What?!? You didn't know we were installing a swimming pool?? Neither did I! But seriously, back story:
As most of you know I have a 55 gallon freshwater fish tank. In order to keep it squeaky clean I do a 10% water change once a week. To easily do this I have a special tool. One end screws onto your sink faucet and contains a value. Switch it one way and it pushes water through a hose to your tank, switch it the other way it it allows the water to run straight through the valve into the sink which creates a suction and sucks water out of the tank. On the other end of the hose is a 1 foot section on stiff pipe that you use to poke around in the tank and suck the water out. It has an on/off valve on this end that you can use to stop the flow of water instead of running back and forth from the sink.
This setup worked well as the bathroom is a hop, skip, & a jump away from the aquarium. However, when we remodeled the bathroom we got a new faucet which doesn't allow things to be screwed onto it. No big deal, we have one of those large utility type sinks in the laundry room downstairs. So I purchased some similar sized hose from Home Depot, and patched in a longer length so it would reach downstairs. This has been working fine for the past several months.
Normally, after I finish refilling the tank, I just walk downstairs and shut the water off at the sink instead of using the cut off valve at the end of the hose. Don't ask my why, that's just how I did it. Well for whatever reason when I did my weekly water change at about 11pm last night (usually just takes 5 mins), when I finished filling the tank back off I cut off the water at the cut off and the end of the hose instead of at the sink. Big mistake! I immediately heard a POP and then the sound of Niagara Falls coming from downstairs.
I ran downstairs. Turns out that the sink downstairs has much more pressure than a normal sink, and when I cut off the water it blew the hose apart where I had connected the new length in. Now I had water spewing everywhere from TWO places. One from the hose coming from the sink (which was still on), and one coming from the hose leading back to the fish tank (it was still stuck in the fish tank, so now it was siphoning water out of the tank into our downstairs). I froze. I didn't know where to run first. I grabbed the line coming from upstairs and pinched it which stopped the flow from the tank. Next I stretched over to the hose coming from the sink and with my other hand still holding a kink in the hose coming from the tank, I put a kink in the supply line......POP! The other end of where I patched the new length of hose into the original hose popped loose and now water was gushing into the laundry room! I froze again! What to do!?! So with the water gushing into the laundry room I ran upstairs and pulled the hose out of the aquarium to stop the water from siphoning, and then ran back downstairs and shut off the water in the sink in the laundry room. SO MUCH WATER! I then spent the next hour and used pratically every towel in the house to sop up the laundry room floor and try to dry the carpet as best as I could in the den. I put a box fan downstairs and then worn out, I finally crawled into bed. When we got up this morning I told Jen what happened and she found it all incredibly funny.

Needless to say I will be investing in one continuous length of hose before my next water change.
Thankfully when I checked before I left for work things are feeling much dryer.
