Just set up a coco run to waste system but when the pump turns off the drippers continue to drip and syphon the water barrel, any ideas on how to stop this? Cheers 👍🏼

Pump off but water continues to drip?

Low pressure check valve, drippers above the waterline will stop it. A siphon break at the high point of the line depending on pump

By Low pressure check valve do you mean something like this mate? This is the pump I'm using

By siphon break, do you mean something like using a T piece where the pump 13mm pipe comes out the top of the water barrel T it off there and run a blank pipe high so water doesn't flow out of it?

So the hose goes from the pump at the bottom of a barrel out the top? Prob the best way is to buy a PVC T and connect it at the top of the barrel. From there run another line to the drippers and add a pipe that goes up from the T like 2" pipe maybe a foot or 2 high and open. The weight of the water in that tube will allow the pump to force the water to the drippers when running and the water in that tube will rise a bit until the weight of the water becomes to much for the pump to push against. The water will follow the path of least resistance and at that point it will be the drippers. When the pump shuts off all water will follow gravity and drain from the T back into the res and drippers breaking the siphon.

Yep its pumped from the bottom of the barrel so I'll do that thank you :)

I just put a 90* elbow above the waterline in my res, then drilled a small hole on the underside of the elbow pointing back into the res. The loss of pressure is minimal and the hole allows air in the line when the pump shuts off.
