Why keep a log

Drain problems rarely arrive all at once. A tub slows a little, a toilet gurgles once in a while, the kitchen sink takes longer to empty after the dishwasher runs. By the time a line backs up, it is hard to remember which came first. A simple log turns those scattered moments into a pattern.

Patterns are what point to causes. Clogs that follow heavy laundry days, appear after rain, or return on a regular cycle each suggest something different about where the blockage is and what it is made of. Print this page or copy the table into a notebook and keep it near the laundry or kitchen.

Also worth noting once

Reading your log

  • IfEvery entry involves the same single fixtureThenThe problem is likely in that fixture's trap or branch.
  • IfEntries involve several fixtures or the word 'rise'ThenSuspect the main line or lateral.
  • IfEntries cluster after laundry or the dishwasherThenLarge discharges are reaching a restriction; note which line.
  • IfEntries repeat on a cycle of weeks or monthsThenAsk about a camera inspection for roots or a pipe defect.

Common questions

How long should I keep the log?

Until the cause is found and fixed, and then keep it with your home records. It is useful for a future buyer or plumber.

Should I give the log to the plumber?

Yes. A photo of the page is enough and helps them decide what equipment to bring.

What if I only had one clog?

Write it down anyway. One entry with the cause noted is a baseline if problems return.
