Which statement about flush mount well covers is true?

• A. They should be installed without any base material
• B. They require tar sealing
• C. They use a wooden base
• D. They should have concrete in the base

Answer: (D)

Flush mount well covers need a solid, durable base to function properly. The base provides structural stability so the cover stays level and doesn’t shift or settle under foot traffic or weather. It also creates a tight seal around the well collar, helping keep surface water, debris, and contaminants from entering the well. Using concrete in the base achieves these goals by providing a long-lasting, weather-resistant foundation that supports the load and maintains a flush surface with the surrounding grade. Tar sealing isn’t standard practice because tar can degrade, harden unevenly, and isn’t as durable or cleanable as proper concrete sealing. A wooden base is vulnerable to moisture, rot, and pest intrusion, making it unreliable. Installing the cover without any base material would leave the installation unstable and prone to movement and leakage.
