Brass Single Non Return Check Valve 1/2(15MM) in BSPP

Use the Spring loaded check valve for tank systems to prevent backflow contamination.
These spring loaded check valves don't provide enough protection to be able to prevent backflow to mains water but they are perfect for tank systems that are linked with mains water.
Install a spring loaded check valve on a tank/mains system to prevent mains water filling up your water tanks illegally.
We know a lot of people like to use Spring Check Valves but we prefer Swing Check Valves because the have less tendency to block up.
