Answer in brief

An orderly reminder for cleaning, refilling, circulation, testing, and recording the first safe-use readings.

Before draining

Read the spa manual first. Turn off equipment as directed, identify the approved drain route, and check local water-disposal rules. Have the correct filter-cleaning supplies, test method, and labeled treatment products ready. Do not mix chemicals or pour incompatible products together.

A practical refill sequence

Treat this as an organizational sequence, not a substitute for your model's startup directions.

  • Drain the old water by the method specified for your spa.
  • Clean accessible shell surfaces, waterline, cover, and filter according to the manufacturer; address visible slime or buildup before refilling.
  • Refill through the manufacturer-recommended point to the indicated water level.
  • Restore circulation and verify that pumps, jets, and heating equipment operate normally.
  • Test the fresh water; adjust sanitizer and pH using current labels and the spa manual, one product at a time.
  • Allow the required circulation time and retest before anyone uses the spa. Record the refill date and final readings.

When startup is not routine

A spa that has been idle, has visible biofilm, or may have been associated with illness needs more than an ordinary checklist. Keep it out of use and follow qualified or public-health guidance for the specific situation.
