If you’re having a sewer problem and you’re trying to diagnose it, it’s good to think of your sewer like a tree. Your main sewer line is the trunk of the tree where all the sewage passes through. Your secondary lines, (toilets, sinks, miscellaneous drains) are the branches on the tree that—when having issues—at least don’t affect the other branches nearly as much.
Pardon our tree analogy, but it’s incredibly helpful when talking about whether or not you need a sewer line upgrade. The trunk of your tree should be able to pass sewage effectively through it. Otherwise, you’ll see major problems in every branch of the tree (every secondary sewage system) and you’ll have many drains that lose effectiveness. A plumber in Lake Worth, FL will already know this and, when the time comes, will suggest upgrading your sewer line to make sure it can handle what your home puts through it.
