Return Jet
Return jets are the fittings in a pool wall through which filtered and treated water is returned to the pool.
Definition
Return jets are the fittings in a pool wall through which filtered and treated water is returned to the pool.
Typical Values: Typically angled 45° toward the surface and directed to create clockwise pool circulation
In Plain Language
Return jets direct treated water back into the pool, creating circulation that distributes sanitiser and temperature throughout the pool. They should be angled to create a circular current pattern that maximises mixing. Adjustable return jet fittings allow direction control. In pools with poor circulation spots (corners, areas away from returns), algae and sediment tend to accumulate — adjusting return jet angles can improve these areas.
Why It Matters
Return jet positioning affects chemical distribution and circulation dead zones, which are algae-prone areas.
Typical Values
Typically angled 45° toward the surface and directed to create clockwise pool circulation
