Taking care of frozen toilet pipes starts with turning off the water supply. You can prevent pressure buildup and reduce the risk of the pipe being damaged by this action. Until the frozen section is thawed, it is best not to use the toilet. Apply warm water to the frosty pipe with a hair dryer, warm towels, heater or any other device which does not involve flame for the safety of the equipment and to be free from the risks of fire, etc. that an open flame would pose. Once thawed, the pipe must be tested to find any leakages or cracks and then the water should be turned on gradually. In places with a colder climate or where there are no other toilets available, electric toilet incinerators of Incinolet model may well act as the solution since such toilets require neither water nor septic connections.
