More goodies arrived! This time, the HOPEFULLY fail safe Apex driven Auto Top Off. Alk components were purchased from autotopoff.com
First let me start by saying, although riskier, I do not want a topoff resivuar. It adds one more pump to go bad, or go empty, and require me to manually fill. However with that comes the added risk of a flood to to supply of endless water. For that reason, I opted with multiple layers of safety built in.
From left to right:
1/4" RO line solenoid. This will be be triggered by the main low water sensor in the sump (4th from left). This will open the flow of water to the sump, and turn off the water once the proper height is reached.
Next is a flow lock device. This is the last line of defense. This sits on the floor, and the RO line runs through it. If any water touches it...it closes the line, stopping all water flow. This will be placed in series BEFORE my RO unit. So even a leak in the RO unit will shut the entire setup down.
Third: this bracket mounts in the sump, and will have 3 float switches attached. One set at a high water level to shut off the solenoid if the main float is to get stuck. The lower will be to alert me if the water reaches a critical low level that would damage the pump. This would indicate something went wrong in water delivery.
The long float switch on the far right is actually for my skimmer cup or collection container. This will shut down the skimmer to prevent it from running over.
Finally:. I don't have it shown here, but I will also have a physical float valve that turns on and off the water as well that sits inside the sump at the proper level.
So again, HOPEFULLY, with all these layers of protection, I am hoping to have a fail-safe, ultra low maintenance topoff setup..
I will also note that this option was chosen over a prefab topoff because I want the ability to control and monitor the entire system via Apex. A prefab ( like the Tune system) would likely do a good job (though nearly all require a holding tank), it couldn't be easily monitored online. My goal is to have every part of this system monitored and viewable on my phone!
