"I had Treasure Enterprises do a pool liner replacement, had them set up a swim spa, and had them supply and install a hot tub. They are great people to work with, and offered great suggestions and recommendations (that i wish I would have taken). I am very satisfied with all the pool related work that was done as everything is working perfectly. I also had them pour a new stamped concrete patio which turned out absolutely beautiful."

"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

Hot tub repair costs are less expensive than purchasing a new one, especially if your warranty is still intact. You can shop for a secondhand unit or find a deal for a trade-in. If the price to repair your hot tub is higher than the cost of a new one, consider replacing your unit.

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.

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.

If you want to have a chemical-free spa, or if you are wondering how to keep your hot tub clean naturally, there are several options. Some individuals choose to run their hot tub without treatment at all and simply clean it more often (although you risk bacteria, fungi, and algae growth if you take this route); others use natural products like vinegar or Borax. Ozone, ultraviolet light, and electrolysis systems are also eco-friendly ways to have a clean hot tub without chemicals. Saltwater hot tubs are popular with people who are sensitive to chlorine, bromine, and other traditional hot tub chemicals.

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.
