I feel for you! I've already had 2 mishaps in the last 24 hours with my still new tank. First I dropped in a bag of carbon and didn't realize it got stuck to the skimmer intake and the skimmer ran all day wet skimming, filled up the cup and leaked some. So I got a lecture about paying attention to how the things work in the sump.
Then yesterday, I decided to make some water and had my bucket in the kitchen with the hose in it and I hear this big THUMP sound and then I hear water spraying. I go to see what is going on and I see water coming out from under the cabinet where the RO/DI is. I start freaking out and trying to get the cabinet open - we have a child proof lock on it, one of the really annoying magnet ones - and once I get the cabinet open, I'm getting sprayed and water is going VERY fast all over the kitchen floor and island behind me. I started turning off water and finally got the right one on the third valve.
I was soaked from the skin out and had the baby on my back and 2 boys coming in to gawk at the "mess Mommy made!" We used ALL the towels I had just washed and folded to mop up the water (hey, the kitchen got mopped!) and hubby just had to reattach a hose when he got home.
hmmmm, tile floors are sounding better & better
