If you suddenly find that you have a main line stoppage there are a couple of things you can do. You can either call a professional plumber to clear it or you can clear it yourself.
Calling a plumber is the easiest course of action in most cases. But, if you decide that you would rather try to clear the clog yourself it can be done. You will need to start by renting a sewer drain snake. This piece of equipment is a must for clearing a sewer drain clog. Like most other drain snakes, a sewer drain snake can be rented by the hour or by the day.
Once you have the right drain machine you can proceed with clearing the clog. When you are snaking a sewer drain it is advisable to have one or even two helpers on hand. One person should serve as a spotter in case the drain snake gets kinked and another can keep watch inside at the toilets.
