Troubleshooting
If valve function is adversely affected by accumulations of biological matter,
it may be possible to dislodge the material and restore proper function
through one of the following methods:
• Flushing and/or pumping the valve (only for those valves
without SIPHONGUARD)
• Multiple programming attempts
If these remedial steps fail to rectify the problem, replace the valve.
