We are leaving tomorrow for a 6 day vacation. Ruth walked into the master bedroom this afternoon and there was water flowing out of the master bath. The toilet tank had failed, cracked in half, water was spraying everywhere. I hit the water shut off and grabbed my shop vac. Sucked up at least 5 gallons of water. thankfully the bathroom floor is Linoleum and the master suite is waterproof Pergo. If this had happened tomorrow and we were gone for 6 days I can only imagine the damage and the cost. We did get a plumber to come out and install a new toilet. He said our subfloor suffered no damage.
