Heh, I did something similar. Accidentally knocked the hose off my return pump(OMG, 6000 LPH straight up is a lot of water!) and it tripped the RCD when everything in the sump got soaked. So I dried everything off and flipped the RCD back on. FOOOSH*CLICK* Everything was soaked again because I'd forgotten to put the hose back on.
It's hose clamped on now.
