"I hired Scott to fix our pool heater. He is very honest and charged me a very reasonable rate to replace the circuit board. He was also able to get our solar heater working again and helped troubleshoot an issue with our dirty pool filter. Highly recommended!"

Pool and Spa Servicing FAQs, answered by experts

Biofilm growth can cause a hot tub to feel slimy. Hot tub biofilm is a slimy substance that’s typically due to natural contaminants like makeup, soaps, skin oils, deodorants, or lotions. A hot tub can also have a slimy interior or slimy water if the tub’s filters are old or damaged, or if the hot tub isn’t properly cleaned. You should drain your hot tub, wipe away any slimy residue, then refill the water and use a spa purge product that prevents the buildup of biofilm.

Follow these general safety tips for spas and hot tubs:

  • Keep your exterior electrical receptacles covered and dry, especially around your hot tub and pool during periods of use.

  • Make sure you have a GFCI (ground fault circuit interrupter) properly installed to ensure no one gets accidentally shocked or injured by electrocution. 

  • Don’t use the hot tub or your pool during a thunderstorm. 

  • Before using the hot tub, have a certified electrician thoroughly inspect your hot tub and its wiring to make sure you’re in full compliance with all applicable local building codes. 

You can drain a hot tub very quickly by using a submersible pump rather than the hose-sized drain at the bottom exterior of the tub. A pump can move up to 30 gallons per minute, draining your hot tub in no time. Using the regular drain can take up to two hours.

Yes, but only if it is a freshwater tub (not saltwater) and if you make sure the chlorine and bromine levels are below 1 ppm.

To refill a hot tub after winter, start by opening up the tub and giving it a quick cleaning. If you use antifreeze, drain out the water then grab a hose and thoroughly clean the tub shell out, spraying water into each jet of the tub. 

Reconnect the hot tub and turn the power back on. When it’s time to fill the tub again, insert the hose into the filter well (if available). Avoid trapping too much air in the water lines, which can cause the pump to lock up when it starts again. Add the necessary chemicals and start the heating process. It will take some time—most of a full day—for the water to heat up again.
