Waterway 6727140 (672-7140) 4-Port Flow-Thru Manifold – 2" Slip x 2" Spigot x (4) 3/4" Ribbed Barbs
The Waterway 6727140 (commonly shown as 672-7140) is a flow-thru plumbing manifold used on many pool and spa systems to distribute water from a main line into multiple smaller lines. It features a 2" slip connection on one end, a 2" spigot connection on the other end, and four 3/4" ribbed barb outlets for hose/tubing connections.
Key Specifications
- Manufacturer: Waterway
- Part Number: 6727140 (672-7140)
- Manifold Type: Flow-thru (inline) distribution manifold
- Main Line Connections: 2" Slip (socket) x 2" Spigot (spg)
- Outlet Ports: (4) 3/4" Ribbed Barb
- Outlet Style: Barb (for flexible tubing/hose with clamps)
- Material: PVC-style molded fitting (spa/pool plumbing)
Common Applications
- Hot tub and spa plumbing where one 2" line feeds multiple 3/4" lines (jets, returns, features, or branch circuits)
- Pool/spa equipment pads where a compact distribution point is needed
- Replacement for cracked or leaking multi-port manifolds in molded plumbing assemblies
What This Manifold Does
- Splits flow from a main 2" line into up to four 3/4" branch lines.
- Maintains a straight-through main path while providing side outlets for distributed plumbing.
- Helps simplify layout and reduce the number of separate tees and fittings.
Fitment & Ordering Notes
- Confirm end style: one end is a 2" slip socket (pipe glues inside), the other end is a 2" spigot (glues into a 2" fitting).
- Confirm outlet size: outlets are 3/4" ribbed barbs intended for flexible tubing/hose with clamps.
- If your system uses a different outlet style (slip ports instead of barbs) or a different main size, choose the correct manifold variant.
When to Replace
- Cracks, splits, or pinhole leaks at the body or barb ports
- Loose or deformed barbs that won’t hold tubing securely
- Persistent seepage after re-clamping and trimming/reseating tubing
- Freeze damage or stress cracks from misaligned plumbing
Installation Notes
- Dry-fit first to confirm orientation and clearance for all four outlets.
- Use the correct PVC primer/cement for the 2" slip and 2" spigot glue joints.
- For 3/4" barb outlets, slide tubing fully to the barb stop (if present) and secure with properly sized hose clamps.
- Avoid over-tightening clamps, which can cut into tubing or crack fittings over time.
- Support plumbing to prevent vibration and pipe stress from loading the manifold.

Maintenance Tip
If a barb connection seeps, shut the system down and inspect the tubing end for stretching or splits. Cutting off 1/2"–1" of tubing and reseating it fully on the barb (with a fresh clamp position) often restores a reliable seal—especially on older, heat-softened spa hose.
