"Smart" Swing Check Valves – Made by Magic Plastics
The Swing Check Valve provides you with reliable back-flow prevention without the inline restriction of a conventional check valve. With the use of high powered magnets, the “Smart” Check valve remains in the closed position to 2 PSI, opening fully when 2 lb. line pressure is exceeded.
Swing Check Valves limit the flow of water to one direction. This prevents water from flowing backwards or backing up into your pump or filter.
Swing Check Valves should be used only in areas under pressure where water is flowing upwards. All of our Swing Check Valves come with unions on them. We feel it is very important to have unions on your check valve just in case something gets stuck in it. These unions will allow you to remove the check valve without cutting into your plumbing.
