If plunging or a store-bought snake keeps buying you a week or two before it clogs again, the real cause usually isn't at the surface.
A plunger or a short cable often breaks a clog apart enough for water to pass, without actually removing what's built up along the pipe walls. That residue becomes the starting point for the next clog, usually within days or weeks.
A slight sag in the line, a rough joint, or a section where roots have begun intruding can act like a snag point — catching hair, grease, or debris every time, even after a full cleaning. Camera inspection can confirm whether that's what's happening at your specific clog point.
If the same fixture clogs repeatedly — a kitchen sink, for example — grease or food debris going down that drain regularly is often the simplest explanation. Professional cleaning resets the pipe, but it won't stop a clog that's caused by an ongoing habit.
If you've plunged or snaked the same spot more than twice in a few months, it's a sign the underlying buildup was never fully removed. A thorough mechanical or hydro jetting service clears the full diameter of the pipe rather than just punching a hole through the clog.
