Certikin 6″ Concrete Drain C/W Old Grille (HD33D)

Certikin 6″ Concrete Drain is an essential component for any pool, designed to facilitate water filtration and pool draining with efficiency and safety in mind. The HD33 model, featuring Certikin’s innovative grille design, is a top choice for both concrete and liner pools. This versatile drain is a key element in maintaining the cleanliness and functionality of your pool.

Constructed from durable white ABS material, the Certikin 6″ Concrete Drain ensures longevity and reliability. The inclusion of self-tapping fixing screws enhances the installation process, providing a secure and stable fit for added peace of mind. Whether you have a concrete or liner pool, this drain is a practical and effective solution for water circulation and maintenance.

One of the standout features of the HD33 drain is its high flow and low velocity grille, setting it apart from other models in the market. With up to 50% more free flow area, this drain optimizes water circulation, promoting efficient filtration and ensuring a cleaner pool environment. The anti-vortex design further enhances safety by minimizing the risk of entrapment or suction.

For commercial installations or shallow pool applications, the option of a stainless steel grille (CK33S) is available to meet specific requirements and regulations. Additionally, Certikin offers a square frame and grille range tailored for commercial setups, providing flexibility and customization options to suit various pool designs.

When selecting the appropriate main drain size, it is crucial to consider the total flow that may pass through the drain to the filtration system. Proper sizing ensures optimal functionality and prevents potential issues related to water circulation. In normal conditions, the flow distribution between surface draw-off and the main drain(s) should be balanced according to the pool type, whether skimmer or deck level.

For commercial or shallow pool installations, the use of stainless steel main drain grilles is mandatory to meet industry standards and safety regulations. To enhance safety and prevent accidents, it is recommended that main drains are strategically positioned to eliminate any risk of bathers being pulled towards them or trapped in their vicinity.

For all pool installations, including residential setups, it is advisable to install a minimum of two main drains positioned at least 2 meters apart. This configuration not only enhances water circulation but also serves as a safety measure to prevent any potential hazards associated with the main drain area.
