Applying a check-valve
By applying an in-line check valve between the piping and the nozzle, dripping can be eliminated completely. In addition, the check-valve enables a more responsive spray-start by filling liquid up to just before the nozzle. Watch the movie below to further understand how it works (English subtitles are available).
How does the check-valve work?
A check-valve is designed to only allow water to flow in one direction. The check-valve will open at a minimum pressure and reseal again once the pressure wears off. The check valve works due to a spring-design. The spring creates a force that pushes the valve into a closed position, preventing water from passing through. Once the system is turned on again and the pressure exceeds the spring’s resistance, it pushes the valve open, allowing water to flow through the nozzle and spray out.
Is my spray nozzle dripping because it’s damaged?
Before you invest in a check-valve it might be considerable to check whether your spray nozzle is worn out and needs replacement. A damaged orifice with a bent shape could also cause dripping. In addition, if the spray pattern has changed due to nozzle wear, the jet may hit the nozzle body and cause dripping. You can read more about how to detect spray nozzle failures:
