It does and it does not I guess. The sprinkler's do work but perhaps not with as much pressure as I would like or that I had in previous years. I do have a small pressure tank beneath the pump. I checked the pressure of the tank and it is at 40 psi. For example, on the first zone which is primarily the flower beds, the pump would actually cycle on and off every few minutes as it built up to a 60 psi over time (not ideal but what would happen anyway). On the 2nd zone, it would nver cycle off but would run at 40 psi which would give me great coverage on the front lawn.

I never mentioned this, but even when the irigation system is completed with the last zone, the pump will not build up to the 60 psi to shut off. That's what I find odd.

Thanks for your help and any further ideas.
