I don't think they will give you the pressure after the irritation valves going into the drip system.

Once your call the water district it takes about an hour. Call the nmwd number for dispatch and they will come out to you within the hour upon paying your bill.
