Product details

The Hayward SP1421D is an Insider HydroStream return fitting with a 3/4 inch rotating eyeball. It fits into a 1-1/2 inch PVC pipe and finishes the return in white.

What a HydroStream does

A return fitting is not just a cover for the end of the pipe. The size of the opening sets the speed of the water leaving it, and a HydroStream narrows the outlet so the stream carries further into the pool. Aim a pair of them well and the surface keeps moving toward the skimmer instead of stalling in the corners.

Aiming and locking

The 3/4 inch eyeball rotates so you can point the stream down to stir the bottom or across the surface to sweep floating debris. Once it is where you want it, the outside locking ring holds it there instead of letting flow push it back out of position.

Related sizes

Hayward lists a 1 inch Insider HydroStream and a large body 3/4 inch version under separate part numbers if this one is not the size you are replacing.

Questions and answers

What people ask about this product, answered by our pool techs.

What pipe does this fit?
It fits into a 1-1/2 inch PVC pipe.
Can I aim the return?
Yes. The 3/4 inch eyeball rotates, and the outside locking ring holds it wherever you set it.
What is the difference between this and the 1 in version?
This one has the 3/4 inch eyeball opening. Hayward also lists a 1 inch Insider HydroStream, and a large body version of the 3/4 inch, as separate part numbers.
Why would I use a HydroStream instead of a plain eyeball?
The narrower opening speeds up the return stream, which helps drive circulation across the surface toward the skimmer.
