The Primaflow Brass Stopcock is an essential plumbing component for homeowners and trade professionals who need a reliable way to isolate water flow to specific sections of a property. Its primary benefit is enabling targeted maintenance or repair work without requiring a full system drain, making it a critical tool for home plumbing efficiency. However, users should note that as a threaded brass fitting, it requires appropriate pipe sealant or PTFE tape to ensure a leak-proof connection during installation.

This unit typically relies on threaded sealant or PTFE tape for a leak-proof connection rather than internal washers.
Yes, the brass construction is suitable for both hot and cold water applications within standard residential plumbing systems.
The stopcock features 1-inch Female BSP (British Standard Pipe) parallel threads.
Yes, it can be installed in any orientation provided there is adequate clearance to turn the handle.
While brass is durable, it should be protected from freezing conditions if installed outdoors.
Shut off the supply, remove the fitting, re-apply a fresh layer of PTFE tape, and ensure the joint is tightened securely.
Apply a small amount of plumbers' silicone grease to the valve stem or operate the handle back and forth several times to break down mineral scale.
Installation requires standard plumbing tools, including an adjustable spanner and high-quality PTFE thread seal tape. To install, apply sufficient PTFE tape to the male-threaded pipe ends, then tighten the brass stopcock onto the pipes using your spanner. Ensure the valve is oriented correctly relative to the water flow direction if marked. For ongoing care, operate the valve at least once every six months to prevent mineral deposit buildup, which can cause valves to seize. Avoid using excessive force when opening or closing; a firm hand-tight motion is usually sufficient to seat the valve mechanism correctly.
