This project is for the installation and hose connection of the fountain pool underwater. Individual outputs can be adjusted or turned off in terms of flow, but water may escape through the valve to compensate for pressure. Hose dispenser for fountains with inlet and outlet sizes of 1/2 or 3/4 inches, allowing secure connection of different hoses to create a custom water feature. Hose distributor for pumps with flow rates up to 1500 liters per hour. Compatible 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 model ASIN: B01GCE2OTC. This dispenser is designed for use in fountain systems only and is not suitable for garden irrigation or similar applications. Note: Refer to the product instructions. The dispenser balances internal pressure and allows water to drain through the regulator; therefore, it is not leak-proof and must be installed within the pool.
