Fine the main drain opening ports. They are often in the garage, basement or a crawl space.
They will be in a "Y" angle and closed with a steel or plastic cap with a square fitting. They are short pipes that branch off of the main ones.
If you are having trouble finding them, follow drain pipes in your home around the foundation.
Prepare for the mess. Place a bucket underneath to catch any debris that comes out.
You will also want to spread a tarp or old towels on the floor and around the drain to catch any overflow.
Take off the cap with the pipe wrench. Try to do this as slowly as possible as water that is backed up will want to flow out.
Take off the cap as slowly as possible until the water stops leaking out and then remove it completely.
Use a plumber's snake. The plumber's snake can now be placed inside the main drain to clean out any debris that is clogged inside.
Push the snake into the drain until you come across resistance. The resistance will be the clog.
Turn the snake on to push through clogs. Keep going until you have no more length of snake to push in.
Then pull snake back and repeat in the main drain to the other direction.
Put the cap back on, making sure that it is snug. Check your drains that were previously backing up.
