Why do my drains keep clogging?

Repeat clogs are the most misdiagnosed problem in plumbing, because every individual clearing works. The auger opens a channel, water flows, everyone is happy — and the underlying condition keeps narrowing the pipe until the next backup. If you are on your third clearing of the same line, you are not unlucky. The line is telling you something.

What it is saying depends on the pattern. Kitchen lines that slow every few months are usually grease-scaled — decades of cooking narrowing the pipe from the inside. A main line that backs up every spring is roots finding a joint, swelling with the growing season. A newer home with recurring slowdowns often has a bellied section where trench backfill settled. And in older neighborhoods like Bellmead, original cast iron scales and flakes until a 4-inch line behaves like a 2-inch one.

The honest path: after a repeat clearing, the conversation should turn to cause — where the problem section is, what condition it is in, and what the options cost. Sometimes the answer is scheduled maintenance clearing, which is a legitimate budget strategy. Sometimes it is a section repair. What it should never be is surprise clearing number six.
