Installation Notes

Installation should be performed by a licensed well driller or contractor familiar with well sealing standards. Ensure the casing surface is clean and level before securing the cap. Electrical pass-throughs should be properly sealed to prevent moisture ingress. Use a torque wrench or appropriate tools to achieve uniform compression without over-tightening.

Contractor Application

• Protects well systems from insect intrusion, debris, and surface contaminants
• Ideal for new well installations, cap replacements, or upgrades from vent-only designs
• Field-proven design allows for fast installation and long service life with minimal maintenance
