When a person has a blockage in their sewage system they often try to fix it themselves by adding an acid or a base such as Drano in an attempt to dissolve or dislodge the problem. These chemicals can get into the plumbers eyes when the sewage is splashed during the repair. The plumbers skin during the repair does come into contact with the sewage water. The owner of the toilet might not report to the plumber they have already tried Drano a highly caustic base .
Drain snake. This is a simple, shorter version of the big gas-powered snake that plumbers use to clear clogs deep in your drains. But if the clog is not so deep, owning one of these can save you a good bit of money. They come in different lengths and you can buy powered versions, but a simple 25' snake with a hand-powered crank will set you back less than $25.
