Some factors that determine the cost of plumbing services by the hour are the type of appliance being repaired, the extent of the damage and the price of replacement parts. A plumber's rates can also vary by the region in which the job is being performed.
When a toilet is clogged, the price can vary depending on which mechanism, if any, needs to be repaired or replaced. For instance, if pipes connected to a toilet are corroded or leaking, it can take several hours to replace the pipes and can be quite costly. Conversely, if there is no damage to the pipes, a simple snake line can unclog a toilet in less than an hour.
