Will reactors underneath the tank cause a siphon in a power outage?

[djryan2000]

Dumb question. I am planning to have a pump in the sump of my AIO and then a reactor underneath the tank. It'll have a return nozzle above the water level. In the event of a power outage, I don't have to worry about a siphon, correct? I do have valves to prevent water from spilling out when I open the reactor.

edit:
this is what I am emulating


the pump will be in my sump and the reactor underneath the tank. I will use vinyl tubing and barbs.

As long as the reactor is higher then the pump, it will be fine.

In the event pf a power outage, depending on sump setup, the water level should be even across all chambers. No siphon would start.

the reactor would be below the pump. Looks like I have to fix that then. thank you!

As long as the output of the reactor is higher than the pump then it won’t siphon. It’s always in regards to height of input vs output.

Also if it’s an AIO then the pump is in the back and the return is in the same tank so even if it did siphon all of the water is contained in the tank and it wouldn’t matter

Think of it this way, if the reactor is a sealed chamber than it is functionally no different than having a piece of tubing going under the tank and then back up to the tank, if that makes sense.

got it. output is definitely higher than input. I orignally assumed I was all set but wanted to make sure I wasn't emulating a system that would have caused a disaster. Thank you!

The only way it could siphon would be if there was a leak on the reactor, then you would have a leak from the pumped water too.

It’s good of you to even consider what can start a siphon many hobbyists don’t and find out the hard way. When I first setup my ATO I started one and emptied my reservoir. Now anytime I do any plumbing I take it into consideration.
