One slow sink is a local clog. But when the kitchen, bathrooms, and laundry all drain sluggishly at the same time, the trouble is almost always farther downstream — in the main line everything shares.
The tell is simultaneity. If running the washing machine makes the basement floor drain back up, or flushing a toilet slows the tub, the blockage is in the main line below where your branch drains join together.
A partially blocked main is a backup waiting to happen. Every load of laundry and every shower pushes more water toward a bottleneck that's already struggling. Clearing it now prevents raw sewage from coming up the lowest drain in the house.
We clear the main through your cleanout and, if the clog keeps returning, camera the line to find out why. Roots, grease, and bellies are the usual suspects.
