MY CPR runs with a Rio 600 re-venturi attached. It has run without incident for overy 18 months now.
As this pump doesn't really need to run all the time, I've connected it to my fresh water replenishment circuit. When evaporation triggers the system, the Rio comes on spits out any air trapped in the siphon. This contributes to random water movement, and the pump tends to activate every 5 or 10 minutes.
This is probably not good for the pump, but it has lasted at least long enough to justify it's cost....and it is still going.
