Custom irrigation waterline in the backyard is shooting out water from the ground. Customer do not use irrigation system anymore. Recommended customer to cap off the supply line to the irrigation system and if it ever need to be replaced, they can call landscaper to replace the pipe. I dig and cap off the irrigation 1 inch PVC waterline at the valve box. after I put dirt back together and put box back. Also capped off 3/4in pvc irrigation water line in the back yard.
