No more pump sucking

Forgot to mention that I changed my irrigation setting a few weeks ago. The pump was running too long per watering and the basin would get very low and the pump would make a sucking noise. So I timed the watering until the pump made a noise and used that for my baseline. I think I went from watering about 4 times a day for 8 minutes to watering 7 times (every 2 hours) a day 2 minutes per watering. Not very scientific but it hasn't affected the plants at all and now I don't have to hear the pump sucking. Bear in mind that the actual water volume probably hasn't changed much because when the basin got low the water volume being sucked up was greatly reduced.
