Winterizing Your Spa
Winterizing your spa is very important!
As water freezes, it breaks the plumbing apart, cracks fittings, and can explode the pump. Even heating elements will expand to an irrepairable point if you live in a freezing area and fail to winterize your spa.
What you will need:
- Wet/Dry Vacuum (ShopVac)
- 1-3 Gal RV Antifreeze
- Channel lock pliers (16” will work best)
- Funnel or baster
- 2-3 hours of your time
*Drain your spa – often, pre-treating it beforehand is recommended so that whatever water may be left in the spa will not cause problems over the winter.
*Vacuum all the jets and injectors, until there is no water left.
*Remove your filter and vacuum at the plumbing, avoiding the O-Rings.
*If you have an air channel, turn on the power and make sure the pumps are NOT running. Turn your air blower on until water no longer comes out. Turn power off.
*Loosen the plumbing connections at your pump and at your heater. Vacuum all water.
*Reconnect the plumbing to the heater, the lower of the two connections on your pumps.
*Add RV anti-freeze to the pump using a funnel or baster. Most pumps take about 4 oz.
*Re-attach your pump unions.
*Add about 1 oz. RV anti-freeze to each jets with your funnel/baster.
*Add RV anti-freeze to plumbing attached to your filter until it runs out of the intakes at the foot of the spa.
*Add anti-freeze to the air channel/air injectors. This might be tedious, but it will be worth it!
If you get heavy snow, place ¼” plywood over your cover to help enforce it. You can also cover your spa with a tarp and strap it down. Your hot tub is an investment… don’t freeze your investment!
