My Ballast System

[xpjim1]

The reversible pumps will not allow water through. The aerators are faster. I talked to the guys at make a wake and for what I am planning the fill times would be about 19 minutes. With the aerators I should be about 8 minutes. We will see!!!

Here is the answer to the gate valve switch:

GM uses a latching timer relay with a momemtary switch for their rear defrost sys. the timer will power the gatevalve long enough to fill the bags and then de-energize. Does anyone know if these g/valves are self closing?

That's similar, but a different type (the type I would use actually). The RV style xpjim has opens and stays, or closes and stays. It has a reversible motor that creates a latch when it has input. Once it is open the latch breaks so the motor stops turning, but the gate stays put. No coils in it to return it. Same process for closing.

The GM type for the defroster is not a permanent latch, but has a timer on it, so the latch is broken after x seconds, and then closes again. You can create a latching circuit like this with 3 relays farily easily. This one would have a coil to return it to its normal position after the latch is broken.

No the RV gate valves require an action to close also.

I will definately be contacting you in the future. Thanks for the info. I still hate electricity though. Ever since I worked in a restaurant. I was cleaning a walk in freezer, I took a wet brillo pad over a broken light socket exposed wiring. I definately felt the power. I was smokin!!!.

So you bought aerators or reversibles?

[xpjim1]

I bought the aerators. 6 Tsunami's 1200 GPH

[spharis]

And do you plan on wiring them as loops (both posi and negative from each switch), or by using relays and a trigger?

[chpthril]

I bought the aerators. 6 Tsunami's 1200 GPH

which cost more: 1 reversible (+ check valve(s)) or 2 aerators?

I saw 2 aerators for less than 1 rev but dont know how the flow rate compared as one was in GPH and the other in GPM and I didn't do the math.

Someone had posted questions about these before, and I asked him some troubleshooting info about them. Those are a whole 'nother can o worms, but they can be made to work too, although you so not have enough free banks.

Yes, I agree. That is why I will probably not mount my switches on the dash. BTW, it was me that was asking before. I have one free switch and I plan on hooking up my tower lights to that If I can get it figured out.

Thanks!

Not Sure I am waiting for someone to send me another document that did not use relays but tied all the grounds. Not sure what that means but i think it had 6 power wires from the switches (1 to each pump) and 1 negative from the switches which all pumps were tied into. This is for the ballast pumps only as they do not have a gate valve. On the switches the negatives were all joined. Hope that makes sense.

I want to do what will work, is easy and not screw with the boats electrical. I just do not know enough here.

Back to work. I will post the other document tonight. have to get back to work

1 tsunami 1200 gph is $30, the ignition protected reversible is about $200. it is about 560 gph. You can get non ignition protected for less.

Yah, I dont want a permanent latch, I want to energize the gate long enough to open it with out having to hold a momentary, or turn on/off a toggle.

I think 2 timer relays will work, 1 to open when a fill is turned on, and 1 to close gate when fill pump is turned off. In other words, an "automatic" gate valve.

See my say

Or you could just have it tied to the pump switch so it was open when the pump was on, and closed when the pump was off.

The gate valve takes only 2 seconds to open or close.

If you have the fill pumps mounted by the enginge, just attach the ground wires to the block and run the hot to the switches.
