Switch question

[Dave K]

In regards to the diagram below can I wire in 2 switches to the same pump? This pump fills the intergrated bow sac and a second on-demand bag when required?

Yes, but why? If you do, i would probably install a diode in each switched 12V output to prevent it from back feeding to the other switch circuit. I need to study this more as well.

[Dave K]

For simplicity sake really. It would be clear and straight forward.

Rather than needing 3 switches: 1 on-off to fill, and 2 on-off for empty (2 bags) I just thought it would be a simpler way, 1 switch for each bag.

I was thinking of some kind of feed back issue but the power would be terminated at the "other switch" because it would be in the off position. Even if the switch was pushed on there is power going to the pump already from the 1st switch.

2 sacs filled with 1 pump,
2 empty pumps on intergrated sac
1 pump on tempoary sac

I guess I could just use 2 on-off-on switches and wire fill to the first switch only and use that switch to fill both bags

What kind of pumps are filling/draining the walkway sac?

The rule at the back fills both the intergrated and the second sac that will sit under bow cushion insert. That line is a 1" going to a manifold with 2 outlets both witha shut off.

The empty pump will be a Tsunami 800 for 2nd sac and 2 tsunamis for the intergrated.

Which leads me to ask should the 2 empty pumps on each leg of the intergrated sac have a separate switch

Ok, trying to understand the need for the 2 switches. Does the manifold just simply shut off flow to both sacs or does it divert the flow based on diverter position? Are you wanting to control each fill and drain circuit independently?

The manifold has 2 manual ball valves one going to each bag, not a diverter. I am wanting to fill 1 sac with 1 switch and a 2nd sac with a second switch.

Then I dont see a problem with it, looks good. You could do it with one switch, unless you wanted to have the ability to drain the front sacs separately.

Thanks Sir Mike !!!
