If you\u2019re leaving a hot tub sitting at a cabin or vacation home from November through April, you\u2019re looking at five months where a hard freeze can split plumbing, crack manifolds, and destroy equipment. We see this every spring\u2014owners come back to a spa full of cracked PVC, a blown heat exchanger, or a Balboa VS or EL control pack that shorted out from water that froze and expanded inside the heater housing.
What\u2019s Actually at Risk
- Plumbing lines & manifolds: Trapped water expands and cracks rigid PVC fittings, especially at glue joints and 90-degree elbows.
- Heater assembly: Water left in the heat exchanger tube will split it. Replacing a heater tube on a Balboa M7 or Gecko?
Our Winterizing Process, Step by Step
This isn\u2019t just pulling a drain cap and walking away. Here\u2019s what we actually do on every winterization visit:
1. Flush & Drain
We run a line flush product through the system with jets on high to break up biofilm inside the plumbing. Then we open the main drain and the drain plugs on each pump\u2014most spas have two to three drain points that aren\u2019t obvious.
2. Forced Air Blow-Out
We use a high-volume blower through each jet line, the air channel, and the heater loop. This pushes residual water out of low spots, elbows, and check valves that gravity draining misses. This step is where DIY winterizing usually falls short.
3. Antifreeze in the Lines
We run non-toxic propylene glycol antifreeze (rated to \u221250°F) through every plumbing line, the ozone injector line if equipped, and the Sundance MicroClean or standard filter housing.
4. Equipment Protection
We pull drain plugs from all pumps and the heater, leave them inside the equipment bay in a labeled bag, and remove the filter cartridge.
5. Cover Prep
We clean the underside of the cover, inspect the vapor barrier, and secure the cover with straps or clips so wind and snow load don\u2019t shift it.
Common Mistakes with DIY Winterizing
We fix a lot of freeze damage every spring on spas where the owner or a handyman attempted winterization. The intention is right, but the execution usually misses critical details.
Top Issues We See
| Mistake | What Happens |
|---|---|
| Only gravity draining | Water sits in low-point elbows and check valves, freezes, and cracks fittings |
| Skipping the blower step | Pump volutes and heater tubes retain 1–2 cups of water\u2014enough to cause damage |
| Using automotive antifreeze | Ethylene glycol is toxic and contaminates the shell; propylene glycol is what you need |
| Leaving filter cartridge installed | Trapped water in the Sundance MicroClean or Pleatco cartridge freezes and splits the filter housing |
| Not pulling pump drain plugs | Residual water in an Aqua-Flo or Waterway pump cracks the wet end housing |
Vacation Home & Cabin Scheduling
Most of our winterizing calls come from owners who have cabins near Liberty Lake, Newman Lake, or just across the Idaho line. Timing and coordination matter when you\u2019re not on-site regularly.
When to Schedule
- Ideal window: Mid-October through mid-November, before overnight lows consistently hit the mid-20s.
- Latest safe date: Once nighttime temps drop below 20°F regularly, you\u2019re gambling. We\u2019ve seen freeze damage as early as late October in cold years.
- Spring re-opening: We also handle spring startup\u2014refill, re-install drain plugs, flush the antifreeze, check equipment operation, and balance water chemistry.
Coordination for Out-of-Town Owners
If you\u2019re not local, we can work with your property manager or neighbor for access. We\u2019ll send photos of completed work and a written summary of what was done and any issues we spotted\u2014like a cracked cover, aging pumps, or corroded terminals on the control board that should be addressed before spring.
We service properties throughout eastern Spokane County and the north Idaho border. If your cabin is within about 30 minutes of Liberty Lake, we can get to you.
