Question: How do I drain my tub?

Answer: How you drain your tub depends upon what you are doing with it after the water is out. 

  1. Drain water to improve water quality - you are going to fill it up immediately afterwards.
  2. Drain water to repair equipment (e.g. jets, pumps, ozonator, fittings, et. al.)
  3. Drain the water for non-use during warm months.
  4. Drain water and winterized the tub
Below are the instructions to completely remove the water in order to winterize or to perform repair. 

If you are simply replacing the water, start a syphon with a garden hose or use a tub vacuum.


  • 2 gallons of NON-TOXIC (R-V type) antifreeze (for winterizing only)
  • a strong wet/dry vacuum (shop vac)
  • a turkey-baster
  • 1 or 2 light plastic bowls approximately 5" diameter
  • TIME approx. 2 hours


  1. Drain your tub.
  2. With the wet-vac vacuum out any water remaining in the foot-well. Then with each jet in the open position, vacuum each jet nozzle until no more water comes out. DO NOT FORGET the small ozone jet in the foot-well.
  3. With the vacuum over the whirlpool jet nozzle(s) and plastic bowls over the suction covers in the footwell, change it to each diverter position until there is no more water being drawn out.
  4. You can apply a Teflon based lubricant (Magic Lube by Aladdin) to the gaskets on the pump, heater, and drain spigot to help avoid them from drying out.
  5. Winterizing Only: Remove your filter, clean it and place in storage until you restart your tub. Pour NON-TOXIC antifreeze into the filter canister until it runs out into the foot-well of your tub through the suction covers.
  6. With the turkey-baster, squirt a small amount of NON-TOXIC antifreeze into each jet. Usually the side jets will take around one ounce, and the whirlpool jet(s) will take several ounces (about 5 squirts per whirlpool jet). DO NOT FORGET the small ozone jet that is located in the foot-well of your tub.
  7. Place the cover on the tub, and place a tarp over the tub and cover. Making sure to securely tie down the tarp. The tarp will help reduce the amount of weather your tub is exposed to.


When a tub is drained and left empty, o-rings and pump seals can dry out and loose their ability to seal properly. You should closely inspect for small leaks in the equipment area when you do your restart. If you are unsure of the location of the o-rings and pump seal, contact your dealer for help. If replaced early the damage caused by these failures can be inexpensive to fix.


When restarting your tub, you will want to fill the tub and run all of the jets on high speed for 10-15 minutes. This will help flush the residue of the antifreeze out of the plumbing. Then drain the tub, clean the sides with an approved cleaner, place your filter back into the filter canister, re-fill your tub and balance your chemicals. You may notice slightly more foaming than normal when you first start using your tub, this can be reduced with anti-foaming agents and generally gets better over the first week or two of usage as the filter removes the anti-freeze and organic residue left behind after rinsing and cleaning.

Make sure you check your filter at least once per week and rinse it out as needed for the first few weeks. You may also find it necessary to soak your filter in a filter cleaner after a few days, depending on the level of contaminant left in the tub after the re-start.
