He said it will only continue until the sump refills to its proper level. The only problem I see is that to have a signifigant amount of "rainwater", you will have to allow the sump to evap alot of water before it kicks on, and that may cause bad salinity swings. I can see it working on a large system, where 5g or so of evap wouldnt change salinity very much.
