not enough pressure in all zones

[buikemakathy]

Hi,
We just turned on our system this spring. Everything thing starts up o.k but we have noticed a lack in water pressure compared to previous years. Any clue what this would be?

Could be any of several things, but we would have to be there to make the necessary tests.

Just a couple of shots in the dark. Could be a main valve is not opened completely. Could be a leak in the line coming to the manifold. Maybe a defective backflow preventer.
