I have a CPR overflow and a wife that would quickly bring this hobby to an end if there was a flood in our living room. Knowing what I know now, I should have drilled the tank, but I'm a little beyond that now. The issue with the CPR overflows is the reliance on a mechanical pump to remove the trapped air in the siphon. CPR recommends a Tom Aquatics Aqua Lifter—Dosing Pump to do the job. The problem with this setup is that this unit WILL fail eventually. When it does and you aren't there watching the tank, you will get a flood. Here is my idea and maybe it has been thought of already.
Attached to the line coming from the CPR Overflow you have a plastic "Y” that allows for two dosing pumps to run at once drawing from the one outlet on the overflow. The chances of two pumps failing at the same time are very small. This dual pump design should allow for you to have a failover pump until you can replace the failed pump, thus avoiding disaster.
Thoughts?
Has anyone seen these "Y" connections for airline tubing? If you have, where can I find them?
If anything this setup would at least give me piece of mind when I'm at work or away for the weekend.
