Product Description

Elevate the aesthetics of your pool deck and create captivating water features with the Jandy 2-1/2" Deck Jet (SKU: JDJ2004, UPC: 052337075671). This elegant, low-profile jet delivers a clear, smooth arc of water from the deck surface directly into your swimming pool or spa, adding a mesmerizing visual and acoustic element to your backyard oasis. 

Key Features & Benefits:

  • Aesthetic Enhancement: Creates a beautiful, arcing water feature that adds movement, sound, and a resort-like feel to any pool design.
  • Low-Profile Design: Sits nearly flush with the deck surface, minimizing tripping hazards and maintaining a clean, unobtrusive look when not in use.
  • Adjustable Flow & Direction: Easily adjust both the direction (up to 360 degrees) and the water flow volume/height using a standard adjustment tool (or flathead screwdriver), allowing for customizable water effects.
  • Durable Materials: Constructed from high-quality, corrosion-resistant UV-resistant plastic (color: gray body/white cap) designed to withstand the harsh pool environment and sun exposure.
  • Easy Installation: Designed for simple installation in concrete decks and suitable for new construction or major renovations.
  • Multiple Jet Options: This model includes different easy-to-change orifices to vary the height and width of the water arc to perfectly suit your style.

Warnings and Disclaimers

  • Professional Installation: Installation must be performed by a contractor licensed in pool equipment to ensure warranty compliance.
  • Pressure Limit: Do NOT connect to city water systems. High pressure (over 35 PSI) can rupture the jet housing.
  • No Tool Zone: Do NOT use pliers or wrenches to install the nozzle into the swivel base; it is designed to be pushed in by hand.
  • Testing Plug: Only use the provided pressure testing plug during initial construction phases.

Pro Tips

  • Balanced Flow: For multiple jets, use a [loop plumbing manifold](https://www.jandy.com) to ensure each nozzle receives equal water pressure for uniform stream heights.
  • Winterization: Remove the nozzle and swivel base, clear the line with air, and replace with the [pressure plug](https://www.eztestpools.com) to prevent winter freeze damage.
  • Height Sync: Set the jet body exactly flush with the expected finished deck surface (plaster, travertine, or concrete) to ensure the bronze plate sits flat.
  • Debris Management: If the stream begins to "flutter," unscrew the cover plate and pull the nozzle to clear out small grains of sand or debris that may have bypassed the filter.
