I feel so stupid! I was tired one night but knew I needed to do a quick WC so I hooked everything up and drained the tank. But when was filling I decided to go and sit down, oh was that a bad idea! Fell asleep for 20-30 minutes and woke up to loud splashing on the tile floor! Good thing I had everything hooked up to reliable surge protector or else I wouldn't be here today. I run to shut the water off and in the mist of it I slip from the soaked floor and break the corner of my table with my elbow. I get up soaked and finally shut the water off and then glance at the damage. At the tank area there was about an inch to inch and half of water and that led to almost 3/4 of the house! Good thing I don't got carpet because it would of been ruined. All in all took me about 2-3 hours to clean with just a bunch of old rags and a 5g bucket. This btw happened 12am so I didn't end up going to sleep till almost 5 and had to work a double that day... Anybody else have horror stories when doing water changes?
