New addition to ATO.
I've had this sitting around and finally got it hooked up.
It's an Avast diaphragm pump that does like 400ml/m along with another pressure switch that is wired for a controller switch input.
I also had a float valve hanging around and slapped that in too.
I have the tsunami at1 as an independent redundancy from the controller in case it fails. It is set slightly higher then the dual in line float switches and slightly under the sump high single float.
The dual float switches in series work together. One is on top of the other. If either floats up the circuit is opened. This has been in use for many years since around 2010.
The sump high single float switch is even older. It was part of the ato I setup in 2009 for my 55 gallon from auto top off.com or something like that. Its always out of the water. Or should be. If it opens then there's a big issue. This is used for my AWC and Lime dosing.
Then there's the new stuff. The avast pressure switch hooks up to the apex like the float switches. Its set slightly higher then the bottom of the dual in line floats and slightly lower or about the same as the second top dual float setup.
And for added measure the ATO water is fed into the sump via a float valve. It is set higher then both the avast pressure switch and dual floats but lower then the tsunami.
So, it goes
ATO resivour > check valve for just in case but not needed under normal operation >
Diaphragm pump > Tsunami AT1 pressure switch > apex outlet < dual inline floats and avast pressure switch and separate high sump float
> float valve > sump
Yeah, probably overkill. And thats just for my ATO. I've got things so setup for my AWC, lime dosing, carbon dosing, return pump, skimmers, and even the back overflow of the display. I've got input switches everywhere. [emoji1]
I've got 3 BoBs just about filled.
Here's the new pressure switch and float valve.
The old switches still in use for the ato. Hard to see the dual floats.
