Product Information
Full details
The Xcel Home 22mm isolating valve is an essential plumbing component designed for professional plumbers and DIYers who need a reliable way to manage water flow in domestic and commercial systems. Its primary benefit is the ability to quickly isolate specific sections of pipework or individual appliances for maintenance without shutting off the main water supply to the entire building. The main caveat for users is that it is strictly designed for 22mm pipe diameters, requiring precise measurement of existing copper pipework before purchase.

FAQs
Is this valve suitable for central heating systems?
Yes, the brass construction is compatible with both hot and cold water systems, including standard central heating loops.
Do I need to use PTFE tape on the threads?
No, compression fittings create a seal using the compression olive; PTFE tape on the nut threads is unnecessary and may actually interfere with a proper seal.
Can I reuse the valve if I take it off the pipe?
It is generally recommended to replace the olive if the valve is removed, but the valve body itself can be reused if undamaged.
What is the pressure rating for this valve?
The valve is designed to withstand standard domestic and commercial water pressure levels, compliant with WRAS standards.
Can this be used on plastic pipe?
While intended for copper, it can be used on plastic pipe provided you use the correct pipe insert to prevent the pipe from crushing when the nut is tightened.
Troubleshooting
Joint is leaking after installation
Ensure the pipe is pushed fully into the valve body and try tightening the nut by another half-turn.
Valve handle is stiff
Apply a small amount of silicone-based plumbing grease to the spindle, or check that the valve is not under excessive tension from pipe misalignment.
Olive will not seal
Check that the pipe is not deformed or oval-shaped, and ensure the olive is correctly positioned and not damaged.
Pros and Cons
Pros
- Tool-free installation requiring no soldering
- WRAS-approved for regulatory peace of mind
- High-quality brass build for durability
- Essential for simplifying future maintenance tasks
Cons
- Only compatible with 22mm diameter piping
- Requires proper wrench technique to avoid over-tightening
- Not suitable for gas or chemical fluid lines
Setup, Compatibility & Care
To install, ensure the 22mm pipe end is clean, square, and free of burrs. Slide the nut and olive onto the pipe, insert the pipe fully into the valve body, and tighten the nut until firm. Do not use heat or jointing compound on compression fittings, as the olive creates the seal through mechanical pressure. For ongoing care, periodically check the valve for any signs of weeping around the nut. If a leak occurs, a quarter turn of the nut is usually sufficient to seat the olive. If you live in an area with extremely hard water, operate the valve handle twice a year to ensure the internal mechanism remains free-moving.
