Product details

The Jandy R0515400 is the impeller screw with O-ring used across most of the Jandy pump line. It is a 1/4 inch by 20 screw, one inch long, with a reverse thread, and it ships with the O-ring that seals it.

Why the reverse thread matters

The impeller turns constantly while the pump runs. A conventional right hand thread in that position tends to back itself off, so Jandy specifies a left hand, reverse thread screw. That is the single reason a similar looking fastener from a hardware bin is not a substitute, and it is also why the screw comes off the opposite way to what most people expect.

When you need it

Anyone pulling an impeller for a seal change, a clog or a wear inspection is handling this screw, and it is common for the head to be chewed or the O-ring to be flattened by the time it comes out. Replacing both while the pump is open is cheap insurance against a leak path at the impeller.

Fitment

The screw covers the ePump and ePump Pro variable speed pumps, the FloPro and VS FloPro families, FloPro FHPM, WaterFall SWF, WaterFeature WFTR, Stealth SHPF and SHPM, and PlusHP PHPF and PHPM.

Questions and answers

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

Why is the thread reversed?
The impeller spins in one direction and a standard thread would work itself loose. Jandy specifies a reverse thread here, which is why a hardware store screw is not a substitute.
Does the O-ring come with it?
Yes. The part is supplied as one screw and one O-ring.
What size is the screw?
1/4 inch by 20 thread, one inch long, with a reverse thread.
Which Jandy pumps does it fit?
A broad range, including the ePump and ePump Pro variable speed pumps, FloPro and VS FloPro, FloPro FHPM, WaterFall SWF, WaterFeature WFTR, Stealth SHPF and SHPM, and PlusHP PHPF and PHPM.
