5 FAQs of NPT/BSP Brass In-Line Vertical Check Valve, Female Thread One Way Backflow Preventer Brass Spring Check Valve

What does this check valve do?
It stops water or air from flowing backward. Water flows one way through the valve. The valve shuts automatically if flow tries to reverse. This protects your pipes and equipment.

Which way should I install it?
Install it vertically. The flow arrow on the valve body must point up. This ensures gravity helps the valve close properly. Wrong installation causes leaks or failure.

What pressure can it handle?
It works with water pressure under 16 bar (about 232 PSI). Brass construction makes it strong. Use it only within this pressure range. Higher pressure damages the valve.

Does it need maintenance?
Normally, no regular upkeep is needed. The brass body and spring are durable. It rarely fails if installed correctly. Debris in the line might cause problems sometimes.

Why might it leak?
Leaks happen for a few reasons. Dirt or small particles trapped inside stop the valve sealing. Damage to the metal disc or spring inside is another cause. Installing it sideways or backwards also leads to leaks. Check for debris first.
