HydroSure Non-Return Check Valve - Gold - 3/4" BSP Female

A non-return valve, also known as a check valve, allows fluid (in this case, water) to flow in only one direction. It automatically prevents flow in the opposite direction.

This valve is designed for general use with pumps and suction hoses. For high-pressure applications beyond typical pump outputs, consult the product specifications or a professional.

Most non-return valves have an arrow cast or printed on the body indicating the direction of normal water flow. Install the valve so the arrow points in the direction you want the water to flow.

BSP stands for British Standard Pipe. It is a set of standardized, interchangeable pipe threads used widely in plumbing and mechanical applications.

This valve is specifically designed for water. Using it with other fluids may affect its performance and longevity due to material compatibility or viscosity.

Cleaning frequency depends on water quality and usage. If you notice reduced flow or backflow issues, it's a good time to inspect and clean the valve.

Check for debris lodged in the valve seat or on the spring mechanism. Ensure the valve is installed in the correct flow direction. Inspect the sealing surfaces for damage.

Verify the valve is not installed backward. Ensure the spring mechanism is not overly stiff or obstructed. Check for any other restrictions in the plumbing line.

Ensure the male BSP fitting is clean and properly threaded into the female valve port. Use thread sealant tape (PTFE tape) on the male threads for a secure, leak-free seal.
