Product Information
Full details
The Plumbright Full Flow Straight Isolating Valve (Q70128) is an essential component for professional plumbers and DIY homeowners who need reliable water control in 22mm plumbing systems. It offers the key benefit of full-bore flow, minimizing pressure loss throughout your pipework while allowing for quick isolation during maintenance; however, users should note it is designed specifically for 22mm pipe diameters and requires appropriate compression fittings for installation.

FAQs
Can this valve be used for gas lines?
No, this valve is designed for water plumbing systems and is not rated for gas applications.
Is this valve suitable for high-pressure systems?
Yes, it is designed for robust 22mm plumbing infrastructure, but always check your system pressure limits against the product specifications.
Does it come with olives and nuts?
The valve is designed for standard compression fitting, which typically includes the nuts and olives required for connection to 22mm pipe.
Can I install this vertically or horizontally?
The valve is designed to be installed in any orientation that allows for easy access to the handle for isolation purposes.
What does 'Full Flow' mean?
Full flow means the internal bore of the ball valve is approximately the same size as the internal diameter of the pipe, ensuring there is no reduction in water volume.
Troubleshooting
Water leaking from the nut connection
Ensure the pipe is cut square and properly deburred. Tighten the nut an additional quarter turn, but do not exceed the recommended torque.
Valve handle is difficult to turn
Apply a small amount of plumber-grade silicone grease to the valve stem and cycle the handle several times to distribute the lubricant.
Pros and Cons
Pros
- Minimizes flow restriction due to full-bore design
- High-quality, durable nickel-plated finish
- Reliable isolation for maintenance tasks
- Ideal for 22mm heavy-duty pipework
Cons
- Not compatible with 15mm pipework without adapters
- Requires compression tool skills for proper installation
- Heavy-duty construction requires ample space for mounting
Setup, Compatibility & Care
To install, ensure the 22mm pipe ends are cut square and deburred to prevent damage to the internal compression olives. Insert the pipe into the valve and tighten the compression nut by hand before using a spanner to secure the seal. Do not overtighten, as this may deform the olive or damage the valve body. Periodically check for signs of dampness around the spindle or nuts during routine maintenance. If the valve becomes stiff after long periods of inactivity, a small amount of silicone lubricant applied to the spindle can assist in smooth operation. Avoid using aggressive chemicals when cleaning the exterior; a simple wipe with a dry or slightly damp cloth is sufficient to maintain the nickel finish.
