The Primaflow 15mm Ball Valve is designed for professional plumbers and DIY enthusiasts who require a reliable and efficient way to control water flow in residential plumbing systems. Its primary benefit is the full-bore design, which minimizes resistance and ensures maximum throughput, though users should be mindful that it requires proper compression fitting techniques to ensure a completely watertight seal.

No, this valve is designed specifically for water plumbing systems and is not rated for gas applications.
Yes, the product includes both a red and a blue butterfly handle for easy identification of hot and cold supply lines.
You only need standard plumbing tools like a pipe cutter and two adjustable wrenches to tighten the compression nuts.
Yes, the compression fitting set includes the necessary nut and olive for a standard 15mm copper pipe connection.
If using with plastic piping, you must use a suitable pipe insert to maintain the structural integrity required for the compression olive to seal correctly.
Ensure the pipe end is square and free of burrs. Tighten the compression nut slightly more, or replace the compression olive if it has been deformed.
Check for debris accumulation or limescale buildup. Flush the system or gently work the valve back and forth to loosen sediment.
Verify that the valve is in the fully open position; the handle should be parallel to the pipe. Check for partial blockages in the supply line.
To install, ensure the pipe end is cut square and deburred to prevent damage to the internal olive. Slide the compression nut and olive onto the pipe before inserting the pipe into the valve body. Tighten the nut by hand, then use an adjustable wrench to tighten it by an additional half-to-three-quarters of a turn. Avoid over-tightening, as this can crush the olive and deform the pipe. For maintenance, periodically cycle the valve from open to closed to prevent the build-up of limescale or mineral deposits that could cause the mechanism to seize. If the valve becomes stiff, check for debris or sediment trapped within the flow path.
