Product Information

Full details

The Plumbright T-bar ball valve is designed for professional plumbers and DIY enthusiasts needing a reliable flow control solution for 28mm cold water supply systems. Its primary benefit is the full-bore design, which minimizes resistance and ensures maximum water pressure, though users should note that the T-handle design requires adequate clearance space to operate effectively compared to traditional lever valves.

FAQs

Can this valve be used on hot water pipes?

This specific Plumbright T-bar ball valve is primarily designed for cold water supply systems.

Does this valve require pipe sealant or tape?

Compression joints are designed to seal via the olive and nut; pipe dope or PTFE tape is generally not required and can potentially interfere with the compression seal.

What is a full bore valve?

A full bore valve has an internal opening that is the same size as the pipe, meaning there is no restriction to the water flow when the valve is fully open.

Can I install this on plastic pipe?

Yes, provided you use an appropriate pipe insert inside the plastic pipe to maintain its structural integrity when tightening the compression fitting.

What does the T-handle represent?

The T-handle is the mechanism used to turn the internal ball. When the handle is parallel to the pipe, the valve is open; when it is perpendicular, the valve is closed.

Troubleshooting

Minor weeping at the compression joint

Ensure the pipe is cut perfectly square and tighten the compression nut an additional quarter turn.

Handle is stiff or difficult to turn

Check for mineral deposits or debris inside the valve; cycle the handle back and forth several times to break up minor scale buildup.

Pros and Cons

Pros

  • Full-bore design maintains maximum flow capacity
  • Compression fittings allow for fast, leak-free installation
  • Easy-to-grip T-handle for quick quarter-turn shut-off
  • High-visibility handle for immediate system identification
  • Compatible with standard 28mm plumbing pipework

Cons

  • Requires more physical clearance space than a slim lever handle
  • Designed specifically for cold water systems
  • Compression nuts require periodic checking in vibration-prone areas

Setup, Compatibility & Care

To install this valve, ensure the 28mm pipe is cut square and deburred to prevent damage to the internal compression olives. Slide the compression nut and olive onto the pipe, insert the pipe fully into the valve body, and tighten the nut. Do not overtighten, as this may distort the olive. This valve is intended for use with cold water systems only; avoid exposure to high temperatures or corrosive chemicals. Periodically exercise the valve by closing and opening it fully at least once every six months to prevent mineral deposit buildup (calcification) around the ball seal.
