Product Information
Full details
The Plumbright T-Bar Ball Valve (15mm) is an essential component for DIYers and professional plumbers looking to manage cold water flow with precision. Its primary benefit is the full-bore design that minimizes flow restriction, making it ideal for high-demand applications, though users should note it is specifically engineered for cold water systems and should not be used for high-temperature hot water lines.

FAQs
Can this valve be used on hot water pipes?
No, this specific model is designed for cold water supply lines.
Do I need to use PTFE tape on compression joints?
Compression joints seal via the olive against the pipe and body; PTFE tape is generally not required for the threads themselves.
Is this a full-bore valve?
Yes, it features a full-bore design which ensures high flow rates with minimal pressure loss.
What tools are required for installation?
You will need two adjustable wrenches (spanners) and a pipe cutter or hacksaw.
Can it be installed horizontally and vertically?
Yes, the valve can be installed in any orientation as long as the flow direction is consistent with the valve's requirements.
Troubleshooting
Water leaking at the compression joint
Tighten the nut by another quarter turn. If the leak persists, disassemble and inspect the olive for damage or ensure the pipe end is not distorted.
Valve is difficult to turn
Mineral buildup may be present; gently work the valve back and forth to loosen sediment or inspect for internal obstruction.
Pros and Cons
Pros
- High flow rate due to full-bore design
- T-bar handle allows for easy operation in confined areas
- Simple compression fitting installation requires no soldering
- Robust construction for reliable shut-off
Cons
- Not rated for high-temperature hot water applications
- Compression fittings require specific pipe sizing to prevent leaks
- T-bar handle may be slightly larger than lever handles in very narrow wall cavities
Setup, Compatibility & Care
To install, ensure your 15mm copper pipe is cut square and deburred to prevent damage to the internal olive. Slide the nut and olive onto the pipe, insert the pipe fully into the valve body, and tighten the compression nut using two adjustable spanners—one to hold the valve body and one to turn the nut. Avoid overtightening to prevent cracking the olive or damaging the valve threads. Regularly cycle the valve once every few months to ensure the ball seat does not build up mineral deposits, which helps maintain smooth operation over time.
