Y-strainers have a Y-shaped body with a removable screen or mesh filter inside. They are typically placed before vital equipment, such as pumps or heaters, to prevent clogs and protect the components from damage caused by debris.
- Y-Connector: A plumbing fitting that allows the branching of two or more pipes or hoses in a Y-shaped formation. Y-connectors enable water flow to be redirected or combined between different sections of the pool’s plumbing system. They are commonly used to create multiple outlets for water circulation, such as in water features, or to connect various pool equipment for efficient operation.
Z
- Zeta Potential: Zeta potential refers to the measurement of the electrical charge on particles suspended in the pool water. It is an important parameter that affects the stability and coagulation of particles in the water. By understanding and controlling the zeta potential, pool owners can effectively manage water clarity, filtration, and the overall balance of the pool chemistry.
- Zero-Clearance Pump: A type of pool pump designed for installations where space is limited. Zero-clearance pumps feature a compact design and are specifically engineered to fit into tight spaces without compromising performance. These pumps are ideal for retrofitting or situations where traditional-sized pumps may not be suitable due to space constraints.
- Zoning System: A control system that divides the pool into separate zones or areas, each with its own equipment and settings. Zoning systems allow for customized control and management of different pool features, such as waterfalls, spa jets, and lighting. By independently regulating each zone, pool owners can optimize energy efficiency, tailor the pool experience, and effectively troubleshoot any equipment issues within specific areas of the pool.
