Bits and parts are often damaged or missing on used hot tubs.
Things like dials, cushions, valves, jets, drink tray caps, skimmer weirs, drain/intake strainers, leaf catcher baskets, filters, covers, clips, etc.
You might not notice it or give it a second thought, but these “little things” might actually be important and can add up, and some may be expensive and/or hard to find/replace, or may not be available at all.
Tips:
-Scan the tub over carefully to see if you can spot anything missing or broken
-turn every dial and knob on the hot tub back and forth, & make sure they’re properly attached and mechanically functional
-gently tug on & wiggle each every piece that’s attached to the tub and not a part of the hot tub itself, looking for loose or damaged bits.
