"Well, the first time the replacement was ordered it was the wrong one, which of course, delayed the installation a week. When it was finally installed I had to pay an additional $850 for code upgrades. This I was not informed of by Home Shield. Then we noticed that there was water on the garage floor and found that the pipe coming in from the wall was leaking at the wall so had to call the plumbing company back out to fix it. They first tried to say it was not their fault but since there wasn't a leak before they installed they did fix it. I have used Home Shield a few times before and never had a problem. Some of the companies they use are not the best so you have to research them before you commit. I have found HS service to be good if you do your homework. At the end of the day I was without hot water for almost 3 weeks but it was do to the plumbing company they sent out."

Pool and Spa Servicing FAQs, answered by experts

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.

How often you change the water in your swim spa depends on how often you use it. Most manufacturers recommend changing the water every three to six months. If you use your swim spa throughout the seasons, it’s a good idea to set up a quarterly deep cleaning schedule. The ideal instructions should be in the owner’s manual.

Most hot tub motors can last between five and 10 years; however, hot tub motors can burn out sooner if the hot tub water is not maintained or if the motors themselves are not maintained or protected from the elements. Since hot tub motors (also referred to as spa pumps) power the jets and circulate the water, they are important for the functioning of your spa. Buying a quality motor, keeping the hot tub filter clean, and keeping the wet end of the motor wet and the dry end dry can help them last longer.

For a fully-foamed hot tub, freezing typically occurs when the temperature drops below 28 degrees Fahrenheit and remains at or below this level continuously for a minimum of 36 hours. If your hot tub and pumps are still operational, however, the water circulates, and this continuous movement helps prevent freezing, even in very cold conditions. This circulation, along with the insulation provided by the foam, helps maintain the water temperature and prevent it from freezing during extended cold periods. Still, if you’re not planning to run it regularly, be sure to winterize the hot tub properly to prevent damage from freezing.

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.
