Product Information
Full details
The Primaflow Vsp Poly Stopcock (P25 x 22mm) is an essential plumbing component designed for professional contractors and DIY enthusiasts who need a reliable way to control water flow in residential or commercial water systems. This stopcock provides the key benefit of a secure, leak-proof shut-off mechanism that is fully WRAS approved, ensuring safety for potable water use. One caveat is that users must ensure their existing pipework matches the specific 25mm to 22mm transition requirements, as mismatching pipe sizes will result in improper sealing.

Extended Product Information
FAQs
Is this stopcock safe for drinking water?
Yes, this product is fully WRAS approved, meaning it meets the necessary standards for use with potable (drinking) water.
Can this be installed in a horizontal or vertical pipe?
Yes, the valve can be installed in any orientation that allows for easy access to the shut-off handle.
Does this require any special lubricant during installation?
Generally, no. However, ensure the pipe ends are clean and free of debris to ensure a smooth seal.
What is the primary material of the stopcock?
The stopcock is constructed from high-quality, durable plumbing-grade materials designed for water system integrity.
How often should I service the stopcock?
It is good practice to turn the valve fully open and closed twice a year to ensure the internal seal remains free and functional.
Troubleshooting
Visible leak at the pipe connection
Ensure the pipe is inserted fully into the stopcock and check that the nut is tightened securely. Verify the pipe end has been deburred correctly.
Valve handle is stiff or difficult to turn
This is often caused by mineral buildup. Ensure the water system is turned off, inspect for debris, and operate the handle fully open and closed several times to clear the mechanism.
Incompatible connection
Verify that the pipe diameter matches the P25 x 22mm specification. Use a caliper to check the pipe if you are unsure of the outer diameter.
Pros and Cons
Pros
- Fully compliant with EN1213 and WRAS standards
- Compact form factor is ideal for tight spaces
- Suitable for both residential and commercial plumbing
- Designed for high-reliability in potable water systems
Cons
- Requires specific 25mm and 22mm piping compatibility
- Not intended for non-standard pipe diameters
- Manual shut-off requires physical access to the valve
Setup, Compatibility & Care
Installation requires standard plumbing tools to ensure a tight connection between the 25mm poly pipe and the 22mm side. Always ensure the pipe ends are cut square and deburred to prevent damage to the internal seals during insertion. When installing, tighten the connections to the manufacturer’s recommended torque to prevent leaks while avoiding over-tightening, which can stress the valve body. For long-term care, it is recommended to operate the stopcock valve at least once every six months; this prevents mineral deposit build-up (calcification) which can cause the internal mechanism to seize over time.
