Certikin High Flow Low Velocity Main Drain Grille is a top-of-the-line solution designed for shallow learner and plunge pools, ensuring maximum safety and functionality. Crafted from durable stainless steel, the CK33S Grille is built to withstand direct foot contact with the pool floor, providing peace of mind for pool owners and users alike.
This comprehensive kit is specifically tailored to fit seamlessly onto a standard HD33 or HD33L sump pot, offering easy installation and hassle-free maintenance. The inclusion of a Hydrostatic Relief Valve (CK34S or HD34) further enhances the product’s utility by safeguarding against potential damage caused by rising water tables.
The innovative design of the HD35 Collection Tube works in conjunction with the hydrostatic relief valve, efficiently collecting water from the underside of the pool floor and diverting it through the main drain. This intelligent system not only helps maintain the structural integrity of the pool shell but also prevents any water-related issues that may arise due to fluctuating water levels.
With a focus on both performance and durability, Certikin High Flow Low Velocity Main Drain Grille is a must-have accessory for any pool owner looking to enhance the safety and longevity of their pool. The high-quality materials and meticulous craftsmanship ensure long-lasting functionality, making it a reliable investment for years to come.
