The Primaflow 15mm Gate Valve is an essential component for homeowners and tradespeople looking to control flow in low-pressure plumbing systems such as tank feeds or heating circuit branches. This economy-specification valve offers the key benefit of a full-bore design, which minimizes pressure loss by allowing the gate to lift entirely out of the waterway. While it is highly efficient for isolation purposes, users must note that it is designed strictly for binary operation—fully open or fully closed—and should never be used to regulate or throttle flow.

No. This valve is designed only for fully open or fully closed operation to prevent internal wear.
No, this is an economy-specification valve intended specifically for low-pressure systems.
You will need a pipe cutter and two adjustable wrenches to tighten the compression fittings.
Yes, it is suitable for tank feeds and heating circuit branches within its pressure rating.
Generally, gate valves are bi-directional, but it is best practice to install them such that the handle remains accessible for future maintenance.
Tighten the nut slightly more with an adjustable wrench. If it continues to leak, remove and check that the olive is not deformed and the pipe end is clean.
Ensure you are not over-tightening. If the valve has sat idle for a long time, try gently oscillating the handle to break up minor mineral deposits.
Check that the gate has fully retracted by turning the handle until it stops. If restriction persists, check for debris or blockages within the pipework near the valve.
To install this valve, ensure your 15mm copper or plastic pipe is cut square and deburred. Slide the compression nut and olive onto the pipe end, insert the pipe fully into the valve body, and tighten the nut by hand before finishing with a wrench to create a watertight seal. Ensure the valve is oriented correctly with the directional flow if marked. Regarding care, the most important rule is to operate the handle firmly to the stops. Never leave the valve in a partially open position, as the water pressure can cause the gate to vibrate or create turbulence that leads to premature damage of the seating mechanism.
