ACAUTION
The water passing out of the drain valve may be extremely
hot. To avoid being scalded, make sure all connections are
tight and that the water flow is directed away from any
person.
Mineral buildup or sediment may have accumulated in the
old water heater. This causes the water heater to be much
heavier than normal and this residue, if spilled out, could
cause staining.
