My irrigation nozzles in the garden keep dripping, even when the pump is switched off?

I have an irrigation system in my garden which uses the water on a water butt. The pump is on a timer, but when its switched off, the drippers carry on dripping?? The flow is very small but its soaking the soil too much! Its some sort of syphon effect happening, because if i raise the drippers the flow stops.





How can i stop this from happening?





thank you!

That's impossible. Try raising the drippers.
Reply:.you need to install a vacuum brake in the line,or a shut off valve .what is happening is when the pump shuts down the line is full of water and it will keep siphoning the water just like if you were siphoning gas out of you gas tank.it will keep going until you brake the vacuum
Reply:if you didnt grease any of the seals that is why, most manufacturers recommend greasing the seals with vasoline/petrolium jelly to create a better seal.
Reply:Still water in the line. Put a shut off valve in at the beginning of the drip line.
Reply:This happened to me. It is likely a problem with the water pressure. Either find the valve and tighten it or get a plumber to come out and do it
