The Primaflow 22mm Lockshield Stopcock is designed for professional plumbers and DIYers who need a reliable method to isolate water flow within a 22mm plumbing system. Its primary benefit is the ability to shut off water to specific branches or the main supply for repairs, preventing the need to drain an entire system. A key caveat is that the 'lockshield' design requires a specific tool to operate, making it unsuitable for quick, emergency manual shut-offs where a standard handle valve might be preferred.
