Hi,

I have fitted a pump to our water butt and hooked it up to a micro
irrigation system. However when the pump is turned off, the first dripper
keeps on flowing due to the syphone effect I guess.

Are there any ways to easily fix this ?

Found this on the web which looks the same problem as me, but doesn't
specify the solution.

"...it has no anti-syphon protection so if you use a standard watering
kit with this, it will syphon your tank dry overnight unless you put in
an air-stop hole with a bit of watering tube..."


put in an
air-stop hole with a bit of watering tube..."

Is the solution.
