Plumbing/Overflow Questions

[philg3]

I'll read some more about Calfo's DSB bucket and see if i can make it work for this system.

Although i have never seen a Bean in real life, i wouldnt be surprised if the emergency standpipe overflowed a little while the water level was stabilizing.

Check Valves seem like the simple answer, but I have read about them failing as well, so that isnt exactly bulletproof. I have a DA RKL controller, and have been looking at programming some float switches, but they arent really fail-safe either. I guess noones setup is ever really bulletproof, but it would be nice if i could shoot guns in my living room without worrying about getting my feet wet, or at least go away for a day or two without stressing.

Currently i have my pump in sump, but if i drill the tank for an external pump it might make more room for Water Volume as well as allowing me to run the return chamber less full without the pump running dry. There are some space restrictions that I might have to work out.

The pump I currently have is a Sedra 7000, but I think that will have to be upgraded for this system. Anyone have any recommendations as far as Pump brand and size?
