Nice video....first one that covers exactly what i am doing that i can understand. It would be very help full to know what contactor you are using?

[@marvidrunzthis]

I would love to see a tutorial on a 8 pin alternating relay for two pumps to share the load.

I think using 24 v for float switches is more safer then 110v , especially the float would be inside the water think , what d u think .

OH My Gosh - I love you - this is so awesome to learn - (I am having either float or contactor issues - old unit and the install in 2003 failed to 'insulate/weather stripping - on the bottom and sides of my electrical box - so TONS of corrosion. I cleaned to contacts, but still not functioning - the plumber came by tapped the contactor and it did kick on, drained my sewer drum, but still not auto working. This was so helpful. (I have replaced a contactor - single pole - on my A/C unit a few years back, so now I remember how that works - same as the pump floats!! THANK YOU!!!! You are a great teacher!

Hi, I've got a pentek P/N : 176L8223 and the drive doesn't restart after a power outage. Can you help me?

[@henokB]

This is very useful. I have been trying to figure out how to do a holding circuit.

[@RCworstwater]

Glad it was helpful!

Can we see another application by using a contactor with coil 24 v for the floats with power supply of 220v.

[@nickmarquez2024]

Is that a special type of contractor to have two terminals on each coil? Normally I just see an "A1" and "A2". I'm not sure I understand how the lower float switch is able to disrupt the coil from being energized if there is still voltage going from L2 to the coil due to the upper float still being in a closed position. I imagine you would also be able to replace the first float switch with a pressure switch that tells the pump to run whenever pressure drops below cut-in, but if the water level drops gets too close to a dry run situation, it could shut off the pump? Thanks for any feedback you can give, your videos are some of the best I've seen for learning to do this stuff when there really aren't any professionals in my very remote area to actually call out.

[@FreddyRodriguez-gl5xc]

Great video. You mentioned not the best way to do this. Can you comment on the best method to use?

[@jalilalmteen536]

Water tank ( correction )👆

[@brianmccollum2414]

Is there a way to do this with 3 phase?

[@bendien1798]

Nice one amigo.

Thanks!
