[Snappy]

I'd be careful of hooking it straight to the sump, heavy danger. I was having problems with my dosing pump in the res staying on because the float valve in the sump would stick so I put it on a timer and now no more flooding. Maybe you can use a bigger res for while you're away and impliment that type of idea. I just use a large garbage can for mine. If you can fill a larger res with enough water to last your vacation that is what I would do. It's worth the $15 at Crappy Tire to be safe.
