Your confidence overwhelms me!
That thing's built really rather strongly and I'm confident that when it does leak, it'll just be minor seeping/trickling, so probably won't be spectacular enough for the £250

............Now i've said that it's gonna explode isn't it?...arse.
That's alright, we fixed the sink when we messed that up didn't we? Plus we're trained in electrics, not plumbing!

(for those that want to know what happened with the sink, wait until i decorate the pond.)
Erm......confused what you're getting at there, explain again?
I can video with my camera but would probably need to send to you to youtube it as i have no idea what to do there and i know you do
