How to Properly Drain and Refill your Hot Tub

Draining and refilling your hot tub on a regular basis will save you time, money on chemicals. Fresh water yields are most comfortable. The average person will refill their hot tub every 6 – 8 weeks.

  • Begin with a full hot tub. Add one bottle of Swirl Away, Mineraluxe Cleanse and Drain, or Trio #3 pouch to clean your hot tub plumbing. Circulate the tub of the time listed on the label of your chosen product.
  • Next, turn off the circuit breaker for the spa’s electrical line. Then remove the hard thermal cover and drain out the spa. This can be done by hooking a garden hose to the spa’s bottom drain spout, or by actually pumping the water out with a submersible pump.
  • Next, remove your hot tub filter and chemically clean it following the package directions on Mineraluxe Filter Revive or SpaGuard Filter Brite.
  • Soak up all the remaining water from inside the spa with towels or a mop or suck it out with a shop vac. Make sure you get all the water out, especially in the footwell. Clean a hot tub acrylic with Dazzle Pool and Patio Cleanse or Bioguard Off the Wall. Rinse well.
  • Using your garden hose, refill the hot tub THROUGH THE SUCTION FITTING (where your filter usually sits). This will help prevent air locks in the system.
  • While the spa is filling, put the hard cover back on the unit. Secure the cover to the spa so that the wind will not flip it up. Use Dazzle Cover Cleanse or Swirl Away 2 (following the package directions) to cleanse and protect your hot tub cover. Tech tip- while the spa is filling, inspect the mechanical areas of your hot tub…. on portable, cabinetized spas, often vermin will try to nest inside spa cabinets over the winter. Thy can chew wires and cause expensive damage!
  • When your spa is half full, reinstall your cleaned or replacement filter.
  • When hot tub water is filled to the usual operating level (for most clients this is just the pillow height,) turn off your garden hose and remove it from the hot tub.
  • Turn of the circuit breaker to your spa.
  • Ensure your hot tub begins its ‘boot up’ process. The jets will start to run and your heater indicator light will be on.
  • Set your spa to the desired temperature and take a 1L water sample t Aqua-Tech for a Fresh Fill Analysis
