"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

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.

Yes, air baths are good for you. They promote relaxation, improve circulation, and can even hydrate your skin. Since they’re gentler than water jets and whirlpools, they are a good choice for a wide range of homes and users, from children to adults. You can maximize the benefits by using them regularly for stress relief and by pairing the bubble effects with calming music, low lighting or chronotherapy, aromatherapy, and other relaxation techniques.

No. In fact, some owners prefer to “summerize” their hot tubs and use them primarily over winter to enjoy the contrast of cold and hot water. It’s possible to keep the tub filled and running year-round, and some pros may even recommend this method compared to the work and risks of a full winterization every year.

However, keeping the hot tub running will require additional resources. You’ll use more power and more chemicals to keep it in good shape. Weigh the pros and cons of your situation before making a decision.

Regular water testing, filter cleaning, and chemical balancing are essential for keeping water clean and equipment functional.

Though a hot tub has many benefits, there are a few cons. Mainly, hot tubs require a lot of maintenance. You’ll need to deep clean yours quarterly, test the pH at least once or twice a week, and add sanitizing chemicals once a week. They also have relatively high ongoing costs since you’ll need to pay for electricity and repairs.
