Just moved into a new house and am trying to figure out the sprinkler system. The house was built in the 60's and it appears (Found the manual for the pump) the irrigation system was installed then as well. The heads don't pop up, but a small stream of water flows out and puddles up around them. If I take the heads off and run the system there isn't really any pressure coming out of the pipe. However, we took the pressure tank off and we're getting a lot of pressure from there. - Not sure how much exactly, the pressure gauge looks to be not working as well.
Here are some details about the system:
- Runs on well water with a submersible pump. Don't know where the well is though.
- Single zone for front and back yards (as far as I can tell)
- 7 heads in back yard and 5 heads in the front (that we've found so far, most were covered in the grass)
- The house was unoccupied for ~3 years, I'm assuming the sprinklers haven't been ran for at least that long.
I'm thinking there is a broken pipe somewhere or an obstruction. But where? How can I track down why and where we're losing pressure? Is there anything I can do other than digging up the entire yard?
