Prestwich Hydroponics® 13mm Barbed Non-Return Valve – 6918836748373

A 13mm non-return valve, also known as a check valve, is a type of valve that allows water to flow in one direction and prevents it from flowing back in the opposite direction. It is commonly used in irrigation systems, especially those with a water pump, to prevent water from flowing back into the pump when it is turned off.

The 13mm non-return valve is designed with a barbed end, which allows it to be easily installed into 13mm irrigation tubing. It is a small but important component of an irrigation system that helps to ensure that plants receive a consistent and reliable water supply. By preventing water from flowing back into the pump, it helps to prevent airlocks in the irrigation pipe, which can disrupt the flow of water and damage the pump.

Using a 13mm non-return valve can also help to improve the efficiency of an irrigation system by ensuring that water is not wasted due to backflow or leaks. It is a simple and cost-effective solution that can provide peace of mind and help to keep your plants healthy and well-nourished.
