15mm Brass Single Check Valve - Hanicks - MSCV1500

Yes, this valve is WRAS approved, meaning it is certified for use in systems where water can come into contact with drinking water, ensuring it meets safety and quality standards.

While specific temperature limits are not detailed, brass valves of this type are generally suitable for standard hot and cold water applications found in domestic and heating systems. For extreme temperatures, consult Hanicks technical support.

The valve is designed to be installed in any orientation, but it is crucial to ensure the flow direction arrow correctly aligns with the direction of water flow in the pipe.

A single check valve is recommended when you need to prevent water from flowing backward in a pipe, which could contaminate the supply or damage equipment. Examples include preventing boiler water from flowing back into the mains supply or protecting pumps.

The valve is designed for low maintenance. Periodically inspect for leaks or damage. If performance issues arise, access to internal components is designed to be convenient for servicing or replacement.

Specific warranty information should be obtained from the retailer or Hanicks directly. Typically, manufacturers offer warranties on plumbing components against defects in materials and workmanship.

Yes, a check valve can be used in conjunction with a pressure reducing valve. It is often installed downstream of the PRV to prevent backflow into the mains supply and can also prevent backpressure from affecting the PRV's operation.

Ensure fittings are securely tightened. If using compression fittings, check that the olives are correctly seated. If using soldered fittings, ensure a proper solder joint has been made. Re-examine pipe preparation for any imperfections.

Verify the valve is installed in the correct flow direction (arrow pointing with flow). Check for any debris or obstructions within the valve by carefully disassembling (if possible and safe to do so) or flushing the system. Ensure no other components in the system are causing a restriction.

This could indicate water hammer or an issue with the internal sealing mechanism. Ensure the valve is correctly installed and not experiencing excessive pressure surges. If the noise persists, the valve may require servicing or replacement.

Confirm the valve is installed in the correct orientation. Check that the valve seat and disc are free from debris and sealing properly. If the valve has been in service for a long time, internal wear may be preventing a seal; consider replacement.
