Product Information
Full details
The Plumbright 22mm Isolating Valve (Q70122) is an essential component for residential and commercial plumbing systems, designed for homeowners and professional tradespeople who need a reliable way to shut off water flow to specific fixtures. Its primary benefit is the ability to perform maintenance or repairs on a single sink, toilet, or appliance without needing to drain the entire building's water system. However, users should be aware that this specific model requires appropriate 22mm pipework and should be installed by a competent person to ensure a permanent, leak-free seal.

FAQs
Can I use this on 15mm pipes?
No, this valve is specifically designed for 22mm pipework. You would need a 15mm variant for smaller pipes.
Do I need PTFE tape for this installation?
Compression valves typically do not require PTFE tape on the olives, as the mechanical compression creates the seal.
Is this valve suitable for central heating systems?
Yes, it can be used in heating applications provided it is within the rated temperature and pressure specifications.
How do I know if the water is off?
When the slot on the valve stem is perpendicular to the pipe, the water is turned off. When parallel, it is on.
Should I install this valve horizontally or vertically?
It can be installed in either orientation, provided the flow direction arrow points in the direction of the water supply.
Troubleshooting
Small drip coming from the compression nut
Gently tighten the nut a quarter-turn further to compress the olive onto the pipe.
Valve is difficult to turn
Apply a small amount of silicone-based plumbing grease and work the valve back and forth to clear debris or light scale.
Water continues to flow after turning the valve off
Verify the valve was turned fully 90 degrees; if it persists, the internal seal may be damaged and require unit replacement.
Pros and Cons
Pros
- Simplifies routine maintenance and emergency repairs
- Sturdy construction ensures long-term reliability
- Easy to operate without specialized tools
- Helps prevent water waste during minor plumbing leaks
Cons
- Requires proper compression fitting knowledge
- Not compatible with smaller 15mm piping without adapters
- Manual shut-off handle can become stiff if not operated periodically
Setup, Compatibility & Care
Installation should be performed on a clean, cut-to-length 22mm pipe. Ensure the pipe end is deburred to prevent damage to the valve's internal seal.
- Ensure the water supply is drained before cutting the pipe.
- Slide the compression nuts and olives onto the pipe.
- Position the valve, ensuring the flow direction arrow matches the water flow.
- Tighten the nuts using an adjustable spanner, being careful not to over-torque the fitting.
For care, periodically turn the valve on and off once or twice a year. This prevents the internal mechanisms from seizing up due to limescale build-up, ensuring the valve remains functional when you eventually need it.
