Discharge nozzles

• Concrete pools: They require specific nozzles to be embedded on site, generally more robust and with fixing systems suitable for concrete.
• Pools with liner or polyester. They need nozzles with special gaskets and flanges to ensure watertightness and avoid leaks.
• Demountable pools: They usually require special surface nozzles or adapters.

Before buying, it is important to know the exact type of pool and make sure that the nozzle chosen is compatible with the installation system of your pool.

• The diameter of the nozzle outlet determines the water flow rate it can deliver: ○ Typical diameters: 14 mm, 20 mm and 25 mm.
• A larger diameter allows higher flow, but must be in balance with the power of the pump and the filtration system.
• Recommended flow rate: Depends on the volume of the pool and the number of nozzles installed.
• It is important that the total flow of all nozzles allows a good recirculation of water without creating excessive turbulence or dead zones.
• Connections: Check whether the nozzle is threaded (internal or external) or glued, and make sure it is compatible with the existing piping.
• Choosing the correct diameter and flow rate ensures efficient circulation and avoids overloading the filtration system.

The location and depth of the nozzles is key to good circulation:

• Recommended height: they are normally installed between 10 and 30 cm below the water level.
• This favors surface circulation, pushing dirt towards the skimmers.
• Distribution: The ideal is to distribute the nozzles on the wall opposite the skimmers, so that the water runs through the entire pool in a circular flow.
• Avoid noise and splashing: If installed too close to the surface, noise or splashing may occur.
• Proper installation ensures that the water is renewed evenly and efficiently.

• The drive nozzles can be manufactured in different materials
  • ABS: The most common material, resistant to chlorine and UV rays, with good durability and affordable price.
  • Stainless steel: Very resistant and with an elegant finish, ideal for design pools or intensive use, although more expensive.
  • Chrome-plated brass: Used in high-end installations or spas.
• As for finishes, you can find nozzles in white, gray, beige, anthracite and other colors to match the pool environment.

• Fixed nozzles: They have a single water outlet direction, which simplifies their use and maintenance.
• Adjustable or adjustable nozzles: They allow adjusting the direction and, sometimes, the flow rate of the jet.
• They are useful for optimizing circulation, cleaning specific areas or creating massage effects in certain areas.
• If you are looking for flexibility in circulation or have cleaning problem areas, adjustable nozzles are a good choice.

• The number of nozzles depends on the size and shape of the pool
  • Small pools (up to 30 m³): two nozzles are usually sufficient.
  • Medium pools (30-50 m³): Two or three nozzles are recommended.
  • Large pools (over 50 m³): May require more than three nozzles, well distributed.
• The distribution should favor the movement of water towards the skimmers and avoid stagnation areas.
• In pools with irregular shapes, it is advisable to place nozzles in the areas less favored by the current.

• Installation: On new pools, installation is done during construction or assembly.
• On existing pools, it may require construction or adapters. The nozzles are usually installed in bulkheads or directly on the wall, and many can be easily screwed or glued.
• Maintenance: They usually require only occasional cleaning to prevent clogging by dirt or limescale.
• Some allow the front to be removed for cleaning the interior.
• Choosing nozzles that are easy to access and have spare parts available facilitates long-term maintenance.
• does it comply with safety and quality standards?
  • Nozzles must be made of materials resistant to pool chemicals and comply with safety regulations, especially in public or community pools.
  • It is advisable to choose products from recognized manufacturers and, if necessary, ask for quality or conformity certificates.
