Black FlowStar® 3-Way Valve
Product Overview
Dual-dimension ports allow direct integration into either 1.5-inch pipe or 2-inch fittings without extra adapters.
The AquaStar AV3W15C FlowStar 3-way valve is engineered for suction or return side diversion, featuring dual 1.5-inch socket and 2-inch spigot ports. Its black UV-resistant composite body withstands prolonged sun exposure on outdoor equipment pads, while the internal diverter seal prevents bypass leaks between ports.

Benefits & What Makes It Different
Dual-Fit 1.5" Socket x 2" Spigot Ports
Glue 1.5-inch PVC pipe directly inside the socket or slip a 2-inch fitting over the spigot collar to fit tight manifold spaces.
UV-Stabilized Black Body
Resists outdoor solar degradation and exterior plumbing surface chalking across long service cycles on exposed equipment pads.
Positive-Seal Diverter Design
Internal seals create a firm water stop without requiring excessive turning torque on the manual handle.
Compatibility
- 1.5" Schedule 40 PVC pipe (glues into internal socket)
- 2" Schedule 40 PVC fittings (glues over external spigot)
- Standard motorized valve actuators with standard screw mounting patterns
When To Use This
Pro Tip
Always unbolt and remove the internal diverter assembly before gluing the valve body into your plumbing; stray PVC cement vapors can chemically tack the rubber seals to the interior casing wall.
Common Questions & Instructions
How do the 1.5-inch socket and 2-inch spigot dimensions work on this valve?
The ports accept 1.5-inch Schedule 40 PVC pipe glued directly into the interior socket, or 2-inch PVC couplings and fittings glued over the outside spigot diameter.
What are the common symptoms indicating this valve needs replacement?
Look for water weeping past the handle stem, air bubbles being drawn into the pump strainer basket from suction ports, or persistent internal bypass when a port is fully closed.
Can this AquaStar valve be installed on both suction and pressure lines?
Yes, the FlowStar valve is rated for full vacuum and pressure operations, making it suitable for skimmer/main drain suction manifolds or heater and return bypass lines.
