Spa & hot tub
Spa and hot tub service
Sullivan’s services spas and hot tubs, both attached spas that share a pool’s equipment and standalone tubs with their own. A spa is not a small pool: the water volume is tiny, the temperature is high and the bather load per gallon is enormous, so chemistry moves in hours rather than days and filters need attention far more often. Just over half the pool properties in our service area have a spa as well.
Why a spa is not a small pool
-
Chemistry
A spa is a fraction of the volume at twice the temperature.
Tested and balanced on its own terms, and drained on the cycle the volume needs.
-
Filter
Spa cartridges load far faster than a pool’s.
Cleaned and replaced on a spa schedule, element by element.
-
Hardware
Jets, blower, heater, circulation pump — and the cover.
Attached-spa valves, spillover and switchover faults included.
Sullivan’s runs fixed weekly routes rather than covering the metro at random, so the drive times stay short enough for same-week work. See the areas we cover.

- Spa water tested and balanced on its own terms, not the pool’s
- Filter cartridge cleaning and replacement on a spa schedule
- Drain, clean and refill on the cycle the water volume actually needs
- Jet, blower, heater and circulation-pump faults
- Attached-spa valve and actuator problems, including spillover and switchover
- Cover condition checked — a failing cover costs more in heat than it does to replace

How often should a hot tub be drained?
A useful rule is the tub’s gallons divided by three, divided by the number of daily bathers, in days — which for most household tubs lands between two and four months. Heavy use shortens it. Water that has stopped responding to chemicals is telling you it is past due.

Why does my spa use so much more chemical than my pool?
Volume and temperature. A spa can be a hundredth of a pool’s water at twenty degrees warmer, so every bather and every hour of heat has a hundred times the effect on the chemistry.
