16mm Non Return Valve

13mm Non Return Valve

• Great for DIY irrigation systems
• Use with 13mm Supply line

Hints & Tips:

• Build a fail safe irrigation system. Use a pump at both ends of irrigation line. Setup timers so as the pumps work at seperate times. Install Non Return Valves at both ends just after each pump to stop nutrient draining through opposite pump. If either pump fails then you have the other pump as a back-up.
