"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 questions, answered by experts

If you don’t clean your hot tub filters, they’ll build up dirt and grime, preventing them from filtering out contaminants like dirt and bacteria. The dirty water will then circulate through the filter and back into the hot tub, leading to dirty water, a damaged pump and jets, and low heat. This can lead to higher hot tub costs because you may have to pay for repairs.

If your hot tub is well-maintained, covered tightly, and the water is balanced and sanitized correctly, it can remain unused for up to two weeks without significant issues. Beyond this period, the water quality may start to deteriorate, potentially leading to the growth of algae and bacteria. However, it's crucial to note that this timeline can change due to factors like water temperature, sanitation levels, and the quality of your hot tub cover. Regular maintenance and water testing are essential to ensure the water remains safe and clean during periods of inactivity.

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.

Similar to a hot tub, swim spas last anywhere from five to 20 years, depending on quality and your attention to maintenance. The best way to increase the lifespan of your swim spa is to carefully maintain it—including draining it around every six months to deep clean the parts.

You should put chlorine in your hot tub on a regular basis. To keep bacteria away, keep the chlorine level in your hot tub at between 3-5 mg/l, which may mean you need to add chlorine daily or at least every two to three days. Don’t add chlorine to your hot tub water more than once per day.
