CMP 25513-300-100 Gunite Main Drain Without Lid, 3″, White

The CMP 25513-300-100 Gunite Main Drain Without Lid, 3″, White is a precision-engineered pool component designed to provide reliable and efficient water circulation for gunite (concrete) swimming pools. Built with durability and performance in mind, this 3-inch main drain body serves as a critical part of the pool’s circulation and filtration system. It helps draw water from the deepest part of the pool, directing it toward the filtration equipment to ensure proper water turnover, improved clarity, and balanced chemical distribution. Manufactured by CMP (Custom Molded Products), a trusted name in pool and spa components, this main drain body reflects the brand’s commitment to high-quality materials, structural integrity, and long-term performance in demanding aquatic environments.

Designed specifically for gunite pool installations, this main drain body integrates seamlessly into concrete pool structures during the construction phase. Its rugged construction allows it to withstand the pressure and weight of surrounding concrete, ensuring stability and proper alignment once installed. The 3-inch port size supports efficient water flow, making it suitable for residential and commercial pool applications where optimal circulation is essential. By facilitating smooth and consistent water movement from the bottom of the pool, the drain helps reduce stagnant zones and enhances overall system efficiency.

The white finish of the CMP 25513-300-100 provides a clean and professional appearance that blends naturally with most pool interiors. Whether the pool surface features plaster, quartz, or other light-colored finishes, the white drain body maintains a subtle and unobtrusive look. Its color stability is designed to resist fading and discoloration caused by prolonged exposure to sunlight, pool chemicals, and varying water temperatures. This ensures that the component maintains its aesthetic appeal over time, even in harsh outdoor conditions.

Constructed from high-quality, corrosion-resistant materials, this gunite main drain body is engineered to perform in environments where constant exposure to chlorinated or salt-treated water is common. The robust plastic formulation resists cracking, warping, and chemical degradation, offering dependable performance season after season. Its structural strength supports long-term use without compromising the integrity of the pool’s circulation system. Because it is supplied without a lid, it allows pool professionals to select a compatible drain cover that meets local safety codes and specific project requirements, providing flexibility in design and compliance.

The 3-inch plumbing connection is designed for compatibility with standard pool piping systems, simplifying installation and integration into new builds or renovations. Proper water circulation is fundamental to maintaining water clarity and hygiene, and the CMP 25513-300-100 plays a vital role in achieving balanced suction from the pool floor. By drawing cooler, denser water from the bottom, it supports even temperature distribution and helps the filtration system remove debris and contaminants more effectively. This contributes to cleaner water and a more comfortable swimming environment.

In addition to supporting filtration, the main drain also assists in pool draining and winterization processes. During maintenance or seasonal shutdowns, having a reliable main drain body installed ensures efficient water removal when needed. Its solid construction minimizes the risk of leaks or structural failure, which is crucial for maintaining the integrity of the pool shell. For contractors and builders, choosing a dependable drain body like the CMP 25513-300-100 helps reduce callbacks and enhances customer satisfaction through long-term reliability.

CMP’s manufacturing standards emphasize precision molding and consistent quality control. The design of this gunite main drain body reflects careful engineering to ensure secure pipe connections and a watertight seal when properly installed. The unit’s shape and configuration are optimized for embedding within gunite structures, allowing it to become a permanent and stable component of the pool system. Its straightforward design also simplifies alignment and plumbing during construction, helping streamline the installation process for professionals.
