This product is designed for the installation and hose connection of fountain pools (in water). Individual outlets can be adjusted or turned off in terms of flow, but water may pass through the valve to balance pressure. The hose distributor for fountains features inlet and outlet sizes of 1/2 or 3/4 inches, allowing secure connections for various hoses and enabling custom water features. Compatible with pumps with flow rates up to 1500 liters per hour, making it suitable for use with many standard fountain systems. Do not use with high-pressure pumps or flow rates exceeding 1500 L/h. Suitable for use with fountain pumps such as ASIN: B01GCE2OTC. This hose distributor is intended solely for fountain systems and is not suitable for garden irrigation or similar applications. The unit balances internal pressure and allows water drainage through the regulator; therefore, it is not leak-proof and must be installed within the pool.
