Customer called us out for a clogged toilet in basement. While inspecting I checked out the water heater and sewage ejector pump. Sewage ejector pump was not sealed properly and leaking. The gfci was tripped so I flipped it back and the toilet drained. Water heater had shark bite fittings, leaking expansion tank and no support for the expansion tank. Customer is possibly under warranty for his house, if not he will call back.
