My main sewer line was draining slow and would actually back up into my basement through the washing machine drain in the basement after heavy water drainage (long shower, big washing machine load) I had a drain cleaning company snake it out. His snake came to a stop down the line. He thought I had a break in the line. So I called the city and they were able to use a bigger snake to reach all the way to the main sewer line. Then they used a camera and after 6-8 feet they hit water. They think there is a belly in my sewer line They inspected the rest of the line and saw no breaks in the line. They closed up the line and left. I thought since they were able to reach the main sewer line with the snake, that any blockage would be cleared out and water would be able to get past the belly and drain out of the main sewer line instead of backing into my house. Even with the belly full of water, wouldn't the point where my line exits be higher than the point where it exits into the main sewer? I used my washing machine shortly after the city sewer guys left and after a short time water started backing into my house again. Any ideas of what can be causing this? My next course of action now is to replace my sewer line.

Snaking will NOT remove years of grease or soap deposits. For that you need a water Jetter to scour the piping correctly

If the guy you called used less then a 3/4" snake x 100 feet you may want to consider hiring a master plumber who has the right equipment and knows how to properly use it

The city crew was able to get all the way to the main line with a 3 inch wide blade on the snake. Wouldn't that be big enough to allow the water to flow?

Many sewer lines have a dip because of settling or improper installations and can go for decades without having to be repaired or replaced

Because of a new phenomena called "water seeks its own level" depending on how severe the dip is how deep the water level will be and what solids are left behind to trap sewerage and other debris from slowing past the dips found in many disposal systems..

If the deflection if not that great to trap large solids left behind then routine jetting or snaking will keep stoppages to a minimum Once a year is normal in severe cases

Snaking generally does not come close to scouring sewer or drain lines as water jetting does

The science behind water jetting is the debris flows downstream as the lines are cleared

Picture placing a rod in sand or FOG (fats oil or grease) as soon as the rod is removed the gap closes

Now picture using a garden hose in sand or soil IT Dissipates again Jetting is ideal for soft stoppages and snaking for roots tags and hard build up inside of piping systems
