4″ Tee (Pressure PVC-U)

Split a 4″ pressure line without compromising strength. The 4″ Tee (Pressure PVC-U) is an equal solvent weld tee built for large-diameter, pump-fed pond systems where high flow and structural reliability matter.

When you’re running 4″ pipework, you’re typically feeding bottom drains, drum filters or high-volume returns. This fitting keeps the system solid while allowing a clean branch.

Why it’s a dependable choice

• Made for 4″ pressure PVC-U pipe
• Three solvent weld sockets for a permanent, watertight seal
• Suitable for pump-fed systems under pressure
• Designed for large, high-flow installations

Where it fits in your system

Typical uses include:

• Splitting a 4″ bottom drain line
• Creating a manifold on a high-flow return
• Adding a secondary feed in large pond builds

Always use pressure-rated fittings on pumped systems. Standard waste fittings are not designed to handle operating pressure.

Installation notes

• Clean all pipe ends and sockets with PVC pipe cleaner
• Apply suitable solvent cement for pressure PVC-U
• Insert fully with a slight twist and hold briefly
• Allow full curing time before restarting your pump

Work in a well-ventilated area and follow adhesive safety instructions.

In large pipework, strength is everything. Glue it correctly once and your 4″ pressure system stays secure, stable and leak-free.
