Where each walk sits in the schedule
- Domestic water storage tank quarterly maintenance checklistquarterly
- 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.
- Domestic water storage tank annual maintenance checklistannual
- 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.
