Where each walk sits in the schedule

  1. 01quarterly

    Domestic water storage tank quarterly maintenance checklist

    Every quarter, walked with the domestic water equipment. A stored-water sanitary problem is invisible until someone tastes it or a sample fails.

    Run by: The plumbing or maintenance tech on the quarterly round.

  2. 02annual

    Domestic water storage tank annual maintenance checklist

    Once a year, scheduled with a supply changeover or low-demand window so the tank can be drained and taken out of service.

    Run by: The plumbing service lead on the annual potable water service.

What most often fails on a domestic water storage tank

  • An overflow or vent screen is torn or missing, giving insects or vermin a path into stored potable water.
  • Level controls hang so the tank barely turns over, and stagnant water in the bottom goes stale.
  • A hatch gasket or seal is bad, so surface water or debris can enter around the lid.
  • Tank disinfected but returned to service without confirming a clearing sample, so a contamination problem is put right back into the potable supply.
  • Sediment and biofilm cleaned from the walls but left in the bottom, so it re-suspends the first time demand stirs the tank.
