I run a cold plunge repair company. We logged 722 faults since May — here's what actually breaks
Full disclosure: I own The Cold Standard, a cold plunge service company. Our techs tag every fault they find into a database, and I thought this sub would find the patterns useful:
• The circulation pump is the #1 failure (17.7% of all faults) and causes 40% of "unit completely dead" calls.
• Almost half of all problems are in the water path (pumps, filters, plumbing, valves): 48.8%. Many "my chiller is broken" calls turn out to be a clogged filter starving the pump.
• Chillers fail less than people think. Compressor or whole-chiller failures were only 7.2%.
• 31.6% were preventable, and where we could identify a cause, skipped maintenance was #1.
• Filter cartridges: 86% of filter cartridge faults were preventable.
• Commercial units were more often preventable than home units (45% vs 31%).
Repeat offenders we see:
• extension cords and power strips
• pool chlorine tablets in a plunge
• not pre-filling the filter housing (causes airlocks)
• hard-water scale
• biofilm in the lines
