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.
