Well pump Submerseible 3 wire- Feeding into storage tank With 2-wire 120 volt float and another 3 wire submersible in storage tank that then feeds Pressure tank.
In picture to the left he told me to intercept one of the Lines for the well pump, to the Float inside the Tank. I get that. Will turn the pump off when its full.
The 3-wire in the storage tank he told me to run straight to pressure tank...

I need another control correct since its a three wire- Star/run pump. He made it sound like everything is there. Normally I never do these the plumber does and I just run power to it so never though about it.
Unless He wants the motor to just only use either Run or Start. what he told me won't work. Since there not alot of pressure to feed the water from storage tank to pressure tank could he be thinking of just using Run winding??

There is one. But i only have one 3 wire controller. But 2 pumps are three Wire.
Here the pressure switch and the 2-3wire pump
The one three wire pump in the holding throwing me since there no way without controller to properly use the pump correct.

Most of the pressure switches I have seen have two sets of contacts but I have wired them using only 1 set and breaking only L1
 
I have two- three wire pumps. I think I still need another controller.
One in well that is controlled from float and one in reserve Tank that will be controlled from pressure tank.
 
Only way I can see it work is if I don’t use one of the winding in the three wire pump.
Basically wire it so it starts in run. That does not seem right. Hence I think I need another controller

I’ll draw it out I should of done that before opening mouth
 
Here is video that might prove helpful
As noted, I have wired them only breaking one line thru the switch.

Yes, two pumps two controllers. It is possible to have a submersible pump that only needs two wires, so you might want to confirm that. Pump guys run that black 3 wire plus ground everywhere

Okay that’s what I was wondering it looked like a factory whip but if he wired the whip in maybe he only need a two wire. Thanks for reassuring my idea
 
The control box consists of a potential relay and a start capacitor. When relay sees it's "pick up voltage" it opens the circuit to the start capacitor. It can only be used on an individual motor so if you truly have a three wire motor on both pumps you need two of said control boxes. The operating control, usually a pressure switch but maybe a float switch in some cases, normally connected ahead of this control box
 
If you had two pumps in parallel, you could possibly get away with one controller. But since the conditions for running each pump is independent of the other pump and both may need to run at the same time there is no way to avoid having two controllers.
If there were a free overflow pipe from the cistern back into the well, you could consider running both pumps whenever the pressure switch calls for flow. But it would not let you prefill the cistern to allow for water usage higher than the refill rate of the well.

Get your ohm meter out and confirm that both pumps require the third wire. Either of them may not. Depends on the pressure and/or lift.

Ya I thought about that lol as soon as someone mentioned that whip may not be factory. Lo and behold that is what happened.
Thanks for replying,
I should not have been so complacent. I should of none to check that before leaving
