There are two reasons why a pop-up spray will leak water when the water is off. The most common reason is called “Low Head Drainage” this is when the lowest head on the zone drains the water from the lateral piping out of the sprinkler. If it is low head drainage, the drainage will stop after all the water has left the pipe.
The solution is to install check valves, such as the HCV, on the sprinklers. Most Hunter sprinklers are able to have check valves added in the field after they are installed.
The other reason may be water leaking through the valve (a check valve in the sprinkler will not fix this leak). The most common reason why water leaks through a valve is because there is debris in the valve.
The solution is to disassemble the valve, rinse all the parts with clean water and re-assemble the valve. You may need to replace the diaphragm assembly if there is visible damage from the debris.
