We have been repairing leaks with the irrigation system as start up of the season begins. Most of the problems have been do to shifting of pipe tees or pipe sliding out of joints. The wet weather last fall and winter freezing can cause the pipe shift. Unlike home systems were the pipe is glued together. large systems use slip gasket fittings that can move if the ground become to wet. The other problem is concrete thrust blocks that were used to keep the pipes from moving were not secured good enough during construction . This shifting can happen over years of constant water pressure and soil shifting, after all the system is over fourteen years old.
