Well pump to sprinkler timer switch?

[Bryon Bullock]

Hi everyone.
Using an old well pump that sat dormant for 5 yrs - we're using it for irrigation purposes only. Our pump was installed in the 80's and has no pressure tank. I believe it has a pressure switch but a friend came over to check why it wouldn't turn on and said the switch was siezed, so he electrically bypassed the switch so we could test the pump manually. The pump still works great and puts out 15 GPM @ 30 PSI, with a 90 no-flow PSI.

I heard "they" make a stand-alone switch that will turn our well pump on/off in synchronization with a sprinkler timer (that is separate from the sprinkler timer). IE sprinkler timer kicks on the first cycle which then turns the pump on, sprinklers turn off, pump turns off.

Does anyone know what this is called?

Any info is appreciated, thank you.

You need a pump start relay. It's a definite purpose contactor with a 24volt coil. $40-100.

although these RIB relays are very nice and can be used for many things they need their own splice box and can be confusing to someone with limited electrical experience. I would use a purpose built pump start relay like this https://www.amazon.com/dp/B00FYRP68U/ref=cm_sw_r_cp_api_i_jPecFb81521EW
