"Juston he is amazing! Poseidon pool service company is a big reason why we started using their service but Juston is the main reason why we stay with this company. They service our pool to a level like Iâ  ve never experienced before. Iâ  ve owned many many pools in my lifetime and Iâ  ve never had such a good quality of pool service at a great price. Cole the owner is fantastic but nobodyâ  s as good as Juston"

Pool and Spa Servicing FAQs, answered by experts

Hot tub heaters typically last seven to 10 years, though some might only last five years if not properly maintained. You can maximize your hot tub heater’s lifespan by ensuring the water’s pH level is properly balanced.

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.

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.

Most hot tubs will experience leaks due to wear and tear in the plumbing or the shell itself. The second most common issue is a heater malfunction due to the ongoing heat stress on moving parts. Finally, clogs happen in hot tub jets, especially when it’s time to change the filter.
