Fit the valve in the supply line to match the pipe size and the pressure of your system: a low-pressure valve for a low-pressure system, the high-pressure (TNL) valve for a high-pressure line. Follow the instructions supplied for which way round it goes.
For other pipe joints see our fittings and supply pipe.
Questions
Which anti-syphon valve do I need?
Match the pipe size (16 mm or 25 mm) and the pressure of your system. There are two low-pressure sizes and one 16 mm high-pressure version.
What does an anti-syphon valve do?
It stops water being drawn back or siphoning through the line when the flow stops, so a tank or pipe run does not drain itself.
