When to call a licensed plumber
Water spreading across a floor, a warm spot on a slab floor, a leaking water heater, or sewage backing up into a drain needs a licensed plumber. Keep away from water near outlets or appliances, and shut off the water at the main valve only if you can reach it safely. If you smell gas near a gas water heater, leave the house and call your gas utility or 911 from outside. Never plug or cap a water heater's relief valve. Before anyone digs in your yard, call 811.
